A Secure Hybrid Symmetric Cryptosystem Combining Huffman Coding, Affine Transformation, and Cartesian Graphs

Abstract

We present in this research a new data symmetric cryptography model that combines three techniques: Huffman coding for compression, affine transformation for value obfuscation, and the Cartesian product of graphs to create a complex encrypted graph. The suggested model demonstrates enhanced cryptographic strength and adaptability across various document types. It also provides a high level of security due to to owing to the structural complexity of the generated graph and the multi-layered encryption method.
