By introducing three kinds of belief operators into ATEL,a new multi-agent cooperation logic named ATBKL (Alternating-time Temporal Belief and Knowledge Logic) was developed. A model checking algorithm was proposed. It is proved that the model checking complexity of ATBKL is the same as that of ATEL,i.e.,the presented logic is better for further study of multi-agent systems.展开更多

The correctness of security protocols is of vital importance to ensure the security of the Inter-net application. Formal methods have been proved to be a valid approach to analyze and verify security protocols. Thispaper briefly introduces the three main styles in the field of security protocol analysis and their representative work.After that,it points out the future deveopment direction.展开更多
