Embodiment Construction

[0046] In order to verify the feasibility of the plan, you can input the Beidou navigation information to the authentication information generation part of the system, get the navigation message with the authentication information, and back up the navigation message, one without modification, and the other modified to simulate the deception process, Then send these two messages to the authentication part of the system respectively to verify whether the system can judge the correct navigation information.

[0047] In order to show the effect more directly, the scheme of the present invention uses the OpenSSL library and VisualStudio to conduct experiments. The system environment used in the experiment is Windows 10 system, the processor used is Intel i7-6700, the memory environment is 32G, and the solid-state hard disk SSD is used for the experiment. Data read and write. The specific implementation is as follows, and the data are all expressed in hexadecimal.

Abstract

The invention relates to the technical field of information safety, and provides a Beidou second-generation navigation message digital signature anti-cheating scheme based on domestic passwords. A Beidou second-generation satellite navigation system in China is lack of research in the aspect of information anti-cheating, and a domestic cryptographic algorithm which is developed independently in China is adopted by the scheme, so that the authenticity and integrity of Beidou signals are guaranteed, and the purpose of anti-cheating of satellite signals is achieved. According to the method, secret key management of a public key is carried out through SM4, SM3 provides abstract information for a digital signature generated by a SM2, SM2 domestic asymmetric elliptic curve public key cryptographic algorithm is used for generating the digest information, and the digital signature receiver can authenticate the abstract through the public key to verify whether Beidou second-generation navigation message is deception. The method is effectively utilized in the field of information system safety, and experiments show that the code scheme can be realized through a computer information processing module through an OpenSSl and VisualStudio combined pair scheme, and the experiment result shows that the safety of the Beidou second-generation navigation message can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of information security, and is an anti-spoofing scheme for a Beidou second-generation navigation system based on a domestic password. Background technique [0002] At present, the global satellite navigation system is widely used, and the safety of navigation information is also 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, causing deviations in positioning information. There are reserved information bits in the navigation message frame structure of the Beidou second-generation navigation system, which can be filled with authentication information. This provides the basis for the realization of the solution of the present invention. [0003] Internationally, ECDSA (elliptic curve digital signature) and RSA algorithms are the most commonly used digital signature algori...
