Abstract

The invention provides a dual-system dormancy and awakening method and device, equipment and a storage medium, and relates to the technical field of computers. The method comprises the following stepsthat: a computing master core notifies a computing slave core to execute core closing based on a universal operating system; the computing master core executes a first dormancy instruction on the universal operating system to obtain a first dormancy identification value; the computing master core sends the first dormancy identification value to the trusted core, so that the trusted core executescore closing according to the first dormancy identification value and obtains a second dormancy identification value; and the computing master core receives the second dormancy identification value from the trusted core, and performs dormancy operation on the universal operating system according to the second dormancy identification value. Dormancy of the universal operating system and the secureoperating system is realized.

Description

technical field [0001] The present disclosure relates to the field of computer technology, in particular, to a method, device, device and readable storage medium for dual-system sleep and wake-up. Background technique [0002] The central processing unit (Central Processing Unit, CPU) creates a separate address space for each process through memory mapping to isolate the code and data of multiple processes, and isolates the operating system and users through different privilege levels in kernel space and user space. Process code and data. However, since the code and data in the memory are plain text, it is easy to be peeped by other applications in the same memory. Therefore, an extended security module appears. The application sends the encrypted data to the security module, and the security module returns the result after processing. corresponding application. [0003] In the related art, the hardware and software resources of the computer are divided into a secure world...
