Embodiment Construction

[0024] Describe in detail below in conjunction with the preferred embodiment of the present invention shown in accompanying drawing

[0025] The metal encryption keyboard for ATM terminal that adopts keyboard encryption method of the present invention to realize, comprises the panel that distributes successively from top to bottom, backing plate, gasket, conductive rubber key plate, and key is electrically connected printed circuit board and base, and described panel and The base surrounds a keyboard cavity, which is provided with a printed circuit board for keyboard processing and a power supply battery. There are openings on the panel, and each key protrudes from the opening. The small axis of protection between the boards; the printed circuit board for keyboard processing can be divided into a security function processing part and a non-secrecy function processing part, and the side of the security function processing part where components are placed is closed with a protect...

Abstract

Word of the keyboard said in the invention includes print circuit board for processing keyboard. The invention uses following security measure for the keyboard: print circuit board in use for processing keyboard is divided into a part for processing function of secrecy, and a part for processing not confidential function. A mechanism for protecting secrecy information is setup on the keyboard to surround physical space of the part for processing function of secrecy. Once the mechanism gives signal to show that secrecy information meets with attack, secrecy information inside the part for processing function of secrecy is destroyed. A mechanism for protecting keyboard body is setup on the keyboard. Once the mechanism gives signal to show that keyboard meets with attack, the said secrecy information is also destroyed. The secrecy information includes at least a cipher key, and program run on microprocessor includes DES algorithm. The invention raises data security of keyboard operation.

Description

technical field [0001] The invention relates to financial equipment, in particular to an ATM (automatic teller machine) operating keyboard, in particular to a data security method for the ATM operating keyboard. Background technique [0002] The existing banking system usually consists of three parts: host, terminal and network to form a huge network banking system. Bank key management software is usually installed in the bank host or front-end server, and terminal processing software is installed in the bank terminal. The host and terminal are connected through the network. The data format complies with the ISO8583 standard and has a network encryption mechanism. . From the perspective of the network, this system is quite safe on the surface, but from the perspective of relevant professionals who carry out internal debugging on bank terminals, there are considerable security risks: because in existing bank terminals, such as ATM machines During use, the user's account inf...
