Design and implement of a Logistic chaotic encryption and pseudo decryption algorithm based on FPGA

Coming of the Popular Science indicates the rapid development of information communication. It has brought great changes to our lives, but the subsequent problems of information security are bothering us. Looking for an efficient and safe way to protect the information security has become an important problem that needs to be solved urgently. In recent years, data encryption system based on chaotic sequence has been widely used and displayed advantages. This paper introduces an improved algorithm of Logistic chaotic encryption with unique input mode and a pseudo decryption algorithm. Information encryption and decryption based on FPGA are designed and implemented. The results show that this method is safe and reliable. It can meet the requirements of confidential communication.
