Problems solved by technology

[0006] However, Scheme 1 relies on the completeness of the QR code virus database and the effectiveness of the security model, however, it is usually difficult to satisfy both
More importantly, it cannot verify the source of the QR code, so it cannot guarantee security
Solution 2 only solves the problem of information leakage and tampering of the QR code, but still cannot prove whether the source of the QR code is reliable

Embodiment 1

[0103] An embodiment of the present invention provides a two-dimensional code authentication method, such as figure 1 As shown, the method includes:

[0104] S101. Obtain a platform digital signature and a second key corresponding to the identity feature information of the issuing terminal, and use the second key to encrypt the first sent content feature value to generate a personal digital signature;

[0105] The platform digital signature is obtained by encrypting the platform identification information with the first key;

[0106] Obtaining the platform digital signature and the second key corresponding to the identity feature information of the issuing terminal includes: sending the first communication identification representing the identity feature of the issuing terminal to the authentication platform; receiving the corresponding first communication key sent by the authentication platform; An identified digital certificate and a second key, the digital certificate carr...

Embodiment 2

[0126] An embodiment of the present invention provides a two-dimensional code authentication method, such as figure 2 shown, including:

[0127] S201. Scan the QR code to obtain QR code information including authentication information, where the authentication information includes a platform digital signature, a fourth key, and a personal digital signature;

[0128] Here, the fourth key corresponds to the identity feature information of the issuing terminal.

[0129] After the scanning terminal scans the two-dimensional code issued by the issuing terminal, information about the two-dimensional code is obtained, wherein the information may be unencrypted two-dimensional code information or encrypted two-dimensional code information.

[0130] When the information is encrypted two-dimensional code information, the key for encrypting the two-dimensional code information is the third key corresponding to the identity feature information of the scanning terminal, and the key for d...

Embodiment 3

[0154] The embodiment of the present invention provides a two-dimensional code authentication method, wherein, in the embodiment of the present invention, the complete process of generating and identifying a two-dimensional code is used as a specific application scenario for the two-dimensional code authentication method in the embodiment of the present invention Be explained. Here, the issuing terminal that generates the two-dimensional code and the scanning terminal that recognizes the two-dimensional code are pre-installed with a client that interacts with the authentication platform, so as to obtain the communication identification based on the issuing terminal or scanning terminal through interaction with the authentication platform The key is used to generate or identify the two-dimensional code, and the root certificate of the authentication platform is installed, that is, the first key to decrypt the digital signature of the platform, so as to authenticate the digital s...

Abstract

The invention discloses a QR code authentication method. The method comprises the following steps: acquiring a platform digital signature and a second key corresponding to identity feature informationof a release platform; encrypting the first sending content feature value through a second key to generate personal digital signature, wherein the platform digital signature is obtained by encryptingthe first platform identification information through the first key; determining authentication information including the platform digital signature, a fourth key corresponding to the second key andthe personal digital signature, and generating a QR code based on the QR code information including the authentication information. The invention further discloses a QR code authentication device anda computer readable storage medium.

Description

technical field [0001] The present invention relates to the technical field of information security, in particular to a two-dimensional code authentication method, device and computer-readable storage medium. Background technique [0002] With the development and popularization of the mobile Internet, the application of QR codes has spread all over the basic necessities of Chinese people. However, while bringing convenience to the lives of the public, its inherent safety hazards cannot be ignored. Security incidents caused by QR codes occur from time to time, which touches the nerves of the public. For example, when a mobile phone user scans a QR code from an unknown source, he may be linked to a malicious website, causing the mobile phone to be infected with a virus or implanted with a Trojan horse, causing unpredictable security risks and economic losses. On the other hand, two-dimensional codes are widely used. If the two-dimensional codes containing user real-name infor...
