Embodiment Construction

[0017] like figure 1 As shown, the core module safety area protection structure proposed by the present invention includes a main circuit board 1 and a central processing unit CPU 2 attached to one side of the main circuit board. The design of the main circuit board 1 adopts an 8-layer design, in which the second layer 10 and the seventh layer 11 are MESH grid layers, and all tamper switch circuits are connected to the second layer 10 and the seventh layer 11, which need to be protected The data signals pass through the MESH layer and are routed on the inner layer 3, layer 4, layer 5 and layer 6 of the main circuit board. Between the 7th layer, so as to get the protection of the MESH layer. In addition, the distance between the layers is within 0.2mm, which is very small, so that the outside world cannot attack from the side of the circuit board, so that the data signal is fully secure. Protect.

Abstract

The invention discloses a protective structure for a safe area of a core module, which comprises a main circuit board (1) and a CPU (Central Processing Unit) (2) attached on one side of the main circuit board, wherein the main circuit board (1) is designed into eight layers, the second layer (10) and the seventh layer (11) are MESH layers, all tamper switch circuits are connected to the second layer (10) and the seventh layer (11), and all data wires requiring to be protected pass through the MESH layers and are wired in the internal third, fourth, fifth and sixth layers of the main circuit board. The protective structure is simple in structure and relatively low in cost and accords with the PCI (Peripheral Component Interconnect) standard.

Description

technical field [0001] The invention relates to the security of financial payment equipment, in particular to a core module security area protection structure. Background technique [0002] The security situation of financial payment equipment, such as POS, ATM, etc., is becoming more and more serious, and there are more and more technical attack methods against financial payment equipment, such as using various methods such as opening the cover, cutting, chemical potion corrosion, and power analysis to detect the inside of the equipment. Stored financial transaction keys. To this end, financial payment organizations have defined strict security technology certification standards, called PCI (Payment Card Industry, payment card industry) security certification standards. Only devices that pass the certification standards are considered to meet the security requirements and can resist the current known means of attack. [0003] In the certification standard, the core module...
