Abstract
The invention discloses an EPP keyboard with good secrecy performance. The EPP keyboard comprises a keyboard panel, a frame, a plurality of metal keys, a plastic gasket, a keyboard base plate, a keyboard sensing plate, a core circuit board, a core protective cover and a keyboard rear cover, wherein the keyboard panel, the frame, the metal keys, the plastic gasket, the keyboard base plate, the keyboard sensing plate, the core circuit board, the core protective cover and the keyboard rear cover are sequentially arranged from top to bottom, the metal keys are connected with the frame, the keyboard panel is sequentially connected with the frame, the plastic gasket and the keyboard base plate, the keyboard sensing plate is sequentially connected with the core circuit board and the core protective cover, and the keyboard rear cover covers the core protective cover and the plastic gasket and is connected with the keyboard base plate. The keyboard has the advantages that the disassembling difficulty is large, the anti-attack capability is strong, data safety is good, the risks of information leakage and property damage of a cardholder are reduced, and it is ensured that money in an account of the cardholder is not prone to being stolen.
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...
