An SO file calling method and device

Abstract

The invention discloses a SO file calling method and device. The method comprises the following steps: defining enumeration types E of which enumeration quantities are in one-to-one correspondence with function lists; Defining a global state variable S of which the type is an enumeration type E; When a function calling command is received, firstly obtaining a value S1 of an enumeration amount corresponding to a previous function of a current function in an execution process, and then judging whether the value S1 is equal to a value of a global state variable S or not; If yes, assigning an enumeration variable corresponding to the current function to the global state variable S, and executing a function calling command to call the current function; And if not, terminating the application program. According to the technical scheme provided by the invention, an attacker can be prevented from directly utilizing the interface provided by the SO file to steal the user data, and the SO file is protected from being illegally called. The invention further provides an SO file calling device, electronic equipment and a computer readable storage medium which have the above beneficial effects.

Description

technical field [0001] The present application relates to the field of SO file invocation, and in particular, relates to a method, device, electronic device and computer-readable storage medium for SO file invocation. Background technique [0002] With the popularization of smart phones, various applications gradually enter people's work, life, and entertainment, and financial and payment-related applications are also widely used. This also brings about security problems. Attackers can analyze the code of the application to find loopholes, make viruses, and steal user information. Effective protection of the application code can improve the security of the application. In order to improve the security of the software, application developers often implement the core logic of the application in the native layer and compile it into a shared object (Shared Object, SO). files, so protecting SO files can effectively protect the security of applications. [0003] The relevant SO ...

Problems solved by technology

[0004] However, the disadvantage of this technology is that the attacker does not need to fully understand the processing logic of the application, and can directly obtain the application data or destroy the application by calling the method of the SO file.
