Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only parts related to the present invention are shown in the drawings but not all content.

[0022] The embodiment of the present invention provides a program code protection method, such as figure 1 As shown, the method includes:

[0023] 101. Acquire a program code that needs to be protected and a key program code used to encrypt the program code that needs to be protected.

[0024] Among them, the key code program is used to perform hash calculations to obtain the encryption and decryption keys for encrypting program codes that need to be protected. It can be encrypted program codes or unencrypted (that is, progra...

Abstract

The invention discloses a program code protection method and device, belongs to the technical field of computer terminals and solves the problem that program codes are tampered easily. The method mainly comprises steps as follows: acquiring to-be-protected program codes and key program codes for encrypting the to-be-protected program codes; performing Hash calculation on the key program codes with a preset algorithm to acquire encryption keys; encrypting the to-be-protected program codes by the encryption keys to acquire encrypted program codes. The program code protection method and device are mainly applied to program code tampering prevention processes.

Description

technical field [0001] The present invention relates to the technical field of computer terminals, in particular to the field of system security, and in particular to a program code protection method and device. Background technique [0002] Android is a semi-open source operating system based on Linux, and Linux is a free and open source Unix-like operating system, so crackers can easily use dynamic code injection technology to destroy the original code logic of the Android system and add malicious code logic, making the Android system not functioning normally. Contents of the invention [0003] In view of this, an embodiment of the present invention provides a program code protection method and device to solve the technical problems mentioned in the background art section above. [0004] On the one hand, an embodiment of the present invention provides a program code protection method, the method comprising: [0005] Obtaining the program code that needs to be protected...
