Method and apparatus for encryption, and a non-transitory computer-readable medium that stores instructions for performing encryption. The method includes loading a virtual system driver module in a host operating system and constructing a virtual operating system, wherein the virtual operating system comprises a micro-kernel; preparing and providing context of a processor and a memory page table by the virtual system driver for the micro-kernel, and mapping, in the memory page table, original data and a physical address of a buffer area that receives data after encryption computation is completed; and completing the encryption computation in the virtual operating system and saving the computation result in the buffer area.
