Secure storage with SCSI storage devices

Abstract

A security command protocol provides secure authenticated access to an auxiliary security memory within a SCSI storage device. The auxiliary security memory acts as an authenticated separate secure storage area that stores sensitive data separately from the user data area of the SCSI storage device. The security command protocol is used to access the auxiliary security memory. The security command protocol allows a trusted execution environment to transport sensitive data to and from storage in the auxiliary security memory. The regular execution environment does not have access to the security command protocol or the auxiliary security memory. The security command protocol and auxiliary security memory eliminate the need for additional secure storage components in devices that provide the security features of firmware TPM.
