安全与认证问题一直是无线传感器网络所面临的棘手难题之一,尤其是在有敌意的环境中。针对无线传感器网络通信内容易被窃听和篡改的问题,提出了一种基于 Hopfield 神经网络(HNN)的密钥共享协议。该协议通过利用 HNN 的收敛特性,在任意两个节点之间建立安全通信所需的共享密钥,同时将密钥量化为 i 位字符串以防止暴力破解攻击。最后实例化验证了此方案的有效性。

Security and authentication have been one of thorny problems in wireless sensor networks,especially in a hostile environment. Aiming at the problem of eavesdropping and tampering with the contents in wireless sensor network communication, a secret key sharing protocol based on Hopfield neural network(HNN)is proposed. By using the convergence characteristics of HNN,the sharing secret key needed by safety communication is established between any two nodes,in which the key is quantified into i?bit character string to prevent brute force attack. The effectiveness of the scheme is proved by instantiation.
