Encryption is one of the well known techniques to provide security in transmission of multimedia contents over the internet and wireless networks. The simplest way of encrypting multimedia content is to consider the three-dimensional image or video stream as a one dimensional stream and to encrypt the entire content using standard block ciphers like AES,(More)
In order to avoid the flaw while keeping all the merits of image encryption scheme based on line maps, an improved image encryption scheme is proposed, which extended the original 2D scheme to 3D. An image with size N×M is firstly depicted by a 3D bit matrix, and then it is supposed as composed of 8×M vectors with size N. Line maps are used to(More)
