Multi-party key exchange scheme based on supertropical semiring

In an era where digital communication and data sharing are everywhere, ensuring the security of sensitive information is important. Cryptographic protocols are essential for establishing secure communication over potentially insecure networks. This paper introduces a novel three-party key exchange protocol based on a newly constructed supertropical semiring. By leveraging the unique algebraic properties of supertropical semirings, our protocol aims to provide enhanced security against known attacks on tropical based cryptographic schemes. We demonstrate the security and efficiency of our protocol through detailed analysis and examples, showing its robustness in protecting confidential information.
