Abstract
Embodiments of an authentication system and a method for authentication using ciphers are described. In the system and method, cryptographic calculations of an encryption algorithm are executed at a base station, in a determined secure environment, to produce a pre-calculated cipher for a subsequent authentication process. The pre-calculated cipher is then used to transmit an authentication request message from the base station and validation of an authentication response message for the subsequent authentication.
