A New Visual Public-Key Cryptosystem Based On Non-Expansion Technique And Boolean Operations

Many public-key cryptosystems are used in our daily lives to attain privacy, authenticity, integrity and non-repudiation. However, most of the existing public-key algorithms are based on complex mathematical computations. Until recently, building a highly secured public-key cryptosystem without util...
