Safety connecting method between circuit boards on information safety device

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...

[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.
