当前,卫星网络密钥管理方案复杂度的度量以理论分析为主,缺乏对其执行效率的有效评估手段.为此,文中在OpenSSL及Miracl等密码库的基础上,通过引入时延、误码率、丢包率等算法,设计了卫星网络密钥管理方案仿真平台,并进行了性能测试及相关方案仿真.结果表明:构建的仿真平台具有良好的可扩展性,基本链路参数可满足实际密钥管理方案的运行要求.另外,ID-KMS方案仿真结果也验证了基本链路参数算法的有效性,说明了该仿真平台可为后续密钥管理方案的执行效率评估提供实验环境支撑.%Currently, the measurements of complexity are mostly based on theoretical analysis, lacking of effective evaluation of their practical performance. As a result, a simulation platform for the efficiency of key management of satellite network is designed and implemented in this paper. The algorithm of delay,bit error rate and packet loss rate are applied in the process of implementation based on the OpenSSL and Mircal. The performance test of the platform and the simulation of some key management schemes are also presented. Experiment results demonstrate the platform is of good expansibility,which can fulfill the practical demand of key management scheme. Moreover,the simulation results of ID-KMS not only confirm the validity of basic link parameter algorithm,but also show that this platform could be applied to improve the experiment condition.
