Abstract
Official abstract text for this publication.
A challenge manipulation and restoration capability is provided for use during network authentication. A mobile device (MD) and a subscriber server (SS) each have provisioned therein a binding key (B-KEY) that is associated with a subscriber identity of a network authentication module (NAM) of the MD. The SS obtains an authentication vector (AV) in response to a request from a Radio Access Network (RAN) when the MD attempts to attach to the RAN. The AV includes an original authentication challenge parameter (ACP). The SS encrypts the original ACP based on its B-KEY, and updates the AV by replacing the original ACP with the encrypted ACP. The MD receives the encrypted ACP, and decrypts the encrypted ACP based on its B-KEY to recover the original ACP. The MD provides the original ACP to the NAM for use in computing an authentication response for validation by the RAN.
First claim
Opening claim text (preview).
What is claimed is: 1. An apparatus, comprising: a processor and a memory communicatively connected to the processor, the processor configured to: receive an equipment identity of a mobile device and a subscriber identity associated with a network authentication module of the mobile device; determine, based on the subscriber identity associated with the network authentication module of the mobile device and the equipment identity of the mobile device, whether the network authen…
