METHOD FOR SHARING AUTHENTICATION KEY BETWEEN TERMINAL AND MAINTENANCE SERVER AND METHOD FOR TERMINAL REMOTE MAINTENANCE IMPLEMENTATION

摘要

PROBLEM TO BE SOLVED: To provide a terminal-maintenance server authentication key sharing method and a terminal remote maintenance implementing method which can remotely maintain a terminal by IPsec with high security without any operator's operation on the terminal side. SOLUTION: After a terminal 1 is authenticated accompanying specific sharing authentication information as a fault of the terminal 1 is detected, a fault code and the global IP address of the terminal 1 are sent to the maintenance server 3, the setting of an authentication key of IPsec and the initiator setting of IPsec are written to a VPN gateway 4 controlled with commands from the maintenance server 3, and then necessary remote maintenance is carried out for a server part 11 and a router part 12 of the terminal 1 through a VPN tunnel set between the terminal 1 and maintenance server 3 (VPN gateway 4).
