Embodiment Construction

[0012] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0013] The safety protection device of the embodiment of the present invention encloses the area where important components are set on the protected circuit board through a protection board with circuit wiring and a protection wall. Once there is an attempt to destroy these components or steal sensitive data information on these components When it is necessary to break through the protection wall or protection board of the safety protection device first and not cause the wiring on it to be disconnected or shorted, otherwise, the relevant circuit will trigger, destroy or erase the sensitive data info...

Abstract

The invention provides a safety protection device, comprising a protection board and a protection wall, wherein the protection wall and the protection board are combined together to form a cover with an opening at only one side so as to shield a protection area of a protected circuit board. The invention is characterized in that the protection wall is surrounded by at least two combined independent circuit lathes, the circuit lathes are provided with through holes, and conductive zebra strips are mounted in the through holes and physically contacted with the protection board, the protection board is electrically connected to the protected circuit board by means of the conductive zebra strips, a fixing hole is arranged on each circuit lath, and the protection board is provided with the fixing hole corresponding to the fixing hole of the circuit lath, the protection board is located by a bolt through the fixing holes of the protection board and the circuit lath. The invention surrounds the protection area of the protected circuit board by the protection board and the protection wall that is surrounded by at least two combined independent circuit lathes, thus providing the protection for the components in the protection area and preventing the components from physical attacks.

Description

technical field [0001] The invention belongs to the field of electronic circuit protection, in particular to a safety protection device 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 are constantly emerging. Among them, a more effective way to prevent sensitive data from being attacked without authorization is to encrypt and decrypt sensitive data by storing it in a memory device. 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 protected physic...
