Popis:	Today the transmission of multimedia data including image and video is growing in telecommunications. Security is one of the main issues in transferring such sensitive informat ion. Powerful image encryption algorithm is the sol ution for this problem. This paper is an implementation of a color image encrypt ion algorithm based on Rubik’s cube technique. The Rubik’s cube technique is used for pixel permutation and a bit substitutio n method based on DNA sequences are used to change the value of each pixel on the image. Then the time-stamp is appended with enc rypted image, which can be used to identify the rep lay attack. For evaluating the performance of the algorithm a series of tests are performed. These tests include information entr opy analysis, correlation analysis, analysis of NPCR and UACI values etc.
