| Abstract: | Recognizing and dealing with covert channel is the key requirement of TCSEC to evaluate the B2 or above products,as well as the key requirement of international standard CC to evaluate the EAL5 or above products.Now covert channel analysis is the main bottleneck of development of security information system with high security level.Based on the secure OS(SLinux) designing and implementing,this paper emphasis describes the identification processing,mainstream methods,bandwidth computation and analysis report of covert channel.It can give important edification on advanced secure information system research. |
