Secure SMPTE ST 2059 Time Transfer

Nikolaus Kerö, General Manager from Oregano Systems authored with Thomas Kernen/NVIDIA a new publication for the SMPTE Motion Imaging Journal on “Precision Time Protocol for Synchronization in Broadcast-over-IP”. The full paper can be accessed via IEEEXplore .


The authors discuss in their paper four possible PTP Error Conditions that can occur in the network, and offer ways the broadcasting industry can efficiently use and benefit from the new enhancements of the  ST 2059 standard. To make things even more challenging, the four error conditions are not mutually exclusive, and each can occur either permanently and transiently. These failures can occur either inadvertently due to misconfigured or malfunctioning PTP devices somewhere in the network, or be caused deliberately as a result of a malicious attack against the integrity of the timing network. Here, the authors propose basic security countermeasures against malicious attacks.


Not to mention, the Oregano Systems' syn1588® PTP Stack includes the required functions and features required to design such a secure PTP system in a SMPTE environment.
