Cross-Domain Authentication Model Based on Lattice

Aiming at the problems and the shortcomings of the existing authentication model, a lattice based cross-domain model is proposed. At first, by the use of the lattice theory, and on the two dimensional coordinates; this model builds the credit-domain alliance and the user alliance. It imports the interplay double validates mechanism, so it can avoid the abuse of centralized plans for the whole authentication. Secondly, it uses the superiority thought of the existing authentication system to strengthen the integrity of the model. Then, a freely open cross-domain authentication platform and Single-Sign-On Mechanism is established. After the certification and analysis, this model proved to have a good Practical character and an extremely large extension space.
