Scytale -- An Evolutionary Cryptosystem
This addresses the problem of developing quantum-resistant cryptosystems for secure data transmission, though it appears incremental as it builds on existing cellular automata concepts.
The paper tackles the need for new encryption schemes resistant to quantum computing by proposing a block encryption algorithm based on Reversible Cellular Automata, specifically using Critter's Rule in a Margolus Neighborhood, and demonstrates its performance against various attacks with benchmark results.
With the advent of quantum computing, and other advancements in computation and processing capabilities of modern systems, there arises a need to develop new trapdoor functions that will serve as the foundation for a new generation of encryption schemes. This paper explores the possibility of one such potential trapdoor function using concepts stemming from Reversible Cellular Automata (RCA) -- specifically, the Critter's Rule set up in a Margolus Neighborhood. The proposed block encryption algorithm discusses how sensitive data can be manipulated and converted efficiently into a two dimensional sequence of bits, that can be iteratively evolved using the rules of the RCA and a private key to achieve a desirable level of encryption within a reasonable runtime. The performance benchmark and analysis results exemplify how well the proposed encryption algorithm stands against different forms of attacks.
