Chip self-destruction circuit and destruction method based on chip self-destruction circuit

Abstract

The invention discloses a chip self-destruction circuit which is applied to the interior of a chip and comprises a control module, a driving module and a load module, wherein the control module, the riving module and the load module are connected in sequence; one end of the load module is grounded, and the other end of the load module is connected with the driving module; the control module is used for outputting a high level so that the chip self-destruction circuit is conducted; the load module is used for forming current in the circuit when the chip self-destruction circuit is conducted; and the driving module is used for burning the chip when the current flows through. The invention further discloses a destruction method based on the chip self-destruction circuit. The problems that inthe prior art, the destruction efficiency is low and the hardware cost is high in a way that a physical destruction circuit is externally connected or a special physical destruction device is used fordestroying the chip.

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...
