Kernel space measurement

A method comprising: generating, with a device, a nonce; writing, with the device, the nonce to a memory location accessible to a kernel; initializing the kernel; in response to an end of initialization, measuring a specified kernel space to produce a first result; writing the first result to a regi...

Summary:A method comprising: generating, with a device, a nonce; writing, with the device, the nonce to a memory location accessible to a kernel; initializing the kernel; in response to an end of initialization, measuring a specified kernel space to produce a first result; writing the first result to a register of a second device; writing a location and size of the specified kernel space to a buffer; measuring the buffer; writing a result of buffer measurement to a second register of the second device; requesting a quote from the second device, the quote to include the nonce, the contents of the register, and the contents of the second register; and passing the quote to the device.
