    Abstract: The present invention concerns a personal token for a mobile terminal in a communication network including an authentication server and a secure server producing derived key material on the basis of a random and a secret key (K) for use in an authentification and key agreement (AKA) procedure in a third-generation mobile system, said personal token including program instructions for re-computing the derived key material (Ck, Ik) on the basis of the received random and the secret key (K) as stored in the personal token, characterized in that the personal token includes program instructions for using a re-computed part of the derived key material in order to interpret the received additional data. This modification of the standard AKA procedure allows the personal token to keep the key material unavailable to the mobile terminal.

    Abstract translation: 本发明涉及用于通信网络中的移动终端的个人令牌，其包括认证服务器和安全服务器，其基于用于认证和密钥协商（AKA）中的随机和秘密密钥（K）来生成派生密钥材料 ）程序，所述个人令牌包括基于存储在个人令牌中的所接收的随机和秘密密钥（K）重新计算导出的密钥资料（Ck，Ik）的程序指令， 其特征在于，个人令牌包括用于使用所导出的密钥材料的重新计算的部分以便解释所接收的附加数据的程序指令。 标准AKA程序的这种修改允许个人令牌保持移动终端的密钥材料不可用。

    Abstract: Method of authentication in a system comprising two entities communicating between themselves by way of a network, a first entity (CARD) authenticating a second one (SERVER) and data received from said second entity, each entity storing the same secret key K, said first entity receiving a message authenticating code (MAC) and other parameters (RAND, SQN, AMF, ...), the message authenticating code calculation including the key K and said other parameters (RAND, SQN, AMF, ...), the authentication procedure consisting in challenging the received code (MAC) and an expected code (XMAC), the expected code being computed in using the received parameters and the key K stored in said first entity, characterized in that each time the two codes (MAC, XMAC) don't match, the authentication procedure is aborted, a failure counter storing the number of occurrences of abortion.
