Abstract
An input device of a secure authentication protocol system may receive at least one user authentication factor in a pre-boot session. The input device may verify the received authentication factors and may store the verified authentication factors. During a post-boot session, the input device may communicate the verified authentication factor and a stored post-boot session credential received during a prior post-boot session to an authentication engine executing in a trusted execution environment. The authentication engine verifies the received post-boot session credential is logically associated with an immediately preceding post-boot session. Upon successful verification of the received post-boot session credential, the verified authentication factors or data indicative of a successfully verified authentication factor received during the pre-boot session are used in the current post-boot session.
