采用时域以及时、频二维置乱体制,使二线全双工成为有线模拟保密通信的一大技术难题。本文第一部份扼要介绍了国外解决此问题的四种方法。开发微处理器以及单片微机在模拟保密技术中的应用,必能提高模拟保密机的性能,降低成本,缩小体积,增强功能。因此,开展此项工作成为引人注目的课题。本文第二部份简要说明了微处理器以及单片微机在国外模拟技术中的主要应用,比较详细地阐述了时域置乱的单片机实现。
The use of time-domain and frequency, frequency and two-dimensional scrambling system, so that second-line full-duplex cable to become a simulation of confidential communications a major technical problems. The first part of this article outlines four ways to solve this problem abroad. Development of microprocessors and single-chip microcomputer in the simulation of security technology, will be able to improve simulation security machine performance, reduce costs, reduce size and enhance functionality. Therefore, to carry out this work has become an attractive topic. The second part of this article briefly describes the main applications of microprocessors and single-chip microcomputers in foreign simulation technology, and expounds the SCM implementation in time-domain scramble.
