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.

Embodiment Construction

[0043] In this example, the system hardware platform adopts the Spartan3E development board of XILINX Company as the encryption and decryption chip board, and uses the Microblaze soft core with the hardware DSP coprocessor designed by Verilog HDL; the software platform is ISE and EDK software of XILINX Company; the video acquisition uses a digital camera Cooperate with video acquisition card; video data transmission and reception is based on Ethernet, using LwIP embedded TCP / IP network communication protocol; after encryption, data transmission between boards uses ZigBee technology for wireless transmission; video data encryption and decryption algorithm is chaotic pseudo-random sequence coding (CPRS); The implementation of the algorithm is based on hardware co-processing designed with FPGA. These technologies can meet the requirements of high security intensity.

[0044] The present invention will be further described below in conjunction with the accompanying drawings and sp...

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 moduleafter 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 fields; [0001] The invention relates to the technical field of secure communication, more specifically, to a network video monitoring system based on FPGA to realize chaotic encryption. 2. Background technology [0002] Since entering the 21st century, information and network technology have been widely used, and network information communication has entered people's production and life irresistibly. The rapid development of information technology has brought many new problems and challenges while improving productivity and bringing convenience to people. Information security has become one of the prominent hot issues. According to the survey organized by the Federation of American Scientists and experts' estimates, the economic loss caused by information security issues in the United States is as high as 15 billion U.S. dollars every year. A large amount of data is transmitted through the open network in the form of plain text, which has serious security risks...
