The present invention is directed to field of electronic circuit protection, and especially to a security protection box which can protect elements on a circuit board against being attacked.
Nowadays, some high sensitive data information stored in the electronic circuit, such as bank information, passwords, poll code and so on, is often attacked and embezzled without any authorization. Therefore, more and more attention is paid to protect these data, and so all kinds of protection devices and methods are presented continuously. Among these methods, a method, which is relatively effective to prevent the sensitive data information from being attacked without any authorization, is used to prevent the sensitive data information from being embezzled by memorizing a software for encrypting or decrypting the sensitive program or data in a memory device. However, this approach relies on keys of encryption and decryption memorized in the memory device, which also require physical and electronic protection to avoid being attacked easily.
An object of an embodiment of the present invention is to provide a security protection box, which intends to settle the problem of the sensitive data information of elements in the electronic circuits being embezzled by physical means.
The embodiment of the present invention is carried out in this way: a security protection box for enclosing a protected region of a protected circuit board so as to protect the elements in the protected region. The security protection box includes a circuit board. The circuit board with a thin center and a thick periphery forms a box shape, and is provided with circuit routing layers. The circuit routing layers trigger associated circuit to erase or destroy the information in the elements in the protected region when the circuit routing layers are physically attacked.
The present invention protects the elements in the protected region through covering the protected region in the protected circuit board with a box-shaped circuit board, which has thin center and thick periphery and is disposed on the protected circuit board.
Objects, technical schemes and advantages of the present invention will be more apparent from the following detailed description of the embodiments with reference to the accompanying drawings. However, it is to be appreciated that the following description of the embodiments is merely to explain the present invention and is no way intended to limit the present invention.
The embodiment of the present invention is to enclose the important elements on the protected circuit board by providing the box-shaped circuit board with the thin center, thick periphery and the circuit routing layers at a side of the protected circuit board, where attacking usually happens. In case that it happens to destroy the important electronic elements or embezzle the sensitive data information of the electronic elements, the wiring of the security protection box is broken or short-circuit so as to trigger the associated circuit to destroy or erase the sensitive data information of the important elements on the protected circuit board, thereby preventing it from being detected or stolen.
The protected circuit board 10 may be a mainboard of POS (point of sales) machines or the circuit boards used in other devices. Referring to
Herein described embodiments are preferred embodiments of the present invention but it should not be construed as limiting the overall scope of the present invention. It will be apparent that various modifications, replacements and variations may be made in the present invention without departing from the spirit or scope of the present invention.
The present invention is adapted for field of electronic circuit protection and provides a security protection box, for enclosing the protected region of a protected circuit board in order to protect the elements in the protected region. The security protection box comprises a circuit board. The circuit board with thin center and thick periphery forms a box shape, and has the circuit routing layers. The circuit routing layers trigger the associated circuit to erase or destroy the information in the elements in the protected region when the circuit routing layers are physically attacked. The present invention protects the elements in the protected region through covering the protected region on the protected circuit board with a circuit board having thin center and thick periphery.
