Network Of Collaborative Work Systems Certification System And Certified Technicians

With the development of information technology and the rapid spread of Internet, network manufacturing is the necessary trend of manufacturing. Thus the research on web-based cooperative work system (WCWS) has great value both in theory and practice. Information security is one enabler of WCWS and authentication technology is an important part of information security. The purpose of this paper is to discuss the authentication technology in WCWS.Authentication is the first problem to be resolved in WCWS. In order to illustrate the relationship of all security models among WCWS, a WCWS scheme and an information security scheme are proposed in this paper. Some basic authentication technologies in WCWS are studied firstly and then a new authentication scheme of WCWS is presented and the security of some technology in which are analyzed in detail.Based on all above studies, the technology to implement secure authentication is described and a sample about user authentication in WCWS is designed, which prove out the feasibility of authentication scheme in this paper.
