Extraction of Synchronous Computer Compromising Emanation Information Based on DSP

针对计算机行同步信号产生的泄露发射信息问题,提出一种提取该信息的相关检测算法,介绍利用Matlab仿真软件模拟提取行同步的策略,给出该算法在数字信号处理上的具体实现过程。在ICETEK-C6713-A EVM实验平台上进行同步信息截取实验,结果证明该方法具有较好的鲁棒性。

According to the problem of compromising emanation information caused by horizontal synchronous computer signal, this paper presents a correlative detection algorithm for extracting the information, and introduces a strategy of extracting synchronous information with Matlab simulation. The implementation of the algorithm on Digital Signal Processing（DSP） is given, and the experiment is performed on the ICETEK- C6713-A EVM platform, whose results prove the robustness of the method.
