基于OpenSSL库的椭圆曲线密码体制的OMNeT++实现

摘要

简要阐述了适用于物联网的密码体系,介绍了ECDSA和ECDH算法,着重解释了OMNet++网络仿真软件和OpenSSl密码库的一些与ECDSA和ECDH算法相关的函数接口,并在OMNeT++平台上测试了ECDSA和ECDH算法的耗时性能.测试结果表明,ECDSA和ECDH算法在时间消耗上完全适用与当前主流移动终端.%This paper briefly represent suitable cryptosystem for the Internet of Things, and carry on an introduction to Elliptic Curve Digital Signature Algorithm (ECDSA) and Elliptic Curve Diffie-Hellman(ECDH). After that, this paper expounds a network simulation framework named OMNeT-H- (Objective Modular Network Testbed in C++) and some function interfaces related to ECDSA and ECDH in OpenSSL. Finally ,this article takes some experiments in OMNeT++ to test the time consuming of ECDSA and ECDH. The analysis result indicates that ECDSA and ECDH are completely suitable for main current mobile terminal in time consuming.
