2021. Extending the Network Time Security Protocol for Secure Communication between Time Server and Key Establishment Server. 2021 Joint Conference of the European Frequency and Time Forum and IEEE International Frequency Control Symposium (EFTF/IFCS). :1—5.
This work describes a concept for extending the Network Time Security (NTS) protocol to enable implementation- independent communication between the NTS key establishment (NTS-KE) server and the connected time server(s). It Alls a specification gap left by RFC 8915 for securing the Network Time Protocol (NTP) and enables the centralized and public deployment of an NTS key management server that can support both secured NTP and secured PTP.

2020. A Network Time Security Based Automatic Key Management for PTPv2.1. 2020 IEEE 45th Conference on Local Computer Networks (LCN). :144–153.
The PTPv2.1 standard provides new protection mechanisms to ensure the authenticity and integrity of PTP messages. However, the distribution of the necessary security parameters is not part of the specification. This paper proposes a simple and practical approach for the automated distribution of these parameters by using a key management system that enables the Immediate Security Processing in PTP. It is based on the Network Time Security protocol and offers functions for group management, parameter updating and monitoring mechanisms. A Proof-of-Concept implementation provides initial results of the resources required for the key management system and its use.
