Network Of Collaborative Work Systems Security Architecture And Security Of Information Transmission

In order to win the global market, manufacturing organisations must search for new approches to shorten the time to market and enhance the qulity of their products. The great progress of web technology in the past few years has brought manufacturing organisations new chances to realize it. Some new techonology based on web has been proposed, including web-based cooperative work system (WCWS). WCWS is the product of integration of web and cooperative work system and because of its attractive features it is studied by many researchers now. Information security is one enabling technology of WCWS and communication security is an important part of information security.In order to realize the communication security in WCWS, some techonologies related to communication security in WCWS, including cryptology, key management and security protocol, are studied in this paper. In order to illustrate the relationship among the WCWS scheme, the information security scheme and these techonologies, architecture of WCWS is proposed firstly and then architecture of information security of WCWS is presented. Finally, the techonology to implement information transmission security is described and an instance is given out.
