A new inexpensive approach for using credentials in a secure manner has become available due to the fact that several types of general-purpose secure hardware, like TPMs, Mshield and ARM TrustZone are becoming widely deployed. These technologies still have limitations, one being the limited on-chip secure memory which leads to severe size constraints for credentials that need to execute in secure memories. In this paper, we describe, in the context of a credential provisioning and execution architecture we call On-board Credentials (ObC), a secure scheduling mechanism for overcoming some of the size constraints imposed for the virtual credentials implemented on ObC.
