Abstract

The invention provides a digital signature verification method and system for security payment. The method comprises the steps: when an online payment terminal is detected in a current verification period, carrying out log recognition on an equipment operation log of a verification server according to a first log recognition model to obtain a plurality of log texts, and carrying out feature extraction to obtain log texts with first feature distribution; obtaining an update log of the equipment operation log after the current verification period, performing feature extraction on the update logto obtain an update log with second feature distribution, and then performing signature message synchronization to obtain a signature verification record; and finally, verifying the dynamic digital signature of the online payment terminal when the online payment terminal initiates the payment request through the established signature verification thread and the signature verification record. Thus,by performing dynamic digital signature verification on the online payment terminal, the legality of the payment request and the security of the payment environment can be judged, thereby avoiding the problems of information loss and information theft when the online payment terminal performs payment.

Description

technical field [0001] The invention relates to the technical field of secure payment and digital signature verification, in particular to a method and system for verifying digital signatures for secure payment. Background technique [0002] With the development of the Internet, online payment has gradually become the mainstream payment method, bringing a lot of convenience to users. However, in actual application, there are some security risks in online payment, such as the loss of payment terminal information. Therefore, how to eliminate these hidden dangers to create a safe online payment environment is very important. Contents of the invention [0003] In order to improve the above problems, the present invention provides a method and system for verifying digital signatures for secure payment. [0004] The first aspect of the embodiments of the present invention provides a method for verifying a digital signature for secure payment, which is applied to a verification...
