Problems solved by technology

[0002] On the one hand, there are various ways to connect circuit boards to each other. The common ones are direct connection with matching connectors, or connection through an adapter cable. However, these connections are not secure, that is, they cannot effectively prevent intentional attacks.
On information security equipment, in order to ensure that the information processed internally is not leaked, the circuit that needs to be encrypted and the safety detection circuit are usually protected with a physical structure, or several separate circuit modules that need to be encrypted are used together. The physical structure is protected, which greatly limits the internal circuit distribution of information security equipment and the effective implementation of information security measures.

Embodiment Construction

[0027] Below in conjunction with the best embodiment shown in the accompanying drawings, it will be further described in detail.

[0028] In the secure connection method between circuit boards on the information security device of the present invention, the circuits on the information security device are distributed on more than two circuit boards, at least one of which contains an encryption circuit, and the encryption circuit includes a security detection module and a circuit board. The encryption processing module can be triggered by the safety detection module to ensure information security. The electrical connection between the circuit board containing the encryption circuit and other circuit boards uses a conductive rubber connector.

[0029] As shown in Figures 1 to 3, the keyboard with financial transaction information and general information input using the secure connection method between circuit boards on the information security device of the present invention inclu...

Abstract

This invention relates to a safe connection method for CB on an information safety device, on which, circuits are distributed on more than two CB and at least one contains an encryption circuit including a safety detecting module and an encryption process module triggered by the safety detection module to guarantee safety of information, said CB is connected with other CB by a conducting rubber connector movably connected with one of them, the safety detection module is set on the CB containing an encryption circuit to be matched with a safety detection device set on other CB to test if the safe connection between two CB is cut off.

Description

technical field [0001] The invention relates to information security equipment, in particular to a method for safely connecting circuit boards therein. Background technique [0002] On the one hand, there are various ways to connect circuit boards to each other. The common ones are direct connection with matching connectors, or connection through an adapter cable. However, these connections are not secure, that is, they cannot effectively prevent intentional attacks. . On information security equipment, in order to ensure that the information processed internally is not leaked, the circuit that needs to be encrypted and the safety detection circuit are usually protected with a physical structure, or several separate circuit modules that need to be encrypted are used together. The physical structure is protected, which limits the internal circuit distribution of information security equipment and the effective implementation of information security measures to a large extent...
