A chip self-destruction circuit and a destruction method based on the chip self-destruction circuit

Abstract

The present application discloses a chip self-destruction circuit, which is applied inside the chip and includes a control module, a drive module and a load module connected in sequence, one end of the load module is grounded, and the other end is connected to the drive module; wherein: The control module is used to output a high level, so that the self-destruction circuit of the chip is turned on; the load module is used to form a current in the circuit when the self-destruction circuit of the chip is turned on; the driving module Used to burn the chip when the current flows. The application also discloses a destruction method based on a chip self-destruction circuit, which is used to solve the problem of low destruction efficiency and high hardware cost in the prior art of externally connecting a physical destruction circuit or using a special physical destruction device to destroy a chip. The problem.

Description

technical field [0001] The present application relates to the field of chip design technology and the field of information security technology, in particular to a chip self-destruction circuit and a destruction method based on the chip self-destruction circuit. Background technique [0002] With the application and popularization of electronic products, chip technology is also developing vigorously. Many important high-tech technical information are stored inside the chip, such as the bank's magnetic card chip, the memory chip of the storage device, etc. These chips have extremely high requirements on information security, and they usually have access rights to perform security verification when they are used. Therefore, when the chip is illegally invaded by a malicious attacker or is required to give up information, it is necessary to activate the destruction device to destroy the chip to ensure information security. [0003] In the prior art, the chip is usually destroye...
