Multi-domain authentication model based on lattice in grid environment

Basing on the analysis of the existing echnologies of multi-domain authentication and the use of lattice in building a new grid network, a new identity-based model and the corresponding certification of multi-domain authentication were proposed. The model bases on the construction of a grid network with the feature of lattice and uses the identity-based authentication system, and avoids the network bottleneck problem and the complexity of routing in finding the authentication paths brought by using traditional PKI framework. The optimization of the selection of authentication path in grid environment and the anonymity of entity authentication are also simultaneously solved.
