Grid Multi-Agent Authentication Proxy and Its Application in Teaching Resources Share

With the development of grid technology,independent education enterprise with similar goals,forming loosely coupled virtual environment for collaboration and resource sharing.The construction of virtual teaching environment is hampered because of the security,however.In this paper,proposed multi-degree proxy authentication strategy to achieve identity proxy authentication of resource request,which is to share all teaching resource of virtual teaching environment after user's single-sign-on.The research result shows that this method can resolve many security problems such as reliability,authenticity,anonymity, re-send,and non-repudiation.
