Secret Dispersion: Secure Data Delivery in Cyber Physical System
Rui Bo Hu, Yanmin Gong · 2018
In cyber physical systems, the communication infrastructure is faced with multiple challenges such as cyber attacks. In this paper, we propose a scheme for secure data communication in CPS against eavesdropping attacks. Our basic idea is combining multipath routing and secret sharing based on the special condition of CPS. This scheme achieves that even if an adversary compromises some nodes, it would not be able to recover the original data as long as the shares on compromised nodes are less than a predefined threshold. The simulation results demonstrate the effectiveness of our scheme.
