Abstract
Techniques described herein enable the implementation of a secure driver framework. In one example, a method includes managing an unsecure operating system execution environment comprising a first user mode and a first kernel mode. The method can also include managing a secure execution environment comprising a second user mode and a second kernel mode, and executing a secure driver within the second user mode of the secure execution environment in response to a system call from an unsecure driver in the first kernel mode or the first user mode, wherein the secure driver enables the unsecure driver to communicate with a secure device. Furthermore, the method can include providing one or more system services of the second kernel mode to the secure driver.
