Extending crytographic services to the kernel space of a computer operating system

摘要

Cryptographic service software embodied on a hard disc or a floppy disc electronically communicates with a standard operating system of a personal computer. The operating system has an application space and a kernel space. The cryptographic service software performs cryptographic services in the kernel space of the operating system. The cryptographic service software includes a kernel space level application programming interface and a cryptographic service module having a library of encryption algorithms.
