Design And Analysis Of A Chaotic Rossler-Based Cryptographic Scheme For Secure Cellular Communication
Year: 2025
Type: article
Abstract: Ensuring secure communication in cellular networks is a critical challenge due to their vulnerability to eavesdropping and unauthorized access. This paper proposes a novel cryptographic framework that integrates the chaotic Rossler system with the KASUMI block cipher to achieve enhanced security in mobile communications. The Rossler system is employed as a random number generator to produce high-entropy sequences, which are then utilized to construct dynamic substitution boxes (S-boxes) for encryption. The proposed system encodes 64-bit plaintext using 128-bit keys and achieves improved security metrics, including randomness, balanced output, Hamming distance, and avalanche effect. Experimental validation using the NIST statistical test suite confirms the randomness of the generated sequences. Comparative analysis with existing Lorenz-based cryptosystems highlights the improved avalanche effect and competitive performance of the proposed approach, establishing it as a viable solution for secure cellular communication.
