摘要
校园网账号管理系统缺乏时间约束,造成用户账号在某些时间段上易被攻击和盗用。提出了一个基于TRBAC模型的校园网账号管理系统的设计方案:构建一个访问控制系统的总体结构,结合DBMS系统设计了系统表。该方案通过时间约束可以避免用户账号易被攻击和盗用,可以有效地解决校园网安全访问控制问题。
The account management system of campus network has not temporal constraints, its account numbers are easily attacked and embezzled during some periods. A project on the account management system of campus network based on TRBAC is developed： Firstly a frame of access control is constructed to describe the TRBAC system operated in DBMS; secondly the system role table is designed by combining with DBMS system. The network attacks and embezzlements are avoided and the problems of campus network security is solved by temporal constraints.
