Abstract
In this paper, a new algorithm for image encryption using the scan method is proposed. Using SCAN language, it is possible to generate a wide range of scanning paths based on the spatial accessing methodology. The proposed algorithm is implemented using different gray and color images, and the experimental results and security analysis indicate the advantages of the proposed algorithm. The original image can be reproduced using this algorithm without any loss of information. The algorithm is simple and fast as compared with other recent approaches. It is secure enough to be used in a wide range of applications, as it has passed all the security requirements. This paper presents an overview of the encryption and decryption process using the proposed algorithm. The implementation of the algorithm is done in MATLAB and tested on various gray and color images.
