Network video monitoring system based on FPGA chaotic encryption

Abstract

The invention relates to a network video monitoring system based on FPGA chaotic encryption, comprising a server terminal, a client terminal and a system configuration terminal. The server terminal comprises a plurality of cameras, a video server, an encryption module and a signal sending module; the client terminal comprises a signal receiving module, a decryption module and a client terminal player; video frequency collected by the plurality of cameras is coded by the server, then input into the encryption module via the Ethernet and sent to the client terminal via the signal sending module after encrypted; the signal receiving module of the client terminal receives the encrypted video data and then sends the data to the decryption module for processing and finally the client terminal player plays the video data; the encryption module and the decryption module are respectively an FPGA encryption board and a decryption board; the encryption process and the decryption process of the encryption module to video flow are as follows: the encryption module adopts a CPRS array which is cut and operates with a plain text data module 2, and then sent; and the receiving terminal of the decryption module obtains the same CPRS array, and then operates with a cryptograph module to realize decryption.

Description

1. Technical field; [0001] The present invention relates to the technical field of secure communication, and more specifically, to a network video monitoring system that implements chaotic encryption based on FPGA. 2. Background technology [0002] Since the beginning of the 21st century, information and network technologies have been widely used, and network information and communications have entered people’s production and life unstoppable. The rapid development of information technology has not only increased productivity and brought convenience to people, but also brought many new problems and challenges. Information security has become a prominent hot issue. According to surveys organized by the Federation of American Scientists and estimates by experts, the United States causes as much as 15 billion U.S. dollars in economic losses each year due to information security issues. A large amount of data is transmitted through an open network in the form of plain text, which has...

AI Technical Summary

Problems solved by technology

However, the existing video surveillance systems generally use plaintext data transmission, which has made outstanding contributions to social security, but also brought new security issues, such as unauthorized access to data, threats to data integrity, and violation of user privacy, etc.

Moreover, due to the particularity of the network monitoring system as a security barrier, its own security problems have brought great security risks to the society.
