Abstract: In this paper, we propose selective bitplane encryption to provide secure image transmission in low power mobile environment. We assume a 512 X 512 pixels image to be given in 8bit/pixel (bpp) precision. We consider the 8bpp data in the form of 8 bit planes, each bit plane associated with a position in the binary representation of the pixels. The Selective or partial encryption (SE) approach is to AES encrypt a subset of the bit planes only, starting with the bitplane containing the most significant bit (MSB) of the pixel. Each possible subset of bit planes may be chosen for SE the minimal percentage of data to be encrypted is 12.5 % increasing in steps of 12.5 % for each additional bitplane encrypted.
