Abstract

The application provides a trusted time stamp service system, a method, equipment and a storage medium based on satellite communication, which are used for receiving time service time of satellite signals through a satellite NTP server, starting NTP service and providing network time service; the terminal trusted time stamp server is used for providing the endorsement service of the trusted time stamp for at least one terminal device in the same local area network and generating the trusted time stamp credential through a trusted time stamp interface. The stability and service efficiency of the trusted timestamp service system can be improved based on satellite communication. The method solves the problem that when the trusted time stamp service center provides service for external programs or operators through the Internet, the trusted time stamp service cannot be obtained in places without Internet access or in places with poor network environment.
