This paper gives one static analysis-based behavior model building method for trusted computing dynamic verification, including control flow graph （CFG） building, finite state automata （FSA） constructing, e run cycle removing, e transition removing, deterministic finite state （DFA） constructing, trivial FSA removing, and global push down automata （PDA） constructing. According to experiment, this model built is a reduced model for dynamic verification and covers all possible paths, because it is based on binary file static analysis.展开更多

On the leading edge of treads, on-demand, high-reliability, and low-latency routing protocol is desirable for indoor environment applications. This article proposes a routing scheme called robust multi-path routing that establishes and uses multiple node-disjoint routes. Providing multiple routes helps to reduce the route recovery process and control the message overhead. The performance comparison of this protocol with dynamic source routing （DSR） by OPNET simulations shows that this protocol is able to achieve a remarkable improvement in the packet delivery ratio and average end-to-end delay.展开更多
