This is the management module of the Secure Device Identifier (DevID) for managing IEEE 802.1AR. As specified in the current IEEE 802.1AR draft document. This is the management module of the Secure Device Identifier (DevID) for managing IEEE 802.1AR. A DevID is cryptographically bound to a device, and supports authentication of the device's identity. Locally significant identities can be securely associated with an initial manufacturer-provisioned DevID and used in provisioning and authentication protocols to allow a network administrator to establish the trustworthiness of a device and select appropriate policies for transmission and reception of data and control protocols to and from the device. A device indicates any entity in an IEEE 802 LAN that seeks to obtain services from the network. The use of a Secure Device Identifier (DevID) in a DevID module allows network entities to associate a DevID credential with devices that participate or wish to participate in authenticated access to one or more networks. A device with DevID capability incorporates a globally unique manufacturer provided Initial SecureDevice Identifier (IDevID), stored in a way that ensures it will remain unmodified in the absence of both unrestricted access to the device and extraordinary efforts by an attacker. The device may support the creation of Locally Signification Device Identifiers (LDevIDs) by network administrator. Each LDevID is bound to the device in a way that makes it impossible for it to be forged or transferred to a device with a different IDevID without knowledge of the private key used to effect the crytographic binding. LDevID can incorporate, and fully protect, additional information specified by the network administrator to support local authorization conventions. LDevIDs may also be used to entirely replace IDevIDs in such a way as to assure the privacy of the user of a LDevID and the equipment in which it is installed. Every device has exactly one (IDevID) and zero or more LDevIDs. The number of LDevIDs depends upon the capabilities of the DevID module and on the administrative policy of the network(s) in which the device is used
