Embodiment Construction

[0024] See Figure 1 to Figure 4 . The anti-tamper switch of the present invention includes a circuit board 1 and conductive glue 2 . in:

[0025] The circuit board 1 is provided with an inner ring 11 , a middle ring 12 surrounding the inner ring and an outer ring 13 surrounding the middle ring. The inner ring 11 , the middle ring 12 and the outer ring 13 are all conductive pads.

[0026] In this specific embodiment, the inner ring 11 is a solid square shape.

[0027] The middle ring 12 is composed of a plurality of separated and paired pads 120 , and two pads form a group of signal switches. In this specific embodiment, the middle ring 12 is divided into 8 pads, and adjacent pads form a group of signal switches, which constitute four groups of signal switches: signal switch 121 , signal switch 122 , signal switch 123 and signal switch 124 .

[0028] The outer ring 13 is mainly used to prevent short-circuit attack. The inner ring 11 and the outer ring 13 are grounded.

Abstract

The invention discloses a tamper switch and a financial machine, and aims to provide the tamper switch which can prevent drilling attack and is safe. The tamper switch comprises a circuit board and a conductive adhesive, wherein an inner ring, an intermediate ring surrounding the inner ring and an outer ring surrounding the intermediate ring are arranged on the circuit board; the intermediate ring consists of a plurality of bonding pads which are separated and are paired; each pair of bonding pads form a group of signal switch; the conductive adhesive comprises an inner conductive layer pressed on the inner ring, an intermediate conductive layer pressed on the intermediate ring and an outer conductive layer pressed on the outer ring; and the intermediate conductive layer is separated into a plurality of intermediate conductive layers and are pressed on each group of the signal switch one by one. The temper switch can be used for financial industries, such as banks and securities, needing to encrypt data, and used for protecting sensitive information such as the account, the currency amount and password of clients.

Description

technical field [0001] The invention relates to financial equipment, in particular to a tamper-proof switch for financial equipment. Background technique [0002] The security situation of financial payment equipment, such as POS, ATM, etc. is becoming more and more severe, 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, power analysis, etc. 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 safety module must be tightly protecte...
