S-Shark安全工作流管理系统设计与实现*

Considering the poor security mechanism in workflow management system,and with the method of improving workflow information model,this paper presented a security workflow access control model.Based on the traditional model T-RBAC,the new model resolved the separation of duty constraint and cardinality constraint.Finally the paper implemented a secure workflow management system S-Shark(secure-Shark).S-Shark system was designed based on Java open source project Shark system,in which ETRBAC model's secure mech...
