Emphasis has been given to the architecture and interaction. Based on the C/S(Client/Server) architecture we manage the personal informations on the server and maintain all the workstations through TCP/IP protocol. All the queries are done through ODBC. For the cooperation of workstations we select MDI as the basis of our interface and apply OLE technique in it. Furthermore we apply multithread to manage the shared resource and individual resource. Our applications results show that C/S architecture can be an excellent platform for MIS developing and the principles for human-machine interface perform well in this kind of applications.展开更多

On the putpose to build the secure group communication among of a group of client users and one server, in this paper, we will present a new password-based group key agreement protocol. Our protocol will meet simplicity, efficiency, and many desired security properties.展开更多

The availability and maintenance cost functions are obtained by means of establishing the application server aging model and the boundary condition of the optimal rejuvenation time is analyzed. Theory analysis indicates that the two-level rejuvenation strategy is superior to the traditional single level one. Finally, evaluation experiments are carried out and numerical result shows that compared with the traditional rejuvenation policy, the rejuvenation strategy proposed in this paper can further increase availability of the application server and reduce maintenance cost.展开更多

Meanwhile, Redundant Array of Inexpensive Disks (RAID) storage system are presented and the centralized FCP/SAN huge storage technology is introduced in terms of its scalability, throughput, and connectivity performances.展开更多
