摘　　要：简要分析了4步握手协议的漏洞,指出4步握手协议在面对DOS攻击时是脆弱的,提出了2步握手协议的握手方法。该协议采用序列数代替4步握手协议中的随机数,将4步握手协议中4次信息交换减少为2次,提高了协议的安全性和效率,对2步握手协议的安全性进行了分析。对2步握手协议在快速切换中应用的安全性和性能进行了分析,并与4步握手协议性能进行比较,比较结果表明了该协议在性能和安全性方面都优于4步握手协议。The loopholes of the 4-way handshake protocol are analyzed, and the shortcoming is pointed out that the protocal is weak when it is attacked by denial of service, so a new protocol called the 2-way handshake is proposed. The protocol uses sequence number instead of random number adopted in the 4-way handshake protocol, and also reduces the messages transmit from 4 times in the 4-way handshake protocol to 2 times in the 2-way handshake protocol, the protocol security is enhanced and the efficiency is improved, then the protocol security problem is analyzed. At last the security and performance problems of the protocol are also analyzed in application of the fast handover mechanism, from comparing 2-way handshake protocol with 4-way handshake protocol in the application of fast handover mechanism, the 2-way handshake protocol proved tobe more secure and efficient.
