Abstract: Based on ID-based cryptography system, a new registration protocol was proposed. With the random numbers produced by entities, the session keys can be calculated, avoiding transmitting the session keys on the wireless link and realizing the distribution of the session keys among MN, FA and HA safely. Public key algorithm is employed to authenticate the entities, and at the same time by comparing the random numbers which are received and dispatched by the entities, the entities can be authenticated again. The analysis of the protocol indicates that it can satisfy the conditions of the secure correspondence.
