摘要
通过分析文献[1]中Wang提出的一个匿名移动无线认证方案中的Hand-Off认证协议,发现了其存在安全漏洞,无法抵抗中间人发起的重放攻击,针对该协议存在的安全漏洞对原协议进行了改进,改进后的协议可以安全的实现用户与机站之间的身份认证,并可以有效地抵抗中间人发起的重放攻击。
By analysing the security of an anonymous wireless authentication scheme mentioned in article [1] by Wang, the hand-off authentication protocol is pointed out in that scheme can not against reset attacks initiate by men-in-the-middle. An improved protocols to overcome the weakness is proposed. The improved protocols can not only securely realize identify authentication between the user and the base station but also efficient against reset attacks.
