摘要
广播认证是无线传感器网络(Wireless Sensor Networks,WSN)的1种基本安全服务,针对现有认证方案的计算量大、认证速度慢等问题,提出1种基于椭圆曲线加密(Elliptic Curve Cryptography,ECC)和身份(ID)签名的WSN广播快速安全认证方案。对现有EIBAS签名认证方案进行改进,通过节点间的合作,共享中间计算结果来减少邻居节点的计算量,以此提高认证速度,减少能量消耗。同时,提出1种安全机制,通过对多个邻居共享数据的对比来抵御恶意节点的攻击。实验结果表明,该方案能够提高约42%的签名认证速度,降低约36%的能耗,大大延长了网络生命周期。
The broadcast authentication is a fundamental security service in wireless sensor network （WSN）. For the issues that the existing authentication schemes have the disadvantages such as large amount of calculation, slow authentication and so on, a fast authentication scheme of WSN broadcast based on ECC and ID signature is proposed. The scheme is an improvement of the existing EIBAS signature authentication scheme. In this scheme, the calculation amount of neighbor nodes is reduced through sharing intermediate computing results between nodes, in order to improve the speed of certification and reduce energy consumption. At the same time, a security mechanism is proposed to resist the attack of the malicious nodes by comparing the data from the multiple neighbors. Experimental results show that the proposed scheme can improve the speed of signature verification by about 42 %, and reduce the energy consumption by about 36 %, which greatly prolongs the network life cycle.
