A Fault-Tolerant Emergency-Aware Access Control Scheme for Cyber-Physical Systems [PDF]

, 2011
Access control is an issue of paramount importance in cyber-physical systems (CPS). In this paper, an access control scheme, namely FEAC, is presented for CPS. FEAC can not only provide the ability to control access to data in normal situations, but also
