Beidou second generation navigation telegraph text anti-spoofing hardware platform realized based on Verilog language

Abstract

The invention discloses a beidou second generation navigation telegraph text anti-spoofing FPGA hardware platform written in a Verilog language based on national secrets. At present, most of domesticcryptographs such as SM2, SM3, SM4, and the like are completed by C language software simulation based on OpenSSL library, and relevant development is still lacked in terms of the hardware. Accordingto the beidou second generation navigation telegraph text anti-spoofing hardware platform realized based on the Verilog language, domestic cryptographic algorithms SM2, SM3 and SM4 are realized on FPGA chips of Virtex4 and Virtex5 by using the Verilog language, a joint simulation experiment is conducted through ISE and ModelSim, and hardware signature authentication schemes of the beidou second generation navigation telegraph text are completed. According to the beidou second generation navigation telegraph text anti-spoofing hardware platform realized based on the Verilog language, great innovation is realized on the hardware design, BlockRAM is used, and the most central parts of dot product and modular product in an SM2 elliptic curve digital signature algorithm are finished by an embedded type microprocessor. According to the beidou second generation navigation telegraph text anti-spoofing hardware platform realized based on the Verilog language, high data confidentiality and safety level can be provided, and long-time protection is suitable. According to the beidou second generation navigation telegraph text anti-spoofing hardware platform realized based on the Verilog language, encryption authentication in a hardware layer can be conducted on keyframes of a navigation telegraph text, attack methods such as generative type deception and forwarded deception can be effectively prevented, and characteristics of a high detection rate and a low misjudgment rate are provided.

Description

technical field [0001] The invention relates to the technical field of information security, and is a Beidou second-generation navigation message anti-spoofing hardware platform based on an FPGA chip and programmed in Verilog language. Background technique [0002] At present, the global satellite navigation system is widely used, and the safety of navigation information has been paid more and more attention. Our country lacks research on the anti-spoofing of Beidou satellite navigation system information, which can forge or tamper with Beidou satellite signals to make positioning information deviate. The navigation message frame structure of the Beidou second-generation satellite navigation system has reserved information bits, which can be filled with authentication information. This provides the basis for the realization of the solution of the present invention. [0003] Internationally, ECDSA, the Elliptic Curve Digital Signature Algorithm, is mostly used to design aut...
