The research of hardware encryption card based on chaos

摘要

In recent years, with the rapid development of computer information technology, a lot of information has been speeded with the internet. The information leaks often cause huge losses, so more and more attentions were paid to the research of information security. Hardware encryption card based on chaotic encryption algorithm is compared with traditional software encryption method, it has a speed computing, difficultly gain and easily be stolen, etc. Discussed in this article is based on the research of the DSP chaotic encryption card, its three aspects in detail including the study of chaotic algorithms, hardware design and software design.
