Keyless Cryptosystem Based on Latin Square for Blockchain and Covert Communications

Abstract

The recent advances in cryptanalysis techniques and the leakage of information about the cryptosystem used are major threats to information systems. An adversary may succeed in decrypting ciphertexts, while users of a particular cryptosystem unknowingly continue to use the compromised cryptosystem. In this paper, we present a novel cryptosystem based on Latin Square for Blockchain and Covert Communications. This cryptosystem is capable of operating in quadruple modes keyless, symmetric, asymmetric, and hybrid encryption to Cipher In Cipher, and hence we call it CipherInCipher. Unlike all contemporary techniques including obscurity, CipherInCipher is a public-based approach that does not depend on the secrecy of any of its related components. It attains a high level of security that protects private information not only by having strong ciphertext but also by preventing an adversary from obtaining the actual ciphertext too. We analyze the cryptosystem proposed and present a validation study that demonstrates the robust capabilities of achieving the cryptographic goal.
