Stream Cipher Based on Pseudo-Random Number Generation Using Optical Affine Transformation

Abstract

We propose a new stream cipher technique for 2-D image data which can be implemented by iterative optical transformation. The stream cipher uses a pseudo-random number generator (PRNG) to generate pseudo-random bit sequence. The proposed method for the PRNG is composed of iterative operation of 2-D affine transformation achieved by optical components and modulo-n addition of the transformed images. The method is expected to be executed efficiently by optical parallel processing. We verify performance of the proposed method in terms of security strength and clarify problems on optical implementation by the optical fractal synthesizer.
