Embedded Systems Based On Chaos Encryption

Chaos is a kind of complicated and random phenomenon that is determined wholy bydeterministic nonlinear systems. It is inner randomicity. Now chaos is discovered in many scientific fields s. And chaos theory and application research are widely paid attention to and became a hotspot in international academy. So the secure communication systems that apply the chaotic signal have strong anti-decryption and long unpredictability. The embedded system has got rapid development these yeas and applied widely to many fields such as manufacturing, communication, automobile, aircraft, military and so on. So apply the chaos encryption to the embedded systems has great foreground.This dissertation reviews the history and status of embedded system and the research of chaos in chapter 1, and presents the concept, the basic analytical methods of chaos in chapter 2. Then two subjects on chaos are focused on in particular, including chaos modulation techniques and synchronization, secure communication system based on chaos mapping.In chapter 3 and chapter 4, the embedded operation system μc/os-Ⅱ and ARM kernel was introduced. Including the kernel analy of μc/os-Ⅱ and the main characteristic of ARM, and the transplant of μc/os-Ⅱ to ARM.In the final chapter This dissertation present the embedded system and the new way of encryption with chaos. With only a few amending, it can work in reality.
