Abstract

The invention is applicable to the electronic circuit field and provides a data security protection device and a secure paying device, wherein the data security protection device comprises a physical shell, which further comprises an uncover self-destruct circuit used for checking the on-state of the physical shell; a microcontroller used for giving out an erasing command when the uncover self-destruct circuit checks that the physical shell is on-state; and a memory cell used for erasing the stored secret data according to the erasing command giving out from the microcontroller. The invention checks the opening action of the physical shell through the uncover self-destruct circuit connected with the microcontroller; and when the physical shell is in an open state, the microcontroller controls to erase the secret data stored in the memory cell connected with the microcontroller, thereby protecting the security of data, lowering the cost and increasing the applicability.

Description

technical field [0001] The invention belongs to the field of electronic circuits, and in particular relates to a data security protection device and security payment equipment. Background technique [0002] During the use of existing secure payment devices, the management of private data such as user keys is involved. In order to store these sensitive private data safely and prevent them from being illegally obtained, the existing technology usually uses expensive physical casings The protection system protects it. However, it is impractical to build an impenetrable physical barrier for most applications. It must be assumed that any level of physical security mechanism will be defeated within a given time, making the cost of secure payment equipment high. And poor applicability. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide a data security protection device, aiming at solving the problem of using an expensive phys...
