Abstract: Collaborative commerce and design environment (CCDE) is characterized by of its numerous users, massive resources and dynamic change. In order to solve security problems coming from multi-domain, heterogeneity and dynamics, the security policies for CCDE were introduced. The security architecture for CCDE was constructed, which employed user proxy and resource proxy to provide resource & security access control. On the premise that the access control mechanism of each individual security domain was not changed in CCDE, secure resource access could be accomplished in cross-heterogeneous domains. The security of collaborative commerce and design activities were guaranteed and at the same time easy use of resource access was provided. At last, the framework of key supporting technologies of CCDE was also introduced.
