Embodiment Construction

[0008] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0009] The embodiment of the present invention encloses important components on the protected circuit board by arranging a box-shaped circuit board with a thick middle part and a thick outer periphery and circuit wiring on the vulnerable side of the protected circuit board. Once the act of destroying important electronic components or stealing sensitive data and information on the electronic components occurs, the traces on the safety protection box will be disconnected or short-circuited, triggering the relevant circuit to destroy or erase the protected circuit board Protect sensitive data an...

Abstract

The present invention is applicable to the field of electronic circuit protection and provides a safety protection box used for surrounding the protected area of a protected circuit wafer and providing protection for the components in the area. The safety protection box consists of a circuit wafer. The circuit wafer has thin middle and thick periphery and thus a box shape is formed. Wiring layers are arranged on the circuit wafer. When suffering from a physical attack, the wiring layers trigger the interrelated circuits to erase or destroy the information on the components in the protected area. The present invention protects the components in the protected area by covering a circuit wafer which is thin in the middle and thick in the periphery, on the protected area of a protected circuit wafer.

Description

Technical field [0001] The invention belongs to the field of electronic circuit protection, and in particular relates to a safety protection box for protecting components on a circuit board from attacks. Background technique [0002] Nowadays, some highly sensitive data information stored in electronic circuits, such as bank information, passwords, registration codes, etc., are often attacked and stolen without authorization. Therefore, the protection of these data is getting higher and higher. Various forms of protection devices and methods continue to appear. Among them, a more effective way to prevent sensitive data from being attacked without authorization is to store in a memory device to encrypt and decrypt sensitive data. Program or data software to prevent sensitive data information from being stolen. However, this method relies on the encryption and decryption keys stored in the memory device, and the encryption and decryption keys also need to be physically and electron...
