Abstract

The invention discloses an EPP keyboard good in safety. The EPP keyboard comprises a keyboard panel, a key frame, a plurality of keys, a silica gel gasket, an upper protection circuit board, a keyboard bottom plate, a main keyboard plate, key conduction columns and a rear keyboard cover, wherein the keyboard panel, the key frame, the keys, the silica gel gasket, the upper protection circuit board, the keyboard bottom plate, the main keyboard plate, the key conduction columns and the rear keyboard cover are sequentially arranged from top to bottom, the keys are connected with the key frame, and the number of the key conduction columns is the same as that of the keys. The silica gel gasket is provided with a plurality of protrusions matched with the keys. The positions, corresponding to the protrusions, of the upper protection circuit board and the keyboard bottom plate are provided with through holes used for installing the key conduction columns. The through holes of the keyboard bottom plate are shaped like step holes with the inner diameter of the lower portions being large. Baffles used for being cooperatively connected with the lower portions of the step holes are arranged at the lower portions of the key conduction columns. 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 machines (ATMs) security protection, in particular to an EPP keyboard with good security and strong ability to resist external attacks, and transaction information inside the EPP keyboard is difficult to be stolen. 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 is an urgent need to develop an ...
