[Account request does not specify the portal in the request body, only the HTTP package includes this information. This is probably a bug.]
A user interacts with a Mesh service through a Mesh portal provider with which she establishes a portal account.
For user convenience, a portal account identifier has the familiar <username>@<domain> format established in [~RFC822].
For example Alice selects example.com as her portal provider and chooses the account name alice. Her portal account identifier is alice.
A user MAY establish accounts with multiple portal providers and/or change their portal provider at any time they choose.
The first step in creating a new account is to check to see if the chosen account identifier is available. This allows a client to validate user input and if necessary warn the user that they need to choose a new account identifier when the data is first entered.
The ValidateRequest message contains the requested account identifier and an optional language parameter to allow the service to provide informative error messages in a language the user understands. The Language field contains a list of ISO language identifier codes in order of preference, most preferred first.
POST /.well-known/mmm/HTTP/1.1 Host: example.com Content-Length: 90 { "ValidateRequest": { "Account": "test@prismproof.org", "Language": ["en-uk"]}}
Figure 1
The ValidateResponse message returns the result of the validation request in the Valid field. Note that even if the value true is returned, a subsequent account creation request MAY still fail.
HTTP/1.1 200 OK Date: Mon 18 Sep 2017 04:26:53 Content-Length: 190 { "ValidateResponse": { "Status": 201, "StatusDescription": "Operation completed successfully", "Valid": true, "Minimum": 1, "InvalidCharacters": ".,:;{}()[]<>?|\\@#"}}

[Note that for the sake of concise presentation, the HTTP binding information is omitted from future examples.]
The first step in creating a new personal profile is to create a Master Profile object. This contains the long term Master Signing Key that will remain constant for the life of the profile, at least one Online Signature Key to be used for administering the personal profile and (optionally), one or more master escrow keys.
For convenience, the descriptions of the Master Signing Key, Online Signing Keys and Escrow Keys typically include PKIX certificates signed by the Master Signing Key. This allows PKIX based applications to make use of PKIX certificate chains to express the same trust relationships described in the Mesh.

Since the device used to create the personal profile is typically connected to the profile, a Device profile entry is created for it. This contains a Device Signing Key, a Device Encryption Key and a Device Authentication Key:

A personal profile would typically contain at least one application when first created. For the sake of demonstration, we will do this later.
The personal profile thus consists of the master profile and the device profile:

Once the signed personal profile is created, the client can finaly make the request for the service to create the account. The request object contains the requested account identifier and profile:

The service reports the success (or failure) of the account creation request:
{ "CreateResponse": { "Status": 201, "StatusDescription": "Operation completed successfully"}}
Figure 10
Connecting a device to a profile requires the client on the new device to interact with a client on a device that has administration capabilities, i.e. it has access to an Online Signing Key. Since clients cannot interact directly with other clients, a service is required to mediate the connection. This service is provided by a Mesh portal provider.
All service transactions are initiated by the clients. First the connecting device posts ConnectStart, after which it may poll for the outcome of the connection request using ConnectStatus.
Periodically, the Administration Device polls for a list of pending connection requests using ConnectPending. After posting a request, the administration device posts the result using ConnectComplete:
Connecting Mesh Administration Device Service Device | | | | ConnectStart | | | ----------------------> | | | | ConnectPending | | | <---------------------- | | | | | | ConnectComplete | | | <---------------------- | | ConnectStatus | | | ----------------------> | |
Figure 11
The first step in the process is for the client to generate a device profile. Ideally the device profile is bound to the device in a read-only fashion such that applications running on the device can make use of the deencryption and authentication keys but these private keys cannot be extracted from the device:

Figure 13
One of the main architecutral principles of the Mesh is bilateral authentication. Every device that is connected to a Mesh profile MUST authenticate the profile it is connecting to and every Mesh profile administrator MUST authenticate devices that are connected.
Having created the necessary profile, the device MUST verify that it is connecting to the correct Mesh profile. The best mechanism for achieving this purpose depends on the capabilities of the device being connected. The administration device obviously requires some means of communicating with the user to serve its function. But the device being connected may have a limited display capability or no user interaction capability at all.
If the device has user input and display capabilities, it can verify that it is connecting to the correct display by first requesting the user enter the portal account of the profile they wish to connect to, retreiving the profile associated with the device and displaying the profile fingerprint.
The client requests the profile for the requested account name:
{ "GetRequest": { "Account": "test@prismproof.org", "Multiple": false}}
Figure 14
The response contains the requested profile information.

Figure 15
Having received the profile data, the user can then verify that the device is attempting to connect to the correct profile by verifying that the fingerprint shown by the device attempting to connect is correct.
Connection of an Internet of Things 'IoT' device that does not have the ability to accept user input requires a mechanism by which the user can identify the device they wish to connect to their profile and a mechanism to authenticate the profile to the device.
If the connecting device has a wired communication capability such as a USB port, this MAY be used to effect the device connection using a standardized interaction profile. But an increasing number of constrained IoT devices are only capable of wireless communication.
Configuration of such devices for the purpose of the Mesh requires that we also consider configuration of the wireless networking capabilities at the same time. The precise mechanism by which this is achieved is therefore outside the scope of this particular document. However prototypes have been built and are being considered that make use of some or all of the following communication techniques:
After the user verifies the device fingerprint as correct, the client posts a device connection request to the portal:
{ "ConnectStartRequest": { "SignedRequest": { "Identifier": "MCZKI-OKTQF-M3KQY-FKGTU-T3SOI-K33I3", "SignedData": { "unprotected": { "dig": "S512"}, "payload": " ewogICJDb25uZWN0aW9uUmVxdWVzdCI6IHsKICAgICJQYXJlbnRVREYiOiAiTUNG UTctTUFRN04tTVVFNkgtN0wzS0wtTTMzM1EtQlBVRUYiLAogICAgIkRldmljZSI6 ... fX0sCiAgICAiRGV2aWNlRGF0YSI6IFtdfX0" , "signatures": [{ "header": { "kid": "MCZKI-OKTQF-M3KQY-FKGTU-T3SOI-K33I3"}, "protected": " ewogICJhbGciOiAiUlM1MTIiLAogICJ2YWwiOiAiCjQ1dkRWQkg0VndGTHhWZ0lX VlI2MGxGSm1KY1B1aUI4aUo5V1g2TWhlSU9VZGZsUmtzcEQ2ZHpza3F1cjdWZC0K YVZyQ0lQR29jVldLVEF6OUFZN0U2QSJ9" , "signature": " kZn-7SOivXJjkhLiSZkz5KMM0X6dHnxNIvqIhBRMbldcmSGNadU3-pLz6UjHqMKR 1dYa4lmyPU1_9fv-z5T1JwCte5w7byv8HfJcqfbUgqtaVe5AIm7DugurvqKjOFb- uFM9FJKI356CuVJ4Qie7U_Xh3LJ0HJF5ipMWJOqskm2zh2DN7d3-hYGymwtEE8NZ _TqnmE1VlKZKUgnkrjFU1FgmAdBzp3zFJExFZzCOWcbxbqkohY3jiCIFecHqt8g7 RLSMqQST4VcL3KvIMLrvcXYdJGQixu_iFViMI66ijjdeuMaUHpK4NaMpMYk-0mcJ 65qFw1xv8rHL6S4QLdolng" }]}}, "AccountID": "test@prismproof.org"}}
Figure 16
The portal verifies that the request is accepable and returns the transaction result:
{ "ConnectStartResponse": {}}
Figure 17
The client can poll the portal for the status of pending requests at any time (modulo any service throttling restrictions at the service side). But the request status will only change when an update is posted by an administration device.
Since the user is typically connecting a device to their profile, the next step in connecting the device is to start the administration client. When started, the client polls for pending connection requests using ConnectPendingRequest.

As stated previously, the connecting device polls the portal periodically to determine the status of the pending request using ConnectStatusRequest:

[Should probably unpack further.]
Application profiles are published separately from the personal profile to which they are linked. This allows a device to be given administration capability for a particular application without granting administration capability for the profile itself and the ability to connect additional profiles and devices.
Another advantage of this separation is that an application profile might be managed by a separate party. In an enterprise, the application profile for a user's corporate email account could be managed by the corporate IT department.
A user MAY have multiple application profiles for the same application. If a user has three email accounts, they would have three email application profiles, one for each account.
In this example, the user has requested a PaswordProfile to be created. When populated, this records the usernames and passwords for the various Web sites that the user has created accounts at and has requested the Web browser store in the Mesh.
Unlike a traditional password management service, the data stored the Password Profile is encrypted end to end and can only be decrypted by the devices that hold a decryption key.
{Example.PasswordProfile1}
Figure 26
The application profile is published to the Mesh in the same way as any other profile update, via a a Publish transaction:
% Point = Example.Traces.Get (Example.LabelApplicationWeb1); {Point.Messages[0].String()}
The service returns a status response.
{Point.Messages[1].String()}
Note that the degree of verification to be performed by the service when an application profile is published is an open question.
Having created the application profile, the administration client adds it to the personal profile and publishes it:
{Point.Messages[0].String()}
Note that if the publication was to happen in the reverse order, with the personal profile being published before the application profile, the personal profile might be rejected by the portal for inconsistency as it links to a non existent application profile. Though the value of such a check is debatable. It might well be preferable to not make such checks as it permits an application profile to have a degree of anonymity.
{Point.Messages[1].String()}
The Mesh invites users to put all their data eggs in one cryptographic basket. If the private keys in their master profile are lost, they could lose all their digital assets.
The debate over the desirability of key escrow is a complex one. Not least because voluntary key escrow by the user to protect the user's digital assets is frequently conflated with mechanisms to support 'Lawful Access' through government managed backdoors.
Accidents happen and so do disasters. For most users and most applications, data loss is a much more important concern than data disclosure. The option of using a robust key recovery mechanism is therefore essential for use of strong cryptography is to become ubiquitous.
There are of course circumstances in which some users may prefer to risk losing some of their data rather than risk disclosure. Since any key recovery infrastructure necessarily introduces the risk of coercion, the choice of whether to use key recovery or not is left to the user to decide.
The Mesh permits users to escrow their private keys in the Mesh itself in an OfflineEscrowEntry. Such entries are encrypted using the strongest degree of encryption available under a symmetric key. The symmetric key is then in turn split using Shamir secret sharing using an n of m threshold scheme.
The OfflineEscrowEntry identifier is a UDF fingerprint of the symmetric key used to encrypt the data. This guarantees that a party that has the decryption key has the ability to locate the corresponding Escrow entry.
The OfflineEscrowEntry is published using the usual Publish transaction:
{Point.Messages[0].String()}
The response indicates success or failure:
{Point.Messages[1].String()}
To recover a profile, the user MUST supply the necessary number of secret shares. These are then used to calculate the UDF fingerprint to use as the locator in a Get transaction:
{Point.Messages[0].String()}
If the transaction succeeds, GetResponse is returned with the requested data.
{Point.Messages[1].String()}
The client can now decrypt the OfflineEscrowEntry to recover the private key(s).
The following classes are used as common elements in Mesh profile specifications.a
Most Mesh objects are signed and/or encrypted. For consistency all Mesh classes make use of the cryptographic data classes described in this section.
The PublicKey class is used to describe public key pairs and trust assertions associated with a public key.

Every Mesh Portal Service transaction consists of exactly one request followed by exactly one response. Mesh Service transactions MAY cause modification of the data stored in the Mesh Portal or the Mesh itself but do not cause changes to the connection state. The protocol itself is thus idempotent. There is no set sequence in which operations are required to be performed. It is not necessary to perform a Hello transaction prior to a ValidateAccount, Publish or any other transaction.
A Mesh Portal Service request consists of a payload object that inherits from the MeshRequest class. When using the HTTP binding, the request MUST specify the portal DNS address in the HTTP Host field.
Base class for all request messages.
A Mesh Portal Service response consists of a payload object that inherits from the MeshResponse class. When using the HTTP binding, the response SHOULD report the Status response code in the HTTP response message. However the response code returned in the payload object MUST always be considered authoritative.
Base class for all response messages. Contains only the status code and status description fields.
[No fields]
The Mesh Service protocol makes use of JSON objects defined in the JOSE Signatgure and Encryption specifications.
The following common structures are used in the protocol messages:
Describes a Key/Value structure used to make queries for records matching one or more selection criteria.
Specifies constraints to be applied to a search result. These allow a client to limit the number of records returned, the quantity of data returned, the earliest and latest data returned, etc.
Report service and version information.
The Hello transaction provides a means of determining which protocol versions, message encodings and transport protocols are supported by the service.
Request validation of a proposed name for a new account.
For validation of a user's account name during profile creation.
Describes the proposed account properties. Currently, these are limited to the account name but could be extended in future versions of the protocol.
States whether the proposed account properties are acceptable and (optional) returns an indication of what properties are valid.
Note that receiving a 'Valid' responseto a Validate Request does not guarantee creation of the account. In addition to the possibility that the account namecould be requested by another user between the Validate and Create transactions, a portal service MAY perform more stringent validation criteria when an account is actually being created. For example, checking with the authoritative list of current accounts rather than a cached copy.
Request creation of a new portal account.
Unlike a profile, a mesh account is specific to a particular Mesh portal. A mesh account must be created and accepted before a profile can be published.
Request creation of a new portal account. The request specifies the requested account identifier and the Mesh profile to be associated with the account.
Reports the success or failure of a Create transaction.
[No fields]
Request deletion of a portal account.

Request deletion of a new portal account. The request specifies the requested account identifier.
Reports the success or failure of a Delete transaction.
[No fields]
Search for data in the mesh that matches a set of properties described by a sequence of key/value pairs.
Describes the Portal or Mesh data to be retreived.
Reports the success or failure of a Get transaction. If a Mesh entry matching the specified profile is found, containsthe list of entries matching the request.
Publish a profile or key escrow entry to the mesh.
Requests publication of the specified Mesh entry.
