摘要：Cloud computing can improve utilization of powerful computer systems. However, security problems become an important challenge in the cloud systems. Implementation of antivirus software can cost a lot of resource. This paper advanced an access-control based architecture of operation systems which ensure the high availability of the whole system. System resource cost on security can be dropped by the implementation of this architecture.
