摘　　要：分析了当今遥科学信息系统中存在的一系列安全隐患 ,及时提出安全遥科学的基本框架 ,并从密码学角度提出了若干对策和建议。其次 ,着重研究怎样保护基于CCSDS高级在轨系统的空间通信链路免受非法第三方攻击的情形 :为遥科学信息传输系统提出传统密码与公钥密码相结合、保密性与身份认证相统一的高强度密码方案和一种快速算法 ,在一定程度上将减轻制约遥科学发展的”瓶颈”By analyzing a series of hidden security dangers in contemporary telescience information systems, a basic frame of secure telescience is depicted in time and some countermeasures and suggestions from a cryptographic perspective are presented. How to prevent the special case that an illegal party attacks telescience space communication links based on CCSDS. AOS is also dealt with. Combined with conventional cipher and public-key cipher and unified with confidentiality and authentication, a strong cryptographic scheme and a fast algorithm are given for telescience information transmission systems, which can simultaneously relieve to some extent the bottleneck problem (delay) restricting the development of telescience.
