| 摘 要： | 对认证与密钥协商协议( UMTS AKA)中无和有序列号SQN进行了3种攻击场景模拟并得到结论：SQN的使用不能有效抵抗重放攻击。基于此，进一步分析并仿真了使用一次性随机数抵抗重放攻击的3种改进协议，结果表明：AP-AKA和基于公钥密码学的AKA能够有效抵抗重放攻击，但是AP-AKA增加了实体的存储和计算资源，基于公钥密码学的AKA增加了算法的复杂性，而S-AKA只能部分抵抗重放攻击。

| Abstract: | Three types of attacks ' scenarios were described when there exists or not sequence number ( SQN) in UMTS AKA. Analysis shows that the use of SQN cannot resist replay attacks effectively. Based on that, three new protocols using one-time random number were further analyzed and simulated to resist replay attacks. It is shown that AP-AKA and AKA based on public key cryptography can effectively a-gainst replay attacks. However, AP-AKA will add storage and computing resources of entities and AKA based on public key cryptography promotes the complexity of algorithm, but S-AKA only keeps against re-play attacks partially. |
