Feistel inspired novel hybrid cryptosystem for information secure processing

Year: 2025

Type: article

Abstract: In this paper, we propose a novel hybrid encryption algorithm that enhances security by integrating DNA encoding, the Rabin algorithm, a one-time pad (OTP), and a Feistel-inspired structure. The algorithm begins with the application of a DNA-based OTP key, used exclusively for a single secure communication session. In the second step, it combines public and private keys to generate a Rabin key. By incorporating a Feistel-inspired scheme and leveraging the inherent randomness of DNA sequences, the resulting ciphertext achieves a high level of security, making it significantly more challenging to decrypt without the private key.
