Novel image encryption algorithm based on wave transmission
Qing Zhou · Journal of Computer Applications · 2009
A novel image encryption algorithm was proposed. Through simulating waves' transmission, the gray-level value of the pixels in the image was changed by adding the corresponding displacement of the wave to the original gray-level value according to the distance between the pixel and the source point, then modulo 256. When encrypting an image, several waves could be performed to enhance our algorithm as a phenomenon called superposition of waves. Integrated with self-adaptive encryption, this algorithm is easy to realize and computationally simple while achieving high security, high speed, high sensitivity and other properties simultaneously. Simulation results on a typical gray-level image demonstrate the high performance.
