CERS Algorithm: An Enhanced Security System Using Hybrid Cryptosystem

Abstract

Communication and information exchange through the internet have a significant risk of information leakage owing to security issues. In this paper, a new hybrid cryptosystem design is proposed in order to accomplish high-security communication. The Schnorr authentication algorithm is used in this research to ensure a high degree of data security and authentication by integrating RSA, El Gamal, and Chaos-based cryptosystems. The process begins with El Gamal's key generation scheme. El Gamal is well-known for its ability to compute complex discrete logarithms, and when paired with RSA, its abilities are dependent on the difficult process of factorization of large prime integers. Multiple key schemes were generated using the chaotic system. Finally, the Schnorr was utilized to verify the original sender of the message.
