Design method of an efficient multi-mode authentication protocol scheme for satellite communication

Abstract： Aiming at the problems of high authentication delay in the existing satellite-ground cooperative authentication mode, and the ground authentication server is vulnerable to failure when attacked, this scheme innovatively proposes a switchable and efficient multi-mode authentication scheme. The scheme adopts the authentication mode of primary use on the satellite and standby on the ground. Under the authentication mode on the satellite, it can effectively reduce the high communication delay caused by the traditional satellite-ground authentication transmission process, and achieve fast authentication without relying on the ground attribution network. When the on-satellite authentication mode is not available, the ground authentication mode can be switched quickly to ensure the stability and reliability of the authentication process and improve the system stability and survivability. At the same time, the scheme uses hash algorithm and symmetric encryption algorithm to complete the authentication core operation, effectively reducing the calculation cost of the authentication process, and has high application value in improving the access efficiency and security of satellite communication equipment.
