一种新的网络信息聚合签名方法的仿真研究

Simulation Research on a New Network Information Aggregation Signature Method

现有研究提出的网络信息签名方法忽略了对信息签名间关联性的分析,导致签名信息的聚合成功率低,且误差率高。提出基于SM2密码算法的网络信息聚合签名方法。在SM2密码算法的基础上设计环签名方案,通过单向函数获得网络信息的签名算法,并对该签名方案安全性验证。采用动态时间弯曲方法度量网络信息签名之间存在的总体距离,构建网络信息签名之间的分量近似距离矩阵和总体距离矩阵,并从以上两个角度分析网络信息签名之间存在的关联关系,完成网络信息聚合签名。仿真结果表明,所提方法的签名信息聚合成功率高、误差率低,所提方法的实用性较好。

At present,some methods ignore the analysis for the correlation among information signatures,resulting in a low success rate and a high error rate in aggregating signature information.Therefore,a method of aggregating the network information signatures based on the SM2 cryptographic algorithm was put forward.At first,a scheme of ring signature was designed based on the SM2 cryptographic algorithm.Secondly,the one-way functions were adopted to get the signature algorithm of network information,and then the security of the signature scheme was verified.The dynamic time warping algorithm was used to measure the total distance between network information signatures,and thus to construct the matrix of component approximate distance and the matrix of the total distance between network information signatures.Moreover,the association relationship between network information signatures was analyzed respectively.Finally,we completed the aggregation of network information signature.Simulation results prove that the proposed method has a high success rate and low error rate in aggregating signature information,with better practicality.
