Internet-Draft Data Transmission Security of IR October 2023
1. Introduction
Identity resolution system is an important network infrastructure for
the Industrial Internet. It provides codes, registration and
resolution services for industrial equipment, machines, materials,
parts and products to achieve interoperability, secure sharing and
intelligent association of heterogeneous information, which is an
important cornerstone for the rapid development of the Industrial
Internet. Typical global identity resolution systems in existence
include the Handle system [RFC3650] [RFC3651], the Object Identifier
(OID) resolution system [OID], etc. In order to ensure the security
of data transmission involved in the Industrial Internet identity
resolution systems, the security technical requirements are
formulated to enhance the security of the entire Industrial Internet
identity resolution system and reduce the security risk caused by
data leakage. The security technical requirements can be applied to
the planning, construction, operation and management of data
transmission security of Industrial Internet identity resolution
systems.
2. Scope
This draft specifies the security technical requirements for the
transmission of Industrial Internet identity resolution data.
This draft applies to the planning, construction, operation and
management of the Industrial Internet identity resolution data
transmission security of the relevant parties.
3. Terms and Definitions
3.1. International Root Node
International root nodes are the top-level service node of the
identity resolution system. They are not limited to specific
countries or regions. Their main role consists of two aspects: (1)
to provide public root-level identity services for the global scope;
(2) and to provide services such as data synchronization and
registration resolution for different levels of nodes in local
country.
3.2. National Root Node
A national root node is the top-level node within a country or a
region, which is connected to the international root node and
secondary nodes, provides top-level identity resolution services for
the whole country.

Internet-Draft Data Transmission Security of IR October 2023
3.3. Secondary Node
A secondary node is a public node providing identity services for
specific industries or multiple industries. Secondary node is
responsible for allocating identity and providing identity
registration, identity resolution and identity data services for
industrial enterprises. Two types of secondary nodes exist, namely
industry secondary nodes and comprehensive secondary nodes.
3.4. Enterprise Node
An enterprise node is an intra-enterprise identity service node which
is able to provide identity registration, identity resolution service
and identity data service for a specific enterprise. An enterprise
node should be connected to a secondary node.
3.5. Recursive Node
A recursive node is the key entrance facility of the identity
resolution system, whose responsibility is to cache the resolution
data in the process of identity resolution, in order to reduce the
amount of resolution data processing and improve the efficiency of
resolution services.
3.6. Transmission Security
Protect the confidentiality, integrity, availability and timeliness
of data transmitted over the network.
3.7. Privacy
Privacy refers to the authority that individuals have to control
their information, including who collects and stores it and who
discloses it.
3.8. Personal Data
Personal Data refers to the information that a natural person can be
identified directly through the data, or indirectly through the data
combined with other information.

resolution and management service system proposed in this draft
mainly means that the identity is written into the device and is
responsible for collecting product information, including device
model, device type, generation batch, generation date, generation
site, device production information link, device description data
link, etc., integrate this information into identity data, and then
publish it to the data exchange system for access by identity
resolution enterprise nodes. Among the identity resolution
enterprise node, the identity resolution secondary node, and the
identity resolution root node, the process of data synchronization
between the application scenarios, the collection of data
transmission technologies used, is used to provide security assurance
and security support for the Industrial Internet identity data
transmission.
The scope of Industrial Internet identity data transmission security
protection specifically includes the security and the security
support of the data transmission interface within and between the
functional domains of the Industrial Internet identity resolution
system. Its role is in the whole life cycle of the system (planning
and design, development and construction, operation and maintenance ,
abandonment and exit).

Data transmission should comply with the following common
requirements:
Wang, et al. Expires 21 April 2024 [Page 8]
Internet-Draft Data Transmission Security of IR October 2023
1) Support the information integrity check mechanism during
transmission to realize the transmission integrity protection of
management data, authentication information, sensitive information,
important business data and other data (such as: check code, message
abstract, digital signature, etc.).
2) Should have transmission delay and interrupt handling capabilities
to ensure the integrity of the data.
3) Cryptographic technology should be used to protect the integrity
of important data in transmit.
4) Measures should be taken to recover the data when data integrity
is compromised.
7.2. Data Transmission Availability
The timeliness and accuracy of the data should be guaranteed during
data transmission. Specifically:
1) Timeliness: the feature of identifying historical data received or
data beyond the time limit. Specifically, the data comes from the
system using a unified time allocation/correction mechanism, and the
data should include time stamps, etc.
2) Accuracy: When there is an acceptable error in the data, there is
an overload to ensure the normal acquisition of the data in time.
7.3. Data Transmission Confidentiality
When transferring data, it is necessary to ensure the confidentiality
of the data, including:
1) For important data, authenticate information and important
business data such as user passwords, biometrics, private keys,
symmetric keys, product order information, and unique identity of a
device (Handle ID), a certain strength encryption algorithm or other
effective measures should be used to guarantee confidentiality.
2) Appropriate security protocols (such as HTTPS, SSH, IPSec, TLS,
etc.) should be used to safeguard the data being transmitted.
7.4. Data Transmission Authentication
Ensure the legitimacy of the identities of both parties in the data
transmission, which means, ensure the identity authentication of the
subject to the object before the interaction, and establish a trusted
transmission path.
Wang, et al. Expires 21 April 2024 [Page 9]
Internet-Draft Data Transmission Security of IR October 2023
7.5. Data Transmission Strategy
Establish a formal transmission strategy to protect the security of
all types of information transmitted through communication
facilities, and meet:
1) Clarify the type and scope of information that can be transmitted
in plain text.
2) For sensitive data, such as user passwords, biometrics, private
keys, symmetric keys, etc., an encrypted transmission strategy is
required.
7.6. Data Transmission Protocol
The protocol should address the safe transmission of internal and
external business, and meet:
Cryptographic algorithms such as data abstract, signature, and
authentication shall use the cryptographic algorithms and
combinations of abstract, signature, and authentication required by
national regulations or national mandatory standards.
7.7. Maintenance and Update of Transmission Protocol
The confidentiality protocol for data transmission should be
regularly maintained and updated so that the procotol should reflect
the requirements for data transmission security protection and meet:
1) The transmission security protocol needs to be reviewed every year
to ensure that the agreement should reflect the requirements for data
transmission security protection
2) When new services are launched or existing services are changed,
the transmission security protocol needs to be audited and updated if
necessary
7.8. Log and Audit
The transmission system shall log and audit the following security
failure events. The content of the log shall at least contains date/
time, event type, event subject, event description, event result
information, and meet the following requirements:
1) The results of data transmission channel creation
2) Transmission device online monitoring abnormalities and alarm
events
Wang, et al. Expires 21 April 2024 [Page 10]
Internet-Draft Data Transmission Security of IR October 2023
3) Malicious program intrusion alert event
4) Configuration modification operations caused by administrators/
non-administrators
8. Protection Dimension
From the perspective of security requirement analysis and protection
scheme design, the following implementable protection solutions can
be considered.
8.1. Physical Security
Ensuring physical security encompasses device hardware security,
anti-interference measures, and prevention of transmission
interception. Qualified devices may also incorporate security chips,
encryption, key storage, and device identity authentication
capabilities. Without robust physical security measures in place,
implementing other security measures becomes challenging.
8.2. Authentication Mechanism
This involves incorporating multiple authentication and access
control mechanisms, such as dual-factor authentication and
fingerprint scanners, suitable for IoT devices. Enhancing the
security of human-machine interaction and machine-machine interface
ensures the overall data security.
8.3. System Security
It involves reinforcing the security of the operating system,
including digitally signing the operating system code to prevent
tampering. Additionally, the access interfaces (APIs) provided by
the system externally need to be secured. Data transmission
interfaces should be analyzed to provide encryption and integrity
protection functions.
8.4. Transmission Security
The protocol design at the transport layer should systematically
analyze security and privacy threats and risks, ensuring the
derivation of appropriate safety requirements. Preventing privacy
violations should also be considered as one of its primary
considerations.
Wang, et al. Expires 21 April 2024 [Page 11]
Internet-Draft Data Transmission Security of IR October 2023
8.5. Network Security
Traditional network security devices and functions can still serve as
means or supplements to Perimeter Security in the Industial Internet.
Examples include gateway security, firewalls, antivirus and anti-
malware products, intrusion detection systems (IDS), and intrusion
prevention systems (IPS).
8.6. Application Security
IoT application developers must prioritize the security and privacy
protection of their applications. When designing IoT systems, a
comprehensive analysis of security should be conducted, finding a
suitable tradeoff between user experience and protection.
8.7. Cloud Security
Considering the constrained processing power of IoT devices, security
solutions for cloud data in the Industrial Internet should take into
account the distinctive characteristics of IoT data, including its
high volume endpoints and rapid flow.
