Embodiment Construction

[0056] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0057]It should be noted that the embodiment of the present invention can be applied to barcode recognition equipment. The data calling method in the present invention will be described in detail below from the perspective of the data calling device. The data calling device can be a server or a device in the server. functional unit. Among them, the data call device can be divided into an application call layer, a reinforcement layer and a dynamic link library layer. The dynami...

Abstract

The embodiment of the invention discloses a data calling method and a data calling device, which can increase the difficulty of cracking the core dynamic link library. The method includes: receiving a call request for calling a target dynamic link library of a barcode recognition device through a restricted interface; judging whether the call request needs to be verified based on a random algorithm; when the call request needs to be verified, obtaining an access key through a proxy function; Set the private key of the encryption algorithm to decrypt the access key to obtain the decryption result; verify the decryption result and the value of the random factor to verify whether it is legal to use the restricted interface to call the target dynamic link library; when the verification is successful, then It is determined that it is legal to use the restricted interface to call the target dynamic link library; based on the proxy function, the index subscript of the target call interface address of the target dynamic link library stored in the target hash table at the current moment is searched; Look up in the column hash table to get the target dynamic link library.

Description

technical field [0001] The invention relates to the communication field, in particular to a data calling method and a data calling device. Background technique [0002] In the context of today's information age, many companies have begun to increase research and development efforts due to domestic industrial upgrading. In this context, it is particularly important to have core technologies. [0003] In the barcode recognition industry, the core technology is the barcode recognition algorithm, and the mainstream of such algorithms is provided through dynamic link libraries. With the advancement of decompilation technology, such as the famous Interactive Disassembler Professional (Interactive Disassembler Professional, IDA) and other decompilation software upgrades, when strengthening the dynamic link library, usually focus on encryption methods, device binding and other aspects. [0004] However, such an approach will pay less attention to the impact of disassembly on the dy...
