Covert Channel and Identification Methods

Abstract

Abstract: When developing a secure system at or above B2, it needs covert channel analysis by TCSEC. This paper introduces the definition and classification of covert channel, compares with the advantages and drawbacks of present covert channel identification, and proposes the Richard's shared resource matrix method in detail.

摘要： 根据TCSEC规定，开发B2及以上安全系统时必须进行隐通道分析，该文简要介绍了隐通道的概念及分类，并在比较现有隐通道搜索方法优缺点的基础上，详细给出了共享资源矩阵法的隐通道分析操作步骤。
