Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0032] figure 1 A schematic flowchart of an embodiment of the software protection method of the present invention is shown.

[0033] like figure 1 As shown, the software protection method of the present invention includes that when the server receives the software code segment to be protected from the remote upload, it processes the software code segment into an intermediate code and saves it; When a call request of a segment is made, the intermediate code is executed according to the call request, and an execution result is returned.

[0034] In this embodiment, whenever the server receives a new software code segment uploaded remotely to be protected, it processes the software code segment as an intermediate code and saves it. The server may succes...

Abstract

The invention discloses a software protection method. The method includes the steps: on receiving a software code snippet to be protected and remotely uploaded, a server processes the software code snippet into an intermediate code and stores the intermediate code; on receiving a call request aiming at the software code snippet and remotely transmitted, the server executes the intermediate code according to the call request and returns execution results. The invention further discloses a corresponding software protection system. The software protection method and system has the advantages that software security is higher, no limits on operating systems and hardware occur, and extensibility is high.

Description

technical field [0001] The invention relates to the field of computer software, in particular to a software protection method and system. Background technique [0002] In the field of software protection, the currently widely used software protection method is code transplantation. The usual method of code transplantation is to transplant several code segments necessary for software operation to run in a "safe environment". By hiding part of the code logic of the software in this way, the difficulty of cracking can be increased to the level close to rewriting the software, greatly increasing the The difficulty of cracking realizes the protection of the software. [0003] A traditional "secure environment" is typically hardware-specific, such as a smart card-based dongle. However, in practice, it is found that these security hardwares also have some problems while providing security protection: 1), the performance of security hardware usually cannot match that of a PC, resu...
