Embodiment Construction
[0055] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all of them. Based on the embodiments of the present application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present application.
[0056] In order to reduce the difference in digital signature operations and simplify the cumbersome steps of digital signature operations when performing security protection on information, in the embodiment of this application, a method of security protection is designed, which allows any browser application to pass The specified protocol sends a digital signature command containing the information to be processed to the security protection a...

The embodiment of the present application discloses a method and device for security protection. The method is that the security protection application program receives a digital signature command sent by any browser application program through a specified protocol, wherein the digital signature command contains information to be processed; The information to be processed included in the digital signature instruction, and the digital signature certificate specified by the user is determined; based on the key contained in the digital signature certificate, any control or plug-in is used to digitally sign the information to be processed to obtain the signature value of the information to be processed ; Send the security information including the signature value to the browser application, triggering the browser application to send the security information to the server. In this way, there is no need to judge the type, version, and number of browser application programs, and the security protection application program uniformly performs digital signatures on the information to be processed, which realizes the consistency of digital signature operation steps and simplifies digital signatures. tedious steps.
Description
technical field [0001] The present application relates to the field of computer technology, in particular to a method and device for security protection. Background technique [0002] With the rapid development of computer technology, in order to improve the security of Internet information transmission, when a user logs in to the system or interacts with important business information, the key contained in the certificate issued by the server is usually used to digitally sign the interactive information , to protect the information security. [0003] The so-called digital signature is based on the local key, using the signature algorithm to calculate the characteristic data of the interactive information to obtain the signature value, so that the server can use the public key to verify the signature value and determine the authenticity and integrity of the user's information . [0004] Under the prior art, see figure 1 As shown, it is a flow chart of a security protectio...
