Embodiment Construction

[0035] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0036] A protection method for a permanent anti-cutting machine of an intelligent POS terminal realized by the present invention is simple in operation, good in use effect, and easy to be widely popularized.

[0037] To achieve the above object, the technical solution of the present invention is as follows.

[0038] The present invention also provides a protection method for a permanent anti-cut machine of an intelligent POS terminal. During the operation of the POS terminal, the method includes the following steps:

[0039] Step 1: Safe start: The POS terminal enables a safe program start when starting;

[0040] Step 2: Customized signature of the security processor SP: the user of the security processor SP sets the authority to use the POS terminal;

[0041] Step 3: Power-on identity verification unit: the POS ter...

Abstract

The invention discloses a protection method for an intelligent POS terminal permanent anti-cutting machine. In the invention, the security processor (hereinafter referred to as SP) custom signature is to prevent the compiled SP firmware from being illegally tampered with or replaced, tamper-proof The implementation is to calculate the hash value of the compiled firmware program, then sign it with the signed private key, and pack the signed information into the firmware. The implementation of anti-replacement is to configure the SP internal Flash lock protection when the SP firmware compiles the code, so that the security program in the SP internal Flash cannot be read or rewritten by the outside. SP verifies the authenticity and integrity of the firmware with a solidified security program during startup.

Description

technical field [0001] The invention belongs to the technical field of POS machine information security, and in particular relates to a protection method for an intelligent POS terminal permanent anti-cutting machine. Background technique [0002] Cutting machine means that in order to obtain illegal benefits, criminals use technical means to replace the POS terminal program placed in the hands of merchants with a system or program connected to the operation and maintenance background of other companies, which greatly damages the operation and maintenance of the background. interests of businessmen. Cutting machines are mainly divided into permanent cutting machines and runtime cutting machines. Permanent shutdown means that the POS terminal operating system is completely replaced with another system, and any operation can be performed on this system; runtime shutdown refers to uninstalling or deleting the original merchant’s application program without replacing the operat...
