WSNs中基于Chebyshev多项式的可认证密钥协商方案

An Authenticated Key Agreement Scheme Based on Chebyshev Polynomials in WSNs

无线传感器网络中节点之间的通信在整个网络中有着重要地位,其安全性也逐渐受到关注.本文基于Chebyshev多项式提出了一种节点之间可认证的非对称密钥协商方案,利用Chebyshev多项式的半群特性和计算上的单向性设计会话密钥机制完成节点之间的认证功能,分析结果表明本文方案可以抵御无线传感网中的典型攻击.

Communication between nodes play an important role in the wireless sensor network, its security is also receiving attention gradually.An asymmetric authenticated key agreement based on Chebyshev polynomial between sensor nodes was proposed in this paper. Our schema designed by the semi-group property and the one-way trapped characteristic of Chebyshev polynomial. The analytical results show that：the proposed scheme can resist the typical attacks in wireless sensor network.
