Device Schema Extensions to the SCIM model

Introduction The Internet of Things presents a management challenge in many dimensions. One of them is the ability to onboard and manage large number of devices. There are many models for bootstrapping trust between devices and network deployments. Indeed it is expected that different manufacturers will make use of different methods. SCIM (System for Cross Identity Management) defines a protocol and a schema for provisioning of users. However, it can easily be extended to provision devices. The protocol and core schema were designed to permit just such extensions. Bulk operations are supported. This is good because often devices are procured in bulk.

Why SCIM for devices? Some might ask why SCIM is well suited for this purpose and not, for example, NETCONF or RESTCONF with YANG. After all, there are all sorts of existing models available. The answer is that the only information being passed about the device is neither state nor device configuration information, but only information necessary to bootstrap trust so that the device may establish connectivity.

Protocol Participants In the normal SCIM model, it was presumed that large federated deployments would be SCIM clients who provision and remove employees and contractors as they are enter and depart those deployments, and federated services such as sales, payment, or conferencing services would be the servers. In the device model, the roles are reversed, and may be somewhat more varied. A deployment network management system gateway (NMS gateway) plays the role of the server, receiving information about devices that are expected to be connected to its network. That server will apply appropriate local policies regarding whether/how the device should be connected. The client may be one of a number of entities: A vendor who is authorized to add devices to a network as part of a sales transaction. This is similar to the sales integration sometimes envisioned by Bootstrapping Remote Key Infrastructure (BRSKI) . A client application that administrators or employees use to add, remove, or get information about devices. An example might be an tablet or phone app that scans Easyconnect QR codes.

| SCIM | | | app |<-------------| Server | | +-----------+ Ctrl Endpt +---------+ | | | +-----------+ | +------------+ +-------+ | | Control |...........|..| ALG |.........|device | | | App | | +------------+ +-------+ | +-----------+ | | | | +-----------------------------------+ ]]> In , the onboarding app provides the device particulars. As part of the response, the SCIM server might provide additional information, especially in the case of non-IP devices, where an application-layer gateway may need to be used to communicate with the device. The control endpoint is one among a number of objects that may be returned.

Schema Description RFC 7643 does not prescribe a language to describe a schema. We have chosen the JSON schema language for this purpose. This implies that use of XML for this device extension is not supported. Several additional schemas specify specific onboarding mechanisms, such as BLE and Wifi Easy Connect.

Schema Representation Attributes defined in the device core schema and extensions comprise characteristics and SCIM datatypes defined in Sections 2.2 and 2.3 of the . This RFC does not define new characteristics and datatypes for the SCIM attributes.

Terminology The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14 when, and only when, they appear in all capitals, as shown here.

ResourceType Device This section defines a new resource type, 'Device'. The "ResourceType" schema specifies the metadata about a resource type (see section 6 of ). The resource "Devices" comprises a core device schema and several extension schemas. The core schema provides a minimal resource representation, whereas extension schemas extend the core schema depending on the device's capability. The JSON schema for Device resource type is in .

Common Attributes The Device schema contains three common attributes as defined in the . id An id is a required and unique attribute of the device core schema (see section 3.1 of ). externalID An externalID is an optional attribute (see section 3.1 of ). meta Meta is a complex attribute and is required (see section 3.1 of ).

SCIM Core Device Schema The core device schema provides the minimal representation of a resource "Device". It contains only those attributes that any device may need. Not all attributes are optional. The core schema for "Device" is identified using the schema URI: "urn:ietf:params:scim:schemas:core:2.0:Device". The following attributes are defined in the device core schema.

Singular Attributes deviceDisplayName This attribute is of type "string" and provides a human-readable name for a device. It is intended to be displayed to end-users and should be suitable for that purpose. The attribute is not required, and is not case-sensitive. The attribute may be modified and should be returned by default. No uniqueness constraints are imposed on this attribute. adminState The "adminState" attribute is of type "boolean" and is a mutable attribute. If set to TRUE, the commands such as connect, disconnect, subscribe that control app sends to the controller for the devices will be processed by the controller. If set to FALSE, any command coming from the control app for the device will be rejected by the controller. This attribute is required and mutable. The attribute should be returned by default and there is uniqueness contraint on the attribute. mudUrl The mudUrl attribute represents the URL to the MUD file associated with this device. This attribute is optional and mutable. The mudUrl value is case sensitive and not unique. When present, this attribute may be used as described in . This attribute is case sensitive and returned by default.

An example of a device SCIM object is as follows:

{ "schemas": ["urn:ietf:params:scim:schemas:core:2.0:Device"], "id": "e9e30dba-f08f-4109-8486-d5c6a3316111", "deviceDisplayName": "BLE Heart Monitor", "adminState": true, "meta": { "resourceType": "Device", "created": "2022-01-23T04:56:22Z", "lastModified": "2022-05-13T04:42:34Z", "version": "W\/\"a330bc54f0671c9\"", "location": "https://example.com/v2/Device/e9e30dba-f08f -4109-8486-d5c6a3316111" } }

Section .


Device Groups

Device groups are created using the SCIM groups as defined in
 Section 4.2.


Resource Type EndpointApp
This section defines a new resource type, 'EndpointApp'. The 
"ResourceType" schema specifies the metadata about a resource type 
(see section 6 of ). The resource "EndpointApp" represents
partner applications that can control and/or receive data from the
devices. The JSON schema for EndpointApp resource type is in .
The attributes comprising EndpointsApp are listed in .
The "EndpointApp" are included in the enpoint applications extension 
("endpointAppsExt") .


SCIM EndpointApp Schema
The schema for "EndpointApp" is identified using the schema URI:
"urn:ietf:params:scim:schemas:core:2.0:EndpointApp". The following
attributes are defined in this schema.

Common Attributes

The EndpointApp schema contains three common attributes as defined in the
.


Singular Attributes

applicationType

This attribute is of type "string" and represents the type of 
application. It will only contain two values; 'deviceControl' 
or 'telemetry'. 'deviceControl' is the application send commands
to control the device. 'telemetry' is the application that receives
data from the device. The attribute is required, and is not 
case-sensitive. The is attribute readOnly and should be returned 
by default. No uniqueness constraints are imposed on this attribute.

applicationName

The "applicationName" attribute is of type "string" and represents a
human readable name for the application. This attribute is required and
mutable. The attribute should be returned by default and there is no 
uniqueness contraint on the attribute.

client-token

This attribute type string contains a token that the client will use 
to authenticate itself.  Each token may be a string up to 500 
characters in length. It is mutable, required, case sensitive 
and returned by default if exists.


Complex Attribute

certificateInfo

It is the complex attribute that Contains x509 certificate's subject
name and root CA information associated with the device control or 
telemetry app. It further has three attributes that are described 
below.

rootCN

It is the root certificate common name. This attribute is required,
read only, singular and case sensitive.

subjectName

Also known as the Common Name (CN), the Subject Name is a field in the
X.509 certificate that identifies the primary domain or IP address for
which the certificate is issued. This attribute is not required,
read only, singular and case sensitive.

subjectAlternativeName

This attribute allows for the inclusion of multiple domain names and
IP addresses in a single certificate. This enables the certificate to
be used for multiple related domains or IPs without the need for 
separate certificates for each. This attribute is not required,
read only, multivalued and case sensitive.



Note that attributes client-token and certificateInfo are used for the
authentication of the application. Both SHALL NOT exist together in the
SCIM object. Either client-token or certificateInfo SHALL be present
in the SCIM object.

An example of a endpointApp SCIM object is as follows. Note that since
certificateInfo is present in the example, client-token attribute is 
NULL.

SCIM Device Extensions

SCIM provides various extension schemas, their attributes,
JSON representation, and example object. These schemas extend the core
device schema based on the device's capability (communication stack).
This RFC presents an additional hierarchical level by introducing
extensions within an extension.  See below for more details.

[[ DISCUSS: Is this okay with the working group? ]]

BLE Extension

This schema extends the device schema to represent the devices
supporting BLE. The extension is identified using the following 
schema URI:

urn:ietf:params:scim:schemas:extension:ble:2.0:Device

The attributes are as follows:

Singular Attributes

deviceMacAddress

A string vakue that represent a public MAC address assigned by the 
manufacturer. It is a unique  48-bit value. Ir is required, case 
insensitive, and it is mutable and return as default. The regex 
pattern is the following:



isRandom

A boolean flag taken from the BLE core specification, 5.3. If FALSE, the
device is using a public MAC address. If TRUE, the device uses a
Random address resolved using IRK. This attribute is not required, it is 
mutable, and returned by default.  Its default value is FALSE.

separateBroadcastaddress

When present, this address is used for broadcasts/advertisements.
This value MUST NOT be set when an IRK is provided.  Its form is the
same as deviceMacAddress.  It is not required, multivalued, mutable,
and returned by default.

irk

A string value, Identity resolving key, which is unique for every 
device. It is used to resolve the random address. It is required when 
addressType is TRUE. It is mutable and return by default.


Multivalued Attributes

versionSupport

A multivalued attribute that provides all the BLE versions supported by the
device in the form of an array. For example, 
[4.1, 4.2, 5.0, 5.1, 5.2, 5.3]. It is required, mutable, and 
return as default.

pairingMethods

An array of pairing methods associated with the BLE
device. The pairing methods may require sub-attributes, such as
key/password, for the device pairing process. To enable the
scalability of pairing methods in the future, they are represented as
extensions to incorporate various attributes that are part of the
respective pairing process. Pairing method extensions are nested
inside the BLE extension. It is required, case sensitive, mutable, and 
returned by deafult.


BLE Pairing Method Extensions

The details on pairing methods and their associated attributes are in
section 2.3 of .  This memo defines extensions for four
pairing methods that are nested insided the BLE extension schema. Each 
extension contains the common attributes . These 
extension are are as follows.

(i) pairingNull extension is identified using the following schema URI:

urn:ietf:params:scim:schemas:extension:pairingNull:2.0:Device

pairingNull does not have any attribute. It allows pairing for BLE
devices that do not require a pairing method.

(ii) pairingJustWorks extension is identified using the following 
schema URI:

urn:ietf:params:scim:schemas:extension:pairingJustWorks:2.0:Device

Just works pairing method does not require a key to pair devices. For
completeness, the key attribute is included and is set to 'null'. Key 
attribute is required, immutable, and return by default.

(iii) pairingPassKey extension is identified using the following 
schema URI:

urn:ietf:params:scim:schemas:extension:pairingPassKey:2.0:Device

The pass key pairing method requires a 6-digit key to pair devices.
This extension has one singular integer attribute, "key", which is 
required, mutable and returned by default. The key pattern is
as follows:



(iv) pairingOOB extension is identified using the following 
schema URI:

urn:ietf:params:scim:schemas:extension:pairingOOB:2.0:Device

The out-of-band pairing method includes three singular attributes,
i.e., key, randomNumber, and confirmationNumber.

key  The key is string value, required and received from out-of-bond 
sources such as NFC. It is case sensitive, mutable, and returned 
by default.

randomNumber  It represents a nounce added to the key. It is and 
integer value that is required attribute. It is mutable and 
returned by default.

confirmationNumber  An integer which some solutions require in RESTful
message exchange. It is not required. It is mutable and returned by 
default if it exists.

The Endpoint Applications Extension Schema

Sometimes non-IP devices such as those using BLE or Zigbee require an
application gateway interface to manage them. SCIM clients MUST NOT
specify this to describe native IP-based devices.

endpointAppsExt provides the list application that connect to 
enterprise gateway. The endpointAppsExt has one multivalued attribute 
and two singular attributes. The extension is identified using the
following schema URI:

urn:ietf:params:scim:schemas:extension:endpointAppsExt:2.0:Device

Singular Attributes

DeviceControlEnterpriseEndpoint

Device control apps use this URL of the enterprise endpoint to reach
the enterprise gateway. When the enterprise receives the SCIM object from
the onboarding app, it adds this attribute to it and sends it back as
a response to the onboarding app. This attribute is required,
case-sensitive, mutable, and returned by default. The uniqueness is
enforced by the enterprise.

telemetryEnterpriseEndpoint

Telemetry apps use this URL of the enterprise endpoint to reach
the enterprise gateway. When the enterprise receives the SCIM object from
the onboarding app, it adds this attribute to it and sends it back as
a response to the onboarding app. This attribute is required,
case-sensitive, mutable, and returned by default. The uniqueness is
enforced by the enterprise.


Multivalued Attribute

applications

This is a complex multivalued attribute. It represents a list of 
endpoint applications i.e., deviceControl and telemetry. Each entry in
the list comprises two attributes including "value" and "$ref".

value

It is the identifier of the endpoint application formated as UUID. It
is same as the common attribute "$id" of the resource "endpointApp".
It is readOnly, required, case insensitive and returned by default.

$ref

It is the reference to the respective endpointApp resource object 
stored in the SCIM server. It is readOnly, required, case sensitive
and returned by default.

The following sections provide representations of schemas for both
   SCIM resources and service provider schemas.  Note that the JSON
   representation has been modified for readability and to fit the
   specification format.

8.7.1.  Resource Schema Representation

The following is intended as an example of the SCIM schema
   representation in JSON format for SCIM resources.  Where permitted,
   individual values and schema MAY change.  This example includes
   schema representations for "User", "Group", and "EnterpriseUser";
   other schema representations are possible.



Security Considerations

Because provisioning operations are senstive, each client must be
appropriately authenticated.  Certain objects may be read-only or
not visible based on who is connected.

[ More to be added here. ]


IANA Considerations
