communication and recovery issues in grid environment
Computational grids provide significant computing power by sharing resources across administrative domains. But only in secure environment can the performance of girds arrives at maximization. Once a grid node or communication between nodes is breakdown, computing power will descend quickly. So in this paper we propose a distributed secure structure which emphasis security issues of the whole grid system by monitoring communication of hosts. The security system provides the basic functions of access control mechanism, and cares about the ability of host cooperative communication. For enhancing system reliability, we also discuss the fault tolerance and recovery mechanism.
