面向迁移工作流管理系统中工作位置的安全问题研究

迁移工作流为工作流技术提供了一个新的研究方向，同时也给迁移工作流管理系统带来了更多的安全问题。文中重点研究迁移工作流管理系统中工作位置的安全问题，根据这些问题给出了工作位置的安全策略，并根据安全策略提出了一个工作位置的安全模型，并详细介绍了模型中的安全加载、状态监测和访问控制几个方面的关键技术和实现。

Study of workplace security in the migrating workflow management system

The migrating workflow gave a new direction within the workflow management area, at the same time, it brought more security risks to the migrating workflow management system. 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. In this paper, the workplace security problems were studied particularly, workplace security policy was given, and a security model of workplace was offered. Some key techniques and its implementation about the security model such as security loading, state monitoring and access control were also discussed here.
