Ship-shore identity recognition method and system based on domestic password

The invention provides a ship-shore identity recognition method and system based on a domestic password. The method comprises the steps that ship-end equipment submits a login request to a shore-end gateway; mutual authentication and key verification are carried out on the ship-end device, the shore-end gateway and the shore-end wireless device, identity recognition is carried out on the ship-end device, a session key used for communication between the ship-end device and the shore-end wireless device is negotiated, and identity recognition is completed. According to the method, key parameters in the authentication process are subjected to encryption operation by introducing a series of national secret algorithms, so that the safety of the whole authentication process is improved, and meanwhile, the operation pressure on shore-end wireless equipment is also reduced. Through the identity authentication method, off-line password guessing attack, session key leakage attack and man-in-the-middle attack can be eff
