双向认证的方法、系统及装置
摘要：
本发明提出一种双向认证的方法、系统及装置。该方法包括：网络实体获取ME新的三元组向量；网络实体根据所述三元组向量生成输出参数，并将所述输出参数发送给ME，其中，输出参数由随机数RAND和认证执行次数CNR加密形成；ME对输出参数进行解密，并根据解密结果对网络进行认证，同时由ME的用户身份模块SIM卡生成RES，并将生成的所述RES发送给所述网络实体；网络实体根据接收的所述RES对所述ME进行认证。采用本发明可以实现ME和网络侧之间的双向认证，并且可以在受到重放攻击时判断为ME认证网络不通过。
摘要（英）：

The invention provides a method, a system and a device for mutual authentication. The method comprises: a network entity obtains the new triplet vector of mobile equipment (ME); according to the triplet vector, the network entity generates an output parameter and sends the output parameter to the ME, wherein the output parameter is formed by encrypting random number RAND and authentication execution time CNR; the ME decrypts the output parameter and authenticates the network according to a decrypting result; meanwhile, the a subscriber identity module (SIM) card of the ME generates an RES and sends the generated RES to the network entity; and the network entity authenticates the ME according to the received RES. The invention can realize mutual authentication between ME and the network side and can judge that ME authenticates the network not to pass when suffering replay attack.
