Abstract
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.
