阐述通信保密的三个环节——信源保护,消息保护,信号保护,三类措施——防范措施,躲避措施,抵抗措施;三种手段——技术手段,管理手段,行政手段。作者认为,通信保密链路是一个整体,任何环节都不能出庇漏;各类措施应相互配合以增强保密能力。作者还认为,当前,以技术手段实现的消息保护(抗破译)应做为我们考虑通信安全的重点。现在,对通信保密的含意、重点、实现等的理解不尽一致,作者提出这些看法供读者参考。
Describe the three aspects of communication confidentiality - source protection, message protection, signal protection, three types of measures - preventive measures, avoidance measures, resistance measures; three kinds of means - technical means, management tools, administrative means. The author believes that the communication confidential link is an integral part of any link can not be out of date; various measures should cooperate with each other to enhance confidentiality. The author also believes that at present, the message protection (anti-deciphering) realized by technical means should be the focus of our consideration of communication security. Now, the understanding of the meaning, focus and realization of communication secrecy is not consistent. The author puts forward these views for readers’ reference.
