摘要
针对现有无线传感器网络基于ECC认证协议签名验证过程计算量巨大的缺陷,文章提出一种基于批处理验证的异构无线传感器网络认证协议。该协议根据传感器网络的异构特性,利用公钥签名算法ECDSA对消息进行签名,验证签名时采用联合稀疏系数方法。仿真实验表明,该协议有效地降低了批处理验证中多标量乘运算的计算量,大大提高了数字签名的验证效率。
To the question that verification protocol based on ECC of WSN requires huge computational,an authentication protocol based on batch verification for heterogeneous WSN is proposed.Considering the heterogeneous characteristics of WSN,the protocol uses ECDSA to sign messages and takes joint sparse coefficient to verify signatures.Simulation analysis shows that the protocol can reduce the computational complexity of multi-scalar multiplications in batch verification effectively,and the efficiency of digital signature verification is improved greatly.
