Title:
FUNCTION PROTECTION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/093687
Kind Code:
A1
Abstract:
The present application provides a function protection method and apparatus. The method comprises: a first function to be protected corresponding to a first virtual instruction and a second virtual instruction; executing the first virtual instruction by means of a first dispatcher; and executing the second virtual instruction by means of a second dispatcher, wherein the first dispatcher and the second dispatcher are different. According to the method, by enriching the internal structure of a virtual machine (i.e., preconfiguring multiple dispatchers in one virtual machine), diversifying the jump process in the virtual machine, and dispersing convergence points, the difficulty of reverse analysis and attacks is increased, thereby improving the security of virtualization protection.
