Security system evaluation and IP encryption method of 6G satellite internet

The invention discloses a 6G satellite internet security system evaluation and IP encryption method, which aims at a link IPSec system transmitted by a satellite network, analyzes the computing power fluctuation condition in the encryption and decryption process of an IP message transmitted by a link, and tracks possible abnormities; meanwhile, virtual mapping is carried out on encryption and decryption nodes of the SatIPSec of the link layer in the IP message secure transmission process, and a temporary virtual autonomous network is formed; satellite internet space-based security protection is realized based on IP message integrity verification; and classifying data generated by each layer in the security system of the satellite internet and a logical relationship result, and then calculating in combination with an evaluation index, so that the protection capability of six layers of the security system of the satellite internet is proofread. According to the invention, abnormity tracking and IP encryption op
