Title:
SYSTEM FOR CONTROLLING SE, METHOD, AND CHIP
Document Type and Number:
WIPO Patent Application WO/2019/100693
Kind Code:
A1
Abstract:
A system for controlling an SE (11c), a method, and a chip. The system comprises an SE (11c), a processor (11a), a power-on component (11b), a PMU (13), and a communication unit (12); the SE (11c), the processor (11a), and the power-on component (11b) being located in a first semiconductor chip (11); the communication unit (12) being used to receive a communication signal satisfying a preset condition, and output, according to the communication signal, a first power-on signal to the power-on component (11b); the power-on component (11b) being used to trigger the processor (11a) to be powered on; the processor (11a) being used to acquire, from the power-on component, SE (11c) power-on instruction information, and control, according to the SE (11c) power-on instruction information, the SE (11c) to be powered on; the SE (11c) being used to interact secure communication data with the communication unit (12), and perform secure processing of the secure communication data; the PMU (13) being used to supply power to the processor (11a), the SE (11c), the power-on component (11b), and the communication unit (12). In the solution regarding a built-in SE (11c), the system can still trigger, after the processor (11a) is powered off, the SE (11c) to be powered on for secure processing, so as not to affect the use of a security function while saving power as much as possible.
