Abstract: An access control scheme for synchro-coroutine, an algorithm to calculating public authorities and an automatic coding method are proposed to resolve the problems resulted from information sharing using synchro-coroutine among cooperant members, including illegitimate access, efficiency problem and the problem of how to control dynamic created information. The application result shows that the access control scheme can reduce the communications traffic to 50 percent and the algorithm is feasible.

Key words: synchro-coroutine, access control, public authorities
