Embodiment Construction

[0052] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Apparently, the described embodiments are only some of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of this application.

[0053] In the prior art, the two most important chips of a mobile terminal are a central processing unit and a memory; the former is a very large-scale integrated circuit, which is the computing core and control core of a mobile terminal. Its function is mainly to interpret the instructions of the mobile terminal and process the data in the software of the mobile terminal. The central processing unit mainly includes an arithmetic unit (Arithmetic Logic Unit, ALU) and a high-spee...

Abstract

Embodiments of the invention disclose a chip mutual identification method and device, a storage medium and a mobile terminal. The method is applied to the mobile terminal comprising a processor and amemory, and comprises the steps: obtaining the serial number of the memory when detecting that the mobile terminal is started for the first time; generating a first mutual identification code and a second mutual identification code according to the serial number; writing the first mutual identification code into a processor, and writing the second mutual identification code into a memory; if it isdetected that the mobile terminal is not started for the first time, obtaining a first mutual identification code and a second mutual identification code; inversely solving a first serial number according to the first mutual identification code, and inversely solving a second serial number according to the second mutual identification code; if the first serial number is the same as the second serial number, allowing the mobile terminal to be started; and if the first serial number is different from the second serial number, forbidding starting the mobile terminal. Therefore, other people canbe prevented from maliciously cracking the program, and the program security of the mobile terminal is improved.

Description

technical field [0001] The present application relates to the communication field, and in particular to a chip mutual identification method, device, storage medium and mobile terminal. Background technique [0002] In recent years, with the development of science and technology and the improvement of people's requirements for products, mobile terminals are favored by people because of their diverse functions and small size and easy to carry. The processor of the mobile terminal endows it with diverse functions, and the memory is used to store programs running in the terminal. [0003] In the prior art, there are no protective measures to protect the processor and memory. Once any of the processor or memory is removed from the mobile terminal and installed on the corresponding debugging instrument, there is a risk of maliciously cracking the program through reverse engineering. risk, thereby reducing the program security of the mobile terminal. [0004] Therefore, there are...
