Abstract
Examples described herein relate to deferred authentication in secure boot systems. An untrusted component is identified in a boot sequence in a trusted execution environment. A secure boot authentication of the untrusted component is deferred for a predetermined period and access to hardware resources is restricted. An image digest and privilege rights including access to hardware resources associated with the untrusted component is obtained in an untrusted execution environment. A request including the image digest and the privilege rights is sent to a central node over a secure connection. A response including a signature based on image digest and approved privileges is received from the central node. The untrusted component is authenticated in the trusted execution environment using the signature before expiry of the predetermined period. Access to the hardware resources is provided to the untrusted component in the trusted execution environment based on the approved privileges.
