The Research Of Remote Dynamic Reconfigurable Encryption And Decryption Based On ARM9and FPGA

With the increasingly wide range of applications FPGA chip scale is increasing rapidly. Research in the field of encryption and decryption remote dynamic reconfiguration of FPGA-based technology can be extended reconfigurable FPGA technology and the range of applications. Whether the current work, learning, life dependent on the network increasing, despite the high level of Internet technology and electronic technology, but the vulnerability of network information is not small, how to safely use high technology to living and working with how convenient to solve information security problems currently facing.Based FPGA dynamic reconfiguration technology to research the control by ARM to achieve the FPGA dynamic reconfiguration, when the system needs to transmit information to the control terminal, the system can self-encrypting files and sent back to the terminal, the terminal receives the decryption decryption module and uploaded to a computer for processing operations, so you can achieve semi-automated remote system. Meanwhile, the combination of FPGA flexibility to change the application system functions and hardware encryption for data on their own strengths, choose the interface with mini-PCIe3G wireless network card for wireless transmission of data, enabling remote control and remote receiving and sending end encryption and decryption of data, ensure data transmission security.Research of the system so that each application can ARM FPGA decryption module to control the formation, thereby increasing the efficiency of encryption and decryption, and better safety protection system to prevent others from tampering with the application module function.
