摘要
针对空间通信环境的信道暴露、覆盖范围大以及带宽资源有限等问题,分析比较对称加密与非对称加密2类典型的传统数据加密算法的优缺点,将2类算法混合使用后,对其可行性作分析,设计一种保证空间数据安全传输的数据保护策略。研究结果表明,该策略具有较好的可行性。
According to the space communications＇ especial environment such as the exposed channel,the large coverage area and the limited bandwidth resources,this paper analyzes and compares the advantages and disadvantages of two types of conventional data encryption algorithm,symmetric encryption and asymmetric encryption.After mixing the two types of algorithms and making a brief analysis of the feasibility,a data protection strategy is designed to ensure that the space data can be transmitted in security.Theoretical analysis and simulation results show that the proposed strategy is fairly practical.
