Image Encryption and Decryption System with Clock Controlled Destruction

Image encryption is an important tool for encrypted communication. Pixel dots can carry a lot of information and are more confusing than text encryption, which cannot be recognized with the naked eye and cannot be easily analyzed for encryption laws, so it has an important position in modern encryption technology. We have improved the traditional image encryption technology by using symmetric and asymmetric encryption techniques and adding the clock parameter as a factor to participate in the synthesis to achieve the automatic destruction function. This algorithm has a much higher encryption and decryption speed than conventional encryption algorithms due to the operation at the array level and the use of xor encryption on bit operations. After an experiment of encryption and decryption of images, we proved that this method has a promising application for commercial and military encrypted communications.
