Research on Association Securities in Cross-domain Interoperation Model in Pervasive Computing

Cooperation and sharing of resources are needed urgently between domains in pervasive computing environment, so building an effective cross-domain authorization model become a key issue. The IRBAC 2000 model accomplish flexibly interoperation by dynamic inter-domain role mapping, but how to manage the associations is not discussed, which may cause security problems. Algorithms to detect these security issues are proposed, and the experimental results show that our algorithms can improve the security of the model, so the algorithms can be applied as a security checking mechanism during role mapping in pervasive computing environments.
