The Research on Authentication Protocol in the Environment of Manufacturing Grid

In order to improve the security and performance of authentication protocol in manufacturing grid, identity-based authentication protocol under standard model is constructed. Combining with the environment of manufacturing grid, this protocol can work under escrow and non-escrow models and different trust domains model. By introducing pseudo random function set, new authentication protocol realizes explicit double authentication under standard model. Compared to identity-based authentication protocol under other standard models, this protocol has lower computation complexity, so it is fit for application in resources-constrained environment of manufacturing grid. At last, based on hypothesis of difficulty, the safety of new authentication protocol is proved under standard model.
