Migration In Position In The Workflow Management System Security

A workflow was a transaction model that can be implemented by a workflow system. It was built to realize the integration and automation of the management process under the support of advanced computers. Implementing automation of the process was the characteristic of the workflow. It was to make human and all kinds of application tools to cooperate, so that a specific transaction process was finished. The appearance of mobile agent provided the more choices for workflow system design. Mobile agent had many advantages in workflow system design, such as reducing the network flux, suit the mobile user, helpful to data integration and possess parallel feature, etc. One characteristic of the distributing operating system was that it needed frequent data and service transfers. The migrating workflow manage system combined this characteristic with the mobile agent and introduced mobile agent to the tradition workflow system. The migrating workflow manage system highly increased the agility of the workflow system to adapt the active environment.The migrating workflow gave a new direction within the workflow management area, at the same time, it brought new security risk to the migrating workflow management system. The migrating workflow both had the characteristics of workflow and mobile agent. Its security issues can not be considered in only one side. To build the appropriate migrating workflow security system, both the workflow security points and the mobile agent security problems must be calculated.Owing to the working characteristic of migrating instance, the security problems in migrating workflow management system contained the workplace security problems and the migrating instance security problems. This paper particularly studied the workplace security problems, gave workplace security policy. It managed the migrating instance's active space and time in the workplace to protect the workplace according to the security policy.Based on the workplace security policy, this paper offered a security model of workplace. It presented a security mechanism of the server and wok stations in the foundation of workplace structure, and researched the identity authentication, activity response and access control of the migrating instance.
