Study on Image Encryption Algorithm Based on Chaotic Theory

With the rapid development of high-tech such as the cloud technology, information security has become more critical than before, so the cryptography assunes a key technology in information security. Recently, some new cryptography theories have attracted increasing attention under the background of research on algorithm efficiency and security has become the current hot research topic. Chaotic algorithm is very suitable for stream cipher encryption not only for its sensitivity to initial conditions for time series generated but also for its complex structure which is difficult to analyze and forecast. At the same time, it can provide smart pseudo random sequence with excellent randomness, correlation and complexity. This paper mainly studies about the image encryption algorithm based on chaotic theory.
