Chip structure capable of enhancing safety and control method thereof

Abstract

The invention provides a chip structure capable of enhancing safety and a control method thereof. The chip structure comprises a microprocessor, an optical sensor and a D-type trigger, the microprocessor is connected with the optical sensor, and the optical sensor is connected with the D-type trigger; wherein the microprocessor sends an enable signal to open the optical sensor; the light sensor detects and generates a light intensity signal according to the light intensity; the microprocessor receives the light intensity signal, outputs the light intensity signal and stores the light intensitysignal in the D-type trigger, reads the light intensity state of the light intensity signal through the D-type trigger, and controls the working state of the chip according to the light intensity signal, so that the safety of the chip can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of integrated circuit security, and more specifically, relates to a chip structure and a control method for enhancing security. Background technique [0002] With the continuous development of mobile Internet technology, various chips have been widely used in the era of big data. From data storage to data usage to data accounting, security applications of chips are required, especially security chips for protection. In the field of mobile payment, security chips are being widely popularized and applied to protect various data and information security. At present, mobile payment technology has been widely popular and applied all over the world. Mobile payment technology started from satisfying the overseas payment of Chinese tourists, and began to enter other countries and regions from China, bringing convenient, efficient and safe new payment methods to global trade. Create unique "local wallets". Thanks t...

Problems solved by technology

However, the current mobile payment terminals, which use chips, have shortcomings in terms of safe payment, high efficiency and convenience: First, the challenges posed by mobile payment also include personal data security and privacy security issues

Finally, in the field of mobile payment, the scope of use of security chips is still relatively small. There are large loopholes in the security of chips used in the field of mobile payment in the market. The main reason is that the security protection of these chips is mostly based on software security protection technology, while Software protection is easy to crack
