Design of Satellite Internet Defense System Based on Mobile Target Defense
While satellite Internet promote information inter connectivity,they also raise increasingly complex security issues.This ar-ticle introduced mobile target defense as proactive defense measure into the cyber protection of satellite Internet.By changing the IP ad-dress,protocol port information of satellite Internet pseudo-randomly,the system's resistance to interception attacks and denial of ser-vice attacks was enhanced,thereby achieving active defense.On this basis,a prototype system of satellite Internet based on mobile tar-get defense was designed,which solved some key problems such as synchronization scheme,hopping data transmission,and verified the feasibility and effectiveness of the prototype system.
