泛在电力物联网的多项式密钥管理算法研究

Research on polynomial keymanagement algorithm ubiquitous in power Internet of Things

随着泛在电力物联网(UPIOT)的快速发展,其传感器网络出现的安全问题也广受关注。本文针对在国家电网、安全监控等关键领域中密钥管理技术进行了研究。虽然RSA和椭圆曲线等公钥加密方案能够提供足够的安全性,但由于计算量大,与传感器节点的资源约束相冲突,使得它们的使用受到了限制。对于集群密钥的安全管理方面,本文将双变量多项式的概念引入密钥管理。这不仅仅确保了任意两个节点之间的成对密钥,还对生成的双变量多项式进行簇间密钥分配,对生成的双变量多项式在密钥管理中的各种特性进行测试,并在多项式的不同阶数下进行了仿真实验及结果分析。

With the rapid development of the ubiquitous Power Internet of Things(UPIOT),the security problems of its sensor networks are also widely concerned.Traditional sensor networks are composed of hundreds of self-organizing sensor nodes.Key management is one of the most important security primitives in state grid,security monitoring and so on.Although public key encryption schemes such as RSA and elliptic curve can provide sufficient security,their use is limited due to the large amount of computation and the conflict with the resource constraints of sensor nodes.For the security management of cluster keys,this paper introduces the concept of bivariate polynomial into key management.This not only ensures the pair key between any two nodes,also for key distribution between the clusters of the bivariate polynomial,and finally to generate various features in the key management of bivariate polynomial test.Under different order polynomial,the simulation experiment and the simulation results are analyzed.
