Abstract
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.
Claims19
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, and
- authenticate the network based on the expected network message authentication code.

A node, comprising:
- a network node, configured to,
- generate a challenge including a sequence number field, an authentication management field, and a random number field, the sequence number field including a sequence number and a portion of a first random number the network node had received from a mobile equipment, the authentication management field including another portion of the first random number, and the random number field includes a second random number and a further portion of the first random number,
- obtain at least one mobile equipment key using the first random number,
- obtain at least one network key using a second random number,
- generate an authentication key that includes hashing together the mobile equipment key and the network key,
- generate a first message authentication code based on the authentication key according to authentication and key agreement security protocol,
- generate an authentication token based on the sequence number in the sequence number field, the authentication management field and the first message authentication code, and
- send the challenge and the authentication token to the mobile equipment.
