After defining two ideas lattice and convert channel, this paper analyses detecting methods of convert channel including SRM, syntactic information flow analysis, semantic information flow approach and non-interference method. This paper put forwards one method of improved syntactic information flow processing. The idea in this kind of method is that we design PC to sign every row of program, and...
From the three basic character of the computer security: confidentiality, integrity, availability, the paper studies the Bell-Lapadula confidentiality model, the Biba integrity model, the Clark-Wilson integrity model and Chinese wall Model. This paper also studies the relation among three models of the Bell-Lapadula model, the Biba model and he Clark-Wilson model, studies the relation and distinguishes...
On the basis of analyzing static routing algorithm and dynamic routing algorithms, this paper focus on the link state routing of the dynamic routing algorithm, puts forward a more concise routing way in the link state routing. Dijkstra routing algorithm is suitable for calculating the shortest path from one router to other routers, but there are more point-to-point links in the computer network, Floyd...
