Such unknowns make it possible for seemingly long-gone data to turn up in a court under the order of a subpoena, or worse, in the hands of a hacker. On August 13th, though, a team of computer scientists led by Roxana Geambasu of the University of Washington, Seattle will unveil to the 18th USENIX Security Symposium in Montreal an e-communications system that destroys messages soon after they have been sent.

The formal description technology based on LOTOS, the formal transformation, the formal validation and implemenation are generalized. Constructions of communication service and communication protocol, transformation from service specification into protocol specification based on bisimulation equivalence are also stated in detail. Application of LOTOS specification styles and architecture concept in service and protocol design is studied as an emphasis.

The main characteristics of thenew generation of network computing are large-scale, decentralized control, dynamic,and autonomous. Since publish/subscribe systems have the advantages of loosecoupling, anonymity, many-to-many communication and scalability, they have becomeimportant infrastructure middleware platforms support for the new generation ofnetwork computing.
