The security of RC4 algorithm using keys generation depending on user's retina

Digital technologies grow more rapidly; information security threats are becoming increasingly dangerous. Advanced and various cyber-attacks threats, like targeted emails, exploitation, pose a critical threat that basically undermines our trust in the digital society. Rivest cipher 4 (RC4) algorithm is significant of stream could be utilized with protocols internet, advantage RC4 it simple effective. There several weak, especially after pseudo-random generation (PRGA), PRGA's initially 256 rounds (the amount permutation). Several modified studies have been published thus far, however, they all face either standard privacy or achievement evaluation issues. This paper proposes new based on user's retina (RC4-Retina), which has solved both these weak points was indicated algorithm. The novelty key scheduling (RKSA), generated by relying will modify matrix permutation used to configure keys. efficiency improved measured depending average ciphertext different keys messages, results were good compared
