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 ...

However, existing signcryption schemes remain vulnerable due to their reliance on a single certification authority (CA) managing all keys. The cryptography fundamental logics (CFL) authentication ...

Recently, Libert and Quisquater proposed an efficient signcryption scheme based on the hardness of q-Diffie-Hellman problems in Gap Diffie-Hellman groups. Their scheme is quite efficient: the ...
