Secure wireless communication

摘要

In one embodiment, the method performed by mobile equipment to authenticate communication with a network includes generating keys using cellular authentication and voice encryption, and then generating an authentication key based on these keys. The authentication key is used to generate an expected message authentication code used in authenticating the network according to authentication and key agreement security protocol.

1. A device, comprising:
a mobile equipment configured to,
receive authentication information from a network,obtain a first random number from the received authentication information, the first random number being a random number that the mobile equipment had sent the network,generate at least one mobile equipment key based on the first random number using cellular authentication and voice encryption,obtain a second random number from the received authentication information, the second random number being associated with the network,generate at least one network key from the second random number using the cellular authentication and voice encryption,generate an authentication key that includes hashing together the mobile equipment key and the network key,generate an expected network message authentication code based on the authentication key and at least a portion of the received authentication information according to authentication and key agreement security protocol, andauthenticate the network based on the expected network message authentication code.
