摘　　要：为了提高合法用户在无线传感器网络(wireless sensor networks,WSNs)中访问节点数据时的安全性,基于已有的动态认证协议和Das协议,提出了一种混合Das协议的WSNs身份验证协议(MDas)。该协议具有动态认证协议通过单向散列函数和异或运算来实现加密/解密的性能,也具有Das协议采用唯一的智能卡进行身份验证的特点。相比Das协议和动态认证协议,MDas协议增加了密码变更阶段,并且在协议的验证阶段增加了登录节点与传感器节点之间的互相验证操作,加强了身份验证的安全性。安全特性对比和计算成本分析结果表明,MDas协议可以抵御伪装网关重放攻击、伪装登陆节点攻击以及蛮力攻击,具有更好的安全性能。In order to improve the security of legitimate user access to the node data in the wireless sensor networks （WSNs）,an authentication protocol hybrid Das protocol for wireless sensor networks was proposed.This protocol has a dynamic authentication protocol by one-way hash function and XOR operation to achieve the encryption/decryption performance,and it also has a characteristic that Das protocol using only a smart card to authenticate.Compared with Das protocol and dynamic authentication protocol,MDas protocol increases the password change phase,and also increases the mutual verification operation between the login node and sensor nodes during the verification phase of the agreement to enhance the authentication security.The analysis on protocol security features comparison and calculation cost showed that the MDas protocol can resist the attack of camouflage gateway replay,and it has the better security performance.
