Abstract

The invention relates to an encryption keyboard, in particular to an encryption keyboard with a front prying detection protection system. The encryption keyboard comprises a panel and a master control board, wherein a sealing flexible circuit board is also arranged between the panel and the master control board; the inside of the sealing flexible circuit board is provided with an anti-spying detection circuit; the anti-spying detection circuit is led to the surface of the sealing flexible circuit board by a circuit pin, and is electrically connected with a control circuit which has the self-destruction function of the master control board by the circuit pin; the encryption keyboard also comprises a split-type key granule; the key granule comprises a key cap and a pressing column; the key cap comprises a cap top and an accommodating space which is positioned at the lower surface of the cap top and is provided with a downward opening; and the key cap is sleeved on the pressing column by the accommodating space, and the pressing column is in clearance fit with the accommodating space wall.

Description

technical field [0001] The invention relates to an encryption keyboard, in particular to an encryption keyboard with a positive detection protection system. Background technique [0002] Since the hard encryption keyboard of the bank self-service equipment is responsible for the input and encryption processing of the user's bank password, the bank's work key and master key are also stored in the core processing part of the keyboard. In order to achieve ulterior motives, some criminals often steal user passwords by prying or spying on the keyboard, and even decipher the bank's work key and master key to achieve the ambition of stealing bank information, directly threatening users and bank information, Security of Funds. [0003] Encrypted keyboards are generally equipped with a probe detection protection structure and a probe detection protection circuit. When the keyboard encounters a physical probe, the probe detection protection circuit outputs a self-destruct signal to r...
