Common Interface to Cryptographic Modules (CICM)
draft-lanz-cicm-03

Abstract

This memo presents a programming interface to standardize the way software programs manage cryptographic modules and use cryptographic services offered by modules. Although a number of interfaces for commercial environments have been standardized and are in use, this is the first generic cryptographic interface to be developed that supports cryptographic modules separating two security domains and is thus ideal for the high assurance environment. The interface has been designed to also allow less demanding environments to take advantage of its features.

1. Introduction

This document defines the high-level entities of a programming interface for high assurance cryptographic modules called Common Interface to Cryptographic Modules (CICM) based on the logical model outlined in [CICM-LM].

1.1. Requirements Language

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119].

1.2. Definition Language

CICM is defined using Interface Definition Language (IDL) [IDL], a specification language that describes a software interface in a language-neutral way. IDL compilers can generate a functionally equivalent CICM interface binding for common programming languages. The use of IDL in CICM is not intended to either prescribe or preclude a particular communications protocol such as General Inter-ORB Protocol (GIOP) [CORBA] between programs in different address spaces or on different devices.

Additionally, CICM does not use the IDL exception mechanism to report errors. See Extensions for more information.

1.3. IDL Language Mapping Conventions

Memory responsibilities and calling conventions MUST follow the appropriate IDL language mapping conventions.

1.4. Endianness

Endianness is the byte ordering used to represent data stored in a computer or transmitted between computers. A big-endian ordering of bytes is REQUIRED by CICM.

1.5. Blocking and Non-blocking Calls

All CICM methods block (wait for the operation defined by the method) to complete before returning, unless they are explicitly defined as non-blocking. For example, the CICM::Encrypt::Stream::encrypt method (defined in [CICM-CM]) blocks when sending data on a stream to be encrypted, while its sibling CICM::Encrypt::Stream::encrypt_non_blocking is identified not only in its name as non-blocking, but also clearly within the documentation for the method.

1.6. Assumptions

The following assumptions were made in the development of CICM:

• Library implementers may implement part of the specification (refer to the sections on Conformance and Extensions, for the normative rules).
• A client program initiates cryptographic transformations with a cryptographic module via the CICM API. Multiple client programs may concurrently access a single module from a single security domain, but CICM provides no support for controlling access to a module by two or more client programs.
• A module may be implemented as hardware, firmware, or software component, or any combination thereof.
• Although CICM is intended for use in high assurance environments, its use is not precluded in less demanding environments.
• One or more entities between the API library and the module translates CICM commands or interfaces to module-specific commands or interfaces.
• CICM makes no provision in the design of the API to guarantee the confidentiality, integrity, or authenticity of commands and data between a client program calling the API and a module. However, such protections can be applied in the library or runtime system software.
• Specialized hardware (e.g., hardware access tokens, key fill devices, trusted displays) independent of a module may require host (and thus API) interaction or may require no host interaction.

1.7. Specification Organization

The CICM specification is composed of five documents.

• [CICM-LM] provides an informative (non-normative) underlying logical model and terminology,
• this document defines the basic types and rules for conformance (Section 6) and extension (Section 7),
• [CICM-MM] defines module management capabilities,
• [CICM-KM] defines key management capabilities, and
• [CICM-CM] defines channel management capabilities.

The informative material is for informational purposes; it assists the reader in the understanding and use of the specification but does not contain provisions required for conformance.

The namespaces, interfaces, datatypes, methods, and attributes that comprise the specification are presented in a prescriptive manner. For each category, each namespace is described followed by the interfaces contained within it. The datatype, method, and attribute definitions then follow each interface definition.

2.3.2.2. CICM::CryptoModule Methods

Method CICM::CryptoModule::configure_fill_interface()

CICM::Status configure_fill_interface(
in  CICM::Buffer interface_parameters,
in  CICM::LocalPort fill_port
);

Configure a module key fill interface.

Remarks:

• This method accepts an opaque buffer containing a module-specific data structure specifying fill port configuration parameters.
• The format of the interface parameters value is not defined by CICM. The Implementation Conformance Statement (see Section 6) MUST reference a standard format or define a module developer-specific format implemented by the module for this datatype.

Parameters:

• [in] interface_parameters Opaque buffer containing the fill interface configuration parameters.
• [in] fill_port Fill port to configure.

Returns:

• S_OK, S_GENERAL_ERROR, S_NON_FUNCTIONAL, S_OPERATION_FAILED, S_POLICY_VIOLATION, S_MODULE_RESOURCES, S_HOST_RESOURCES, S_INVALID_STATE, S_ALARM_STATE, S_MODULE_NOT_AVAILABLE, S_TIMEOUT, S_NOT_AUTHENTICATED, S_NOT_AUTHORIZED, S_INVALID_DATA_BUFFER, S_KEY_FILL_DEVICE_NOT_CONNECTED, S_LOCAL_PORT_INVALID, S_LOCAL_PORT_INCOMPATIBLE, S_LOCAL_PORT_IN_USE, S_TOKEN_NOT_PRESENT, S_TOKEN_ADMIN_NOT_PRESENT

Method CICM::CryptoModule::reset()

CICM::Status reset();

Perform a software-initiated reset on the module.

Remarks:

• This method attempts to restart a module in the event of a module failure or in the event a module has entered an alarm state. A CICM::S_OK status denotes that the command was accepted by the module or runtime system, not that any specific action has been initiated as a result of the reset request.

Returns:

• S_OK, S_GENERAL_ERROR, S_NON_FUNCTIONAL, S_OPERATION_FAILED, S_POLICY_VIOLATION, S_MODULE_RESOURCES, S_HOST_RESOURCES, S_INVALID_STATE, S_ALARM_STATE, S_MODULE_NOT_AVAILABLE, S_TIMEOUT, S_NOT_AUTHENTICATED, S_NOT_AUTHORIZED, S_TOKEN_NOT_PRESENT, S_TOKEN_ADMIN_NOT_PRESENT

2.3.3. Interface CICM::Iterator

Interface CICM::Iterator

Type CICM::Iterator::Status

typedef CICM::UInt32 Status;

Indicates whether or not there are more items over which to iterate.

Constant CICM::Iterator::C_ITERATOR_HAS_NEXT

  C_ITERATOR_HAS_NEXT = 0x00006031;

There are more items in the list.

Constant CICM::Iterator::C_ITERATOR_NO_MORE

const CICM::Iterator::Status
  C_ITERATOR_NO_MORE = 0x00006032;

There are no more items in the list.

2.3.3.2. CICM::Iterator Methods

Method CICM::Iterator::has_next()

CICM::Status has_next(
out CICM::Iterator::Status has_next
);

Used with get_next() to determine if one or more additional elements are available to be retrieved.

Remarks:

• For elements that have not already been processed, changes in the state of the list/database over which the iterator is being run during the lifetime of the iterator will be reflected in the results from calls to retrieve iterator elements.

Parameters:

• [out] has_next Indicates whether more elements are available to be retrieved.

Returns:

• S_OK, S_GENERAL_ERROR, S_NON_FUNCTIONAL, S_OPERATION_FAILED, S_POLICY_VIOLATION, S_MODULE_RESOURCES, S_HOST_RESOURCES, S_INVALID_STATE, S_ALARM_STATE, S_MODULE_NOT_AVAILABLE, S_TIMEOUT, S_NOT_AUTHENTICATED, S_NOT_AUTHORIZED, S_TOKEN_NOT_PRESENT, S_TOKEN_ADMIN_NOT_PRESENT

3. Module Management

Module management capabilities are defined in [CICM-MM].

4. Key Management

Key management capabilities are defined in [CICM-KM].

5. Channel Management

Channel management capabilities are defined in [CICM-CM].

6. Conformance

Many modules will not require the implementation of the full specification to support a module's capabilities. Thus, the CICM conformance model was developed to be flexible. This model does not normatively prescribe the implementation of specific functional subsets of the specification. Instead, CICM outlines a normative Implementation Conformance Statement (ICS) and associated documentation that MUST be supplied with any conformant implementation.

The ICS guides the developer of a library for a specific module to record the implementation state and presence of extensions for each section of the specification. The gradations of the implementation state are relatively coarse: "implemented," "partially implemented," or "not implemented." Extensions are identified as interface extensions or status code extensions, and are recorded as "existing" or "not-existing." An analysis of the resulting matrix enables a software developer using the API or an architect designing a system integrating with a specific cryptographic module to quickly determine if a developer's library will meet user requirements. Those specification sections marked "partially implemented" or for which extensions are indicated may require additional analysis to determine what elements have been extended or are not implemented, and the resulting repercussions on the system utilizing the library.

CICM interfaces are organized into three major sections: module management, channel management, and key management. Each section is partitioned differently into logical subsections in the ICS. The module management section is partitioned into subsections by individual module managers. The channel management section is partitioned into subsections by channel type. The key management section is partitioned into subsections by the type of key and class of operation performed on the key.

An Implementation Data Specification (IDS) based on the ICS also is required. For each implemented interface containing an opaque data parameter (module-specific or infrastructure-specific parameter not described in detail in the specification), the IDS requires a detailed specification of the data structure for each parameter.

An implementation conforms to the specification if it meets the following conditions:

• A CICM library implementation MUST include only the subset of interfaces corresponding to the functionality supported by the module for which it was designed. The implementation MUST implement the full subset of interfaces implemented by the module. A library MUST implement a non-zero set of interfaces corresponding to functionality implemented by the module that reasonably maps back to the CICM interface and is appropriate for the system in use.
• A CICM library MUST minimally implement the CICMRoot and CryptoModule interfaces, both fundamental parts of the specification without which no other interfaces can be implemented. The CryptoModule interfaces MUST implement minimally one manager, which must be at least "partially" implemented (e.g., simply implementing non-functional inherited or dependent interfaces is non-conformant).
• A CICM library MUST be made available with a corresponding ICS.
• A CICM library MUST be made available with an IDS corresponding to its ICS. The format of any module-specific data structures defined as opaque data elements in the specification with which a client program using CICM must have knowledge MUST be documented by the module developer and MUST be made available as the IDS. If the implementation implements no interfaces with opaque data parameters and includes no extensions, the IDS MUST state that the implementation requires no IDS entries.
• A CICM interface is only conformant if it also implements any inherited and all dependent interfaces (e.g., the interface Encrypt::WithSignConduit defined in [CICM-CM] requires that symmetric keys and asymmetric keysets defined in [CICM-KM] also be implemented). The exception is the CICM::ChannelManager interface, which only requires the implementation of one or more of its inherited interfaces.
• Any interfaces that are not implemented precisely as specified in the normative portion of the specification MUST be identified as extensions to the specification.
• Extensions to the CICM specification MUST NOT contradict nor cause the non-conformance of functionality defined in the normative specification, MUST follow the requirements and guidelines of the normative specification, and MUST be clearly described in supporting documentation.
• Memory responsibilities and calling conventions MUST follow the appropriate IDL language mapping conventions.

6.1. Implementation Conformance Statement Contents

A library implementation conforming to the CICM specification MUST be accompanied by an ICS. The ICS is generated by the module developer or implementer of a CICM-conformant library for a specific cryptographic module configuration (including any associated hardware/firmware/software) and MUST contain the following information:

• Details regarding the product and version of the specification to which it conforms, including:
  • CICM version number
  • Product manufacturer/name, version number (hardware, firmware, and software)
  • Configuration details, including patch state
  • Date of claim
• Capability Support Matrix, listing the major sections of the specification and their implementation state ("I"=implemented, "P"=partially implemented, and "N"=not implemented), and the presence of any extensions
• List of developer-defined extensions to specification. Extensions MUST be divided into four classes: Interface extensions, status code extensions, event listener extensions, and constant extensions. Extensions MUST be documented as specified in the IDS.
• List of unique identifiers for all supported cryptographic algorithms, organized by class of algorithm, and all supported key agreement protocols; each algorithm/protocol unique identifier MUST be in CICM-specified format (refer to the section Generating Unique Identifiers).

The following represents a sample CICM ICS.

6.2. Implementation Data Specification Contents

The IDS serves as the detailed supporting documentation for the ICS. Conformance with the CICM specification requires that:

• Each implemented interface that accepts an opaque data object MUST reference an existing standard or document the data structure associated with that object in sufficient detail to allow an implementer to create new objects and manipulate existing objects. The exception to this requirement is those cases where a client program will NOT be allowed to manipulate the opaque data object (e.g., CICM::KeyProtocolReceiver::get_from_module defined in [CICM-KM] or CICM::PackageImporter::import_segment defined in [CICM-MM]).
• Each interface extension listed in the ICS MUST be clearly described in the IDS and MUST be documented in a manner similar to the normative CICM documentation.
• Each status code extension listed in the ICS MUST be referenced in the IDS with a corresponding description, numeric code, and a list of CICM interfaces to which the extension applies.
• Each module or channel event listener extension listed in the ICS MUST be referenced in the IDS with corresponding description, numeric code, and data structure definition associated with the event_data parameter, if applicable.
• Each extended constant value listed in the ICS MUST be referenced in the IDS with corresponding description and numeric code.

Examples of interfaces requiring an IDS entry to be conformant include:

• CICM::SymKeyManager::get_key_by_id defined in [CICM-KM], where the key identifier is specific to the key management system in use.
• CICM::LogManager::retrieve defined in [CICM-MM], where the log returned from the method call will vary from module-to-module.
• CICM::ModuleEventListener::event_occurred defined in [CICM-MM], where the event_data parameter passed to a client program as part of an event notification is system specific.

Note that the event listener callbacks (CICM::ModuleEventListener::event_occurred and CICM::ChannelEventListener::event_occurred) require that the event_data parameter be described for each event type implemented.

6.3. Generating Unique Identifiers

CICM does not provide a list of algorithms with their corresponding normative unique identifiers. Instead, normative guidance is provided for generating the identifiers for the different classes of algorithms defined in the specification and for key agreement protocols. These identifiers are used by software developers when specifying algorithms or protocols as parameters to CICM methods. This identifier generation guidance is intended to promote interoperability, and encourage the use of the same identifier for algorithms among vendors.

Three major components may be combined to form a unique algorithm identifier: an algorithm (ALGO), that may be precisely specified as an encryption algorithm (ENCRALGO), signature algorithm (SIGALGO), MAC algorithm (MACALGO), or hash algorithm (HASHALGO); a mode (MODE); and an encoding scheme (SCHEME), that may be precisely specified as an encryption scheme (ENCRSCHEME) or a signature scheme (SIGSCHEME). Note that some components above may not apply to certain algorithms. In addition, applicable modes and components need not always be specified. For encryption and signature algorithms, if a length is required, the length SHALL be appended to the algorithm without a dash ("-") delimiter. Otherwise, components are concatenated with a dash ("-").

Alternatively, an identifier can consist of a simple personality designation (PERSONALITY). The personality consists of a combination of parameters that comprise a logically complete crypto, and specifies a specific equipment type or configuration for which algorithm, mode, and any other parameters are implicit. The designation may contain dashes.

Certain algorithms may be appropriate for and thus listed under more than one algorithm class. Below are the classes of algorithms and format of the identifiers for each class:

Asymmetric encryption algorithm identifiers (AsymEncrAlgorithmId)

• Format: ENCRALGO [ "-" ENCRSCHEME ] | PERSONALITY
• Examples: "RSA1024-OAEP"

Asymmetric signature algorithm identifiers (AsymSigAlgorithmId)

• Format: SIGALGO [ "-" HASHALGO [ "-" SIGSCHEME ]] | PERSONALITY
• Examples: "DSA-SHA1" or "RSA1024-SHA256-PKCS1V1_5"

Symmetric encryption algorithm identifiers (SymEncrAlgorithmId)

• Format: ENCRALGO | PERSONALITY
• Examples: "AES128" or "3DES"

Symmetric MAC algorithm identifiers (SymMacAlgorithmId)

• Format: MACALGO [ - HASHALGO ] | PERSONALITY
• Examples: "HMAC-SHA1" or "UMAC"

Hash algorithm identifiers (HashAlgorithmId)

• Format: HASHALGO | PERSONALITY
• Examples: "MD5" or "SHA1"

Key wrap algorithm identifiers (KeyWrapAlgorithmId)

• Format: ENCRALGO | PERSONALITY
• Examples: AESKW

Two major components may be combined to form a key agreement protocol identifier: the key agreement protocol including its version number (KEYAGREEPROTO) and the protocol's associated algorithm suite including its version number (ALGOSUITE). The following is the format for key agreement protocol identifiers.

Key agreement protocol identifier (ProtocolId)

• Format: KEYAGREEPROTO "-" ALGOSUITE
• Examples: "IKE2.0-FIREFLY"

Note that the resulting identifiers may not be compatible with those identifiers defined for other module developers' implementations. A client program utilizing an identifier corresponding to one algorithm for a specific module may be required to modify the identifier for the same algorithm for a different type of module. Discrepancies may be discovered through a brief review of the ICS "Supported Algorithms" section.

6.4. Conformance Verification

In the future, test assertions may be made available to allow results from different organizations to be compared, and to provide proof of conformance to the specification.

7. Extensions

An extension is a mechanism to define functionality beyond what is defined in the official specification. In the interest of promoting interoperability, extensions to the specification are discouraged except where necessary. Extensions to the specification enable module developers to add functionality unanticipated by the specification developers and to support proprietary features.

7.1. Extending an Interface

Developers may augment CICM interfaces by extending CICM IDL by adding new methods/attributes to existing interfaces or by deriving off existing CICM interfaces. Extensions SHALL be documented in the ICS.

7.2. Extending Codes

CICM codes are constants that share a single 32-bit space. A number of datatypes for different purposes correspond to ranges in this space. The "CICM" codes are normatively defined in the specification; the "extended" codes are module developer-defined extensions. The codes, with their corresponding ranges and uses, are as follows:

CICM status codes

• 0x00000000 - 0x00001000

Extended status codes

• 0x00001001 - 0x00002000

CICM module event codes

• 0x00002001 - 0x00003000

Extended module event codes

• 0x00003001 - 0x00004000

CICM channel event codes

• 0x00004001 - 0x00005000

Extended channel event codes

• 0x00005001 - 0x00006000

CICM generic constants

• 0x00006001 - 0x00007000

Extended generic constants

• 0x00007001 - 0x00008000

RESERVED

• 0x00008001 - 0x7FFFFFFF

Normatively-defined CICM codes SHOULD be used whenever possible. If any of the extended codes above are defined, they MUST be documented as specified below.

7.2.1. Extending Status Codes

The return value from CICM methods informs the caller of the status of the call. CICM does not use the IDL exception mechanism to report errors.

The specification normatively defines a set of error codes in the range of 0x00000000 - 0x00001000, which may not be modified or extended. A block of codes in the range of 0x00001001 - 0x00002000 are reserved for module developer-defined status codes. Any codes defined in this range MUST be documented in the ICS.

7.2.2. Extending Module/Channel Event Codes

The specification supports registering and unregistering user-defined channel event listeners for specific module and channel events. Module events in the range of 0x00003001 - 0x00004000 and channel events in the range of 0x00004001 - 0x00005000 are normatively defined and may not be modified or extended. A block of module events in the range 0x00003001 - 0x00004000 and channel events in the range of 0x00005001 - 0x00006000 are reserved for module developer-defined events. Any codes defined in this range MUST be documented in the ICS.

7.2.3. Extending Constants

A number of constants are normatively defined for specification use in the range of 0x00006001 - 0x00007000. Module developer-defined constants may be specified in the range of 0x00007001 - 0x00008000. Any constants defined in this range MUST be documented in the ICS.

8. IANA Considerations

[RFC Editor: Please remove this section prior to publication.]

This document has no IANA actions.

9. Security Considerations

This document defines basic aspects of the CICM specification and the normative rules for conformance and extensions. Other aspects of CICM contain important security considerations.

9.1. Unauthorized Usage

CICM provides several interfaces related to mitigating unauthorized usage in [CICM-MM]. Furthermore, [CICM-KM] discusses aspects of how authorization can be indirectly controlled via key white lists and black lists.

9.2. Inappropriate Usage

CICM defines several status codes related to inappropriate usage. For example, attempting to use an invalid key (S_KEY_INVALID) or specifying an inappropriate algorithm (S_ALGO_INVALID). The wide range of status codes relate to the anticipated mechanisms in which using the interface may fail. Additionally, module developers can extend the set of status codes to accommodate their own needs and prevent inappropriate usage.

Appendix A. Status Codes

Each method defined in CICM returns a status value to inform the caller as to the outcome of the call. The documentation for each individual method lists the status codes that may be returned in the event a call to the method results in failure.

The status value CICM::S_OK is returned if a method completes successfully. The output parameters of any methods that return a status other than CICM::S_OK are invalid and MUST NOT be referenced or used.

CICM methods can fail for a variety of reasons, including:

• Invalid, illegal, out-of-range, or poorly formed parameters
• Resources insufficient or unavailable
• Unsupported capabilities
• Policy violation
• Hardware failure.
