An Authentication Scheme Designed for the Lightweight Precision Time Protocol in IoT

The current enhancements in the Internet of things (IoT) standardize a method to precisely synchronize computers or devices over the network. The precision time protocol (PTP) described in IEEE 1588 meets the necessity for higher accurate time synchronization. For achieving higher accuracy, security and resource issues arise. To tackle these issues, an authentication scheme for the lightweight PTP using the digital signature and polynomials is proposed in this paper. The proposed scheme is evaluated through the SimPy simulator and our simulation results show that our proposed scheme can outperform the closely related schemes in the literature.
