Safety connecting method between circuit boards on information safety device

Abstract

A method for safely connecting circuit boards on an information security device, wherein 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 an encryption processing module, The action of the encryption processing module can be triggered by the safety detection module to ensure information security. The electrical connection between the circuit board and other circuit boards uses a conductive rubber connector, and the conductive rubber connector is connected to at least one of the two connected circuit boards. Movable connection, the conductive rubber connector is positioned through a frame that can be fixed on one of the circuit boards, the safety detection module on the circuit board containing the encryption circuit cooperates with the safety detection device on the other circuit boards to be connected , can detect whether the safety connection between two circuit boards is broken. The strong anti-attack capability provides the possibility to facilitate the internal circuit distribution of information security equipment and ensure the effective implementation of information security measures.

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...

[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.
