无线传感器网络中三方密钥建立协议研究

提出了一个无线传感器网络(WSN)的可证明安全认证三方密钥建立协议。协议的安全性基于求解椭圆曲线离散对数问题和双线性配对Diffie Hellman问题的计算不可行性。节点之间的身份验证是无线传感器网络中最具挑战性的一个安全要求，它需要在WSN中三个相邻节点之间建立正确的会话密钥轮来实现这种安全目标。通过理论证明,该协议对数据完整性攻击和会话密钥中已知密钥安全性攻击是安全的，并提供了完美的前向安全。

Research on tripartite key establishment protocol for wireless sensor networks

A provably secure authenticated multiple key establishment protocol for Wireless Sensor Networks (WSNs) is proposed.Security of the protocol is based on the computational infeasibility of solving elliptic curve discrete logarithm problem and computational Diffie Hellman problem on bilinear pairing.The authentication among the nodes is one of the most challenging security requirements in WSNs.To achieve this security goal, it is required to establish a correct session key among the three adjacent nodes of WSNs. It is proved that the proposed protocol is secure against the attacks on data integrity and the known key security attacks on session key.It also provides perfect forward secrecy.
