网格代理认证技术在制造资源共享中的应用

制造技术的发展．使得各制造单位之间为了共同的需要形成一种松散耦合形式的虚拟企业来共享制造资源，牵制共享的一个主要问题是：虚拟企业的成员都希望能像使用自己的资源一样使用其他成员的资源．而各成员又不会希望改变自己的资源使用策略或交出自己的资源控制权去迎合其他成员的使用。通过对当前计算机网格安全技术的研究，使用用户代理机制，在数字制造系统中部署数字制造资源多级代理授权认证策略，实现各虚拟企业之间资源请求的身份代理认证，用户单点登录即可共享虚拟企业的所有数字制造资源。

Grid User Authentication Proxy and Its Application in Manufacturing Resources Share

With the development of manufacture technology,independent enterprise with similar goals are forming loosely coupled virtual enterprises for collaboration and resource sharing.The construction of virtual enterprises is hampered,however,by two conflicting goals:all members of the enterprise should have access to a resource as if it was their own,but participating institutions must not be required to change local security mechanisms or surrender control over their access control policies.Researching on current computer grid security technology,using user proxy mechanism,assigning digital manufacture resource multi-degree proxy authentication strategy in digital manufacture system to achieve identity proxy authentication of resource request between each virtual enterprise,which is to share all digital manufacture resources of virtual enterprise after user's single-sign-on.
