    abstract =  {This document specifies an automatic key management service for the integrated security mechanism (prong A) of IEEE Std 1588™-2019 (PTPv2.1) described there in Annex P. This key management follows the immediate security processing approach of prong A and extends the NTS Key Establishment protocol defined in IETF RFC 8915 for securing NTPv4. The resulting NTS for PTP (NTS4PTP) protocol provides a security solution for all relevant PTP modes and operates completely independent of NTPv4.},
