3D extension of Baker map and its application to multimedia information encryption
Wang Zhi-quan · Kongzhi yu juece · 2004
Baker map is proposed to 3D space and an Baker map based encryption scheme is proposed. Compared to 2D Baker map, the extended 3D Baker map has much larger key space, much faster mixing speed and much wider applications such as the encryption of images, videos or multi-spectral image sequences. The encryption scheme combining the extended Baker map with spreading functions is of high security. And experiments show that the (algorithm )is much faster than DES, which makes it more suitable for multimedia encryption.
