Abstract: In this article we present a new approach using Vigenere and metaheuristics to resolve a problem of pixel shuffling to cipher an image. First the image is adapted to match the resolution system by transforming it to a list of intensities and coordinates. The idea is to use Vigenere encryption to maximize the confusion by widening the domain of intensities. Then, metaheuristics play the major role of encryption, generating an appropriate Meta key in order to shuffle the lists. Thus, both Vigenere key and Meta-key are used for encryption and later in decryption by the recipient. Finally, a comparison of different metaheuristics is proposed to find the most suitable one for this cryptosystemt.
