Embodiment Construction

[0011] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0012] A physical destruction system, the physical destruction system includes a destruction control circuit module and a current limiting protection circuit module, the destruction control circuit module includes a destruction controller and a destruction time control switch, the input power is connected to the destruction time control switch through the current limiting protection circuit module, The destruction controller controls the connection destruction time control switch.

[0013] Based on the above technical solutions and in conjunction with the accompanying drawings, the following specific implementation is given.

[0014] The general power supply voltage for destruction is 28V, such as figure 1 As shown, the destruction control circuit includes a relay for switching on and off the 28V key destruction power supply, a 28V to 3.3V conversion circuit...

Abstract

The invention relates to a physical destruction system, including a destruction control circuit module and a current limiting protection circuit module. When the physical signal destruction is effective, a 28V high voltage large current destruction power supply is directly loaded to a storage medium NAND FLASH chip power supply base pin of a large capacity data storage module by control, and in the manner of reverse high voltage impact or positive large current heating, a storage wafer element of a NAND FLASH chip internal tube core can be completely destroyed. A current limiting protection circuit is designed in the physical destruction process to ensure the physical destruction process does not affect other circuits and only destroy storage FLASH effect. The physical destruction system can physically damage storage FLASH to achieve store data unrecoverability and ensure the complete elimination of important sensitive data in case of emergency.

Description

technical field [0001] The invention relates to a physical destruction system, which belongs to the technical field of data storage and data security. Background technique [0002] The purpose of physical data destruction is to prevent the outside world from seeing the relevant data or it is permanently unrecoverable, so it needs to be treated with caution. At present, different data destruction schemes are adopted in various countries, and the methods are different, mainly including deleting, formatting, and overwriting data. Such as soft destruction method and physical destruction method of high current breakdown FLASH. [0003] The soft destruction method has risks such as long destruction time and recoverability. In an emergency, it is better to choose destructive and non-recoverable physical destruction. Contents of the invention [0004] The purpose of the present invention is to provide a physical destruction system to solve the problems of long destruction time an...
