EPP keyboard good in confidentiality

Abstract

The invention discloses an EPP keyboard good in confidentiality. The EPP keyboard comprises a keyboard panel, a frame comprising a plurality of key limiting frames, metal keys with the same number as the key limiting frames, a plastic spacer, a keyboard bottom plate, a keyboard sensing plate, a core circuit board, a core protection cover and a rear keyboard cover, wherein the keyboard panel, the frame, the metal keys, the plastic spacer, the keyboard bottom plate, the keyboard sensing plate, the core circuit board, the core protection cover and the rear keyboard cover are sequentially arranged from front to back. The metal keys are arranged in the key limiting frames respectively. The keyboard panel is connected with the frame, the plastic spacer and the keyboard bottom plate sequentially. The keyboard sensing plate is connected with the core circuit board and the core protection cover sequentially. The rear keyboard cover covers the core protection cover and is connected with the plastic spacer and the keyboard bottom plate. The EPP keyboard has the advantages of being large in disassembly difficulty, high in attack resistance and good in data security, lowering the risk of information leakage and property loss of cardholders and guaranteeing that money of the accounts of the cardholders can not be stolen easily.

Description

technical field [0001] The invention relates to the technical field of bank automatic teller machine (ATM machine) safety protection, in particular to an EPP keyboard with strong ability to resist external attacks, and the transaction information inside the EPP keyboard is difficult to be stolen and has good confidentiality performance. Background technique [0002] The EPP keyboard is the cardholder's user data input device installed on the ATM machine. The cardholder needs to enter the PIN code when using the ATM machine for transactions. The EPP keyboard encrypts the PIN code and sends it to the background for verification. [0003] At present, the main means of attacking the EPP keyboard is to install a BUG circuit on the keypad of the EPP keyboard. When the cardholder enters the PIN code through the EPP keyboard, the BUG circuit records the plaintext of the PIN code; thereby stealing the PIN code inside the EPP keyboard. Trading Information. [0004] Therefore, there i...
