Signcryption based on Elliptic Curve CL-PKC for Low Earth Orbit Satellite Security Networking

Low earth orbit satellite communication has lower latency and is more suitable for real time communication than high orbit and medium orbit satellites, secure networking is crucial for providing continuous services to low earth orbit satellites. This paper proposes a method for dynamic secure networking of low earth orbit satellites, the method is based on signcryption elliptic curve algorithm in ISO/IEC 29150:2011. The biggest contribution is the combination of certificateless public key mechanism and signcryption algorithm to support secure networking of satellites. Finally, Scyther was used to conduct security analysis on the algorithm and process, it has been proven that the certificateless public key signcryption system can effectively solve the problems of authentication and secure transmission between satellites.
