Title:
IN-PROCESS ISOLATION METHOD AND APPARATUS, STORAGE MEDIUM, AND COMPUTER PROGRAM PRODUCT
Document Type and Number:
WIPO Patent Application WO/2023/202354
Kind Code:
A1
Abstract:
The present application relates to the technical field of computer security, and discloses an in-process isolation method and apparatus, a storage medium, and a computer program product. During in-process isolation domain switching, first jumping to a trusted isolation domain is carried out, then the security of the current domain switching is detected on the basis of domain switching information in a trusted storage space corresponding to the trusted isolation domain. Neither other isolation domains nor attackers can access the trusted storage space, and therefore, the probability of the domain switching information in the trusted storage space being tampered with is extremely small. Hence, the present solution can effectively prevent vulnerability attacks, and the security is high.
