Facilitating authentication of access terminal identity

摘要

Methods and apparatuses are provided for facilitating authentication of access terminal identities and for recording a usage relationship between a valid access terminal identity and a user identity. An access terminal and a validation server are both provisioned with corresponding validation keys. The access terminal may determine that a user identity is not recorded for use with the access terminal, and may send a report message to report a usage relationship between the access terminal identity and the user identity, where the report message is signed with a signature based on the validation key. The validation server authenticates the signature using the validation key in the validation server. The validation server may record the usage relationship between the authenticated access terminal identity and the user identity in a database, which database records may be employed to determine whether an access terminal requesting network access is authorized or unauthorized.

主权项

1. An access terminal, comprising:
a communications interface adapted to facilitate wireless communications; a user identity module including a user identity; a storage medium including a validation key from an authorized vendor of the access terminal and an access terminal identity stored therein; and a processing circuit coupled to the communications interface, the user identity module, and the storage medium, the processing circuit adapted to:
determine that the user identity from the user identity module is not recorded for use with the access terminal;generate a report message including the user identity and the access terminal identity, the report message adapted to report, to a validation server, a usage relationship between the user identity and the access terminal identity;sign the report message that reports the usage relationship between the user identity and the access terminal identity with a signature that is generated based on the validation key, wherein the signature is adapted to authenticate that the access terminal is authorized to use the access terminal identity included in the report message; andsend a transmission including the signed report message via the communications interface.
