Abstract: | Quorum system is a preferable model to construct distributed access control architecture, but not all quorum system can satisfy
the requirements of distributed access control architecture. Aiming at the dependable problem of authorization server in distributed
system and combining the requirements of access control, a set of criterions to select and evaluate quorum system is presented.
The scheme and algorithm of constructing an authorization server system based on Paths quorum system are designed, and the
integrated system performance under some servers attacked is fully analyzed. Role-based access control on the Web implemented
by this scheme is introduced. Analysis shows that with certain node failure probability, the scheme not only has high dependability
but also can satisfy the special requirements of distributed access control such as real-time, parallelism, and consistency
of security policy. |
