Secret communication method based on FPGA high-speed serial IO

Abstract

The invention discloses a secret communication method based on an FPGA high-speed serial IO. The secret communication method includes the steps of building a data transmission channel in an FPGA chip, allocating the FPGA chip with the data transmission channel at the position where a communication transmitting end is connected in a communication transmission network, allocating the FPGA chip with the data transmission channel at the position where a communication receiving end is connected in the communication transmission network, at the communication transmitting end, transmitting data to be transmitted into the FPGA chip, carrying out primary transmission in the data transmission channel, completing data encryption, then outputting the data from the FPGA chip, enabling the data to enter the communication transmission network, at the communication receiving end, transmitting the data received from the communication transmission network into the FPGA chip, carrying out primary transmission in the data transmission channel, completing data decryption, then outputting the data from the FPGA chip, and enabling the data to enter a communication terminal. By means of the secret communication method, the data transmission rate is improved, and the equipment loads are reduced.

Description

technical field [0001] The invention relates to the technical field of secure communication, in particular to a method for secure communication based on FPGA high-speed serial IO. Background technique [0002] One of the most important characteristics of contemporary communications is the large bandwidth, and with the advancement of technology, the bandwidth is getting larger and larger, and it is currently higher than 10Gbit / s. In recent years, due to the increasing number of information security issues, the confidentiality and security of communications have also become an important issue. In order to increase the confidentiality of communication, the usual practice is to introduce a complex algorithm based on mathematical operations, encrypt the data at the data sending end, convert the plaintext into ciphertext and then transmit it, and decrypt the data at the data receiving end. get the raw data. The commonly used algorithms include encryption and decryption algorithm...
