Abstract

The invention relates to a dynamic library calling method and device, an electronic device and a storage medium, and the method comprises the steps: searching a dynamic library corresponding to an interface function address according to the interface function address of a first code library, wherein the first code library and a second code library are be pre-compiled into a static library and to be linked to the dynamic library, and the operation of the second code library depends on the interface calling of the first code library; extracting first key data in the dynamic library, and determining a first hash value of the first key data; acquiring a hash signature pre-stored in the dynamic library, and decrypting the hash signature by using a public key corresponding to the hash signatureto obtain a second hash value; and under the condition that the second hash value is the same as the first hash value, executing interface calling corresponding to the interface function address. Through the method and the device, the problem of low security caused by calling of the dynamic library under the unauthorized condition in the related technology is solved, and the technical effect of preventing the dynamic library from being called under the unauthorized condition is achieved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a dynamic library calling method, device, electronic device and storage medium. Background technique [0002] The rapid development of computer and network technology has greatly promoted information interaction. At the same time, computer viruses are constantly evolving and updating along with the development of technology. From the early prank games to today, computer viruses have seriously or threatened people's attention to computers. Therefore, how to prevent virus attacks has become a focus of attention. However, with the development of virus detection technology, the countermeasures against viruses and anti-virus software are also constantly updated. Hooking is a technology that modifies the execution path, and activates the hook processing function by modifying the normal calling process. This technology is used by security software and malicious programs are...
