使用预计算密码进行旁信道攻击保护的认证方法和系统

描述了一种认证系统和一种用于使用密码进行认证的方法的实施例。在所述系统和方法中，在确定为安全的环境中，在基站处执行加密算法的加密计算，来产生用于后续认证过程的预计算密码。所述预计算密码随后被用于从所述基站发射认证请求消息并用于验证认证响应消息，以用于所述后续认证。 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.
