In this article, a technical solution to capture the data packet of the PCI-Express protocol using FPGA technology will be presented. Using the standard library of PCI-Express on the computer to connect to the FPGA board, on which organizing the data according to the standard of PCI-Express protocol, at the same time to cryptographic intervening on the line. Thus, plaintext will be transmitted from the computer to the FPGA board via PCI-Express interface, then it will be organized, cryptographic intervened and transmitted back to the computer. |
