K-PAKE: post quantum password authentication key exchange protocol for satellite networks

연구 분야: Cryptography

학회: Cluster Computing

Satellite networks are crucial to our communication systems and significantly impact our daily lives. With the advent of quantum computing, traditional password-authenticated key exchange (PAKE) protocols, over classical cryptography challenges, face new security vulnerabilities in the post-quantum era. Addressing these vulnerabilities requires updating the authentication procedures of satellite communication systems to be quantum-resistant. This manuscript introduces a provably secure one-round PAKE protocol named K-PAKE, which utilizes Smooth Projective Hash Functions with Gray Zones (SPHFwGZ) and the post-quantum algorithm CRYSTALS-Kyber. K-PAKE is designed to withstand quantum attacks while reducing the number of communication rounds required. The manuscript thoroughly verifies the security of K-PAKE, adhering to an enhanced standard security model. Experimental results confirm that K-PAKE not only reduces communication frequency and computational demands but also strengthens security assumptions and real-world applicability.
