Quantum polarized image encryption — A secure communication

This paper proposes an encryption scheme, where bit-XOR operation between the rows of quantum polarization angles 0°, 45°, 90°, 135° and a key generated by quantum polarization angles is done. Then the bit-XORed rows are swapped from 0°to 45°and 90° to 135°. Then the image is divided into four blocks and bit-XOR operation is performed between each tile and a key generated using quantum polarization angles. Then the tiles are concatenated to form an image. The resultant image is encrypted by random permutation and bit-XOR operation is performed with randomly generated key to form the final encrypted image.
