The invention provides an inter-satellite networking identity authentication method for low-orbit broadband satellites, which comprises three parts, namely a system initialization stage, an inter-satellite networking authentication stage and a session key negotiation stage, in the system initialization stage, the low-orbit broadband satellites interact with a ground key management center to complete registration of identity information; parameters such as a public key matrix, a satellite identity label and an ID certificate are preset in the low-orbit broadband satellites, and in the inter-satellite networking authentication stage, identity authentication is carried out between the low-orbit broadband satellites of adjacent orbits, and in the session key negotiation stage, key negotiation is carried out by using the parameters generated in the authentication process.

The application discloses a kind of lightweight multi-user multi-factor two-way authentication registration method, belong to network security technical field.It includes: each user equipment collects biological characteristics, generates biological characteristic key and public parameter;Each user equipment initiates registration to authentication gateway, and carries out the registration between user equipment;User equipment carries out the transmission of hash operation message authentication code between, realizes the verification between users;First user equipment selects a random number, calculates the value for verification, and sends to authentication gateway;Authentication gateway solves out random number, carries out preliminary verification to each user equipment;Select one of challenge response pair from the registered data, calculate the value for verification, and send to the nth user equipment;User equipment n calculates the value for verification, and sends to authentication gateway;Authentication gateway calculates verification value, completes two-way verification.The application realizes that user equipment is authenticated to authentication gateway two-way, and enhances the security of user authentication.
