FHE Cryptographic Systems with Using Chaotic Secret Key Generation

Abstract

Security is a fundamental characteristic sought by researchers and sought by users above all else. Any system balances efficiency with application and information security as one of its most important prerequisites. No matter how efficient a service system is and the features it provides, security is paramount. Cryptographic systems achieve the highest level of security. Among the modern encryption methods that help raise the level of security and credibility and increase user confidence are homomorphic encryption schemes, which help complete tasks and conduct operations in an encrypted form. These systems operate by generating secret keys, which underlie the system's strength. This research discusses the integration of chaotic systems with fully homomorphic encryption systems to produce strong secret keys it is called DUff-skg. The idea uses a chaotic duffing scheme to provide high-quality randomness for FHE keys, combining key unpredictability with mathematical security. The results confirm the effectiveness of the DUff-skg proposed key in homomorphic encryption systems.
