| 摘 要： | 在WAP的WTLS层中，通过HASH函数实现的消息验证码可以保证数据传输时的完整性，这样可以有效地防止数据在传输过程中被主动攻击者修改，也可以防止数据被重放攻击性和拒绝服务攻击。叙述了HMAC中SHA-1及MD5算法的实现，重点分析了这2种算法各自的优越性。

| Abstract: | The integrity of data in WAP's WTLS 1ayer is implemented by MAC with HASH function. In this way the transmitting data to be inserted, modified and registered can be efficiently protected, and attacks or denial-of-service attack to be launched by active attacker can be avoided. This paper describes the implementation of SHA-1 and MD5 in HMAC, and analyzes the superiority of the two algorithms. |
