Implementation of modified GSO based magic cube keys generation in cryptography

Over the last few decades, tremendous and exponential expansion in digital contents together with their applications has emerged. The Internet represents essential leading factor for this expansion, which provides low-cost communication tools worldwide. However, main drawback of is related to security problems. In order provide secure communication, enormous efforts have been spent cryptographic field. Recently, algorithms become increasing information safety. these require random keys can be regarded as compromised when are cracked via attackers. Therefore, it substantial that generation should hard crack. paper, guaranteed one most efficient nature-inspired emerged by inspiring movements stars, galaxies, galaxy superclusters cosmos utilized a mathematical model (magic cube) generating hardly cracking number keys. proposed system, Modified Galactic Swarm Optimization (GSO) algorithm every row column magic cube faces randomly rotated until reaching optimal face, elements selected key from face. generated optimized used several versions RC6 encrypt various secret texts. Furthermore, also encrypting images using logical XOR operation. obtained results NIST tests proved uncorrelated. Moreover, system was
