System on Chip Rejuvenation in the Wake of Persistent Attacks. (arXiv:2301.08018v1 [cs.CR])

To cope with the ever increasing threats of dynamic and adaptive persistent
attacks, Fault and Intrusion Tolerance (FIT) is being studied at the hardware
level to increase critical systems resilience. Based on state-machine
replication, FIT is known to be effective if replicas are compromised and fail
independently. This requires different ways of diversification at the software
and hardware levels. In this paper, we introduce the first hardware-based
rejuvenation framework, we call Samsara, that allows for creating new computing
cores (on …
