IEC61850 SV and PTP traffic under GNSS time synchronization attacks

During GNSS attacks on a time server in an electrical substation, the time service is affected. These data show how IEC 61850 Sampled Values and IEEE 1588 Precision Time Protocol traffic behaves under these attacks. This is the complementary data for the paper: "Compromising Synchrophasor Data by Attacking Time Synchronization: A Hardware-Lab Study" by Fruböse, C. et al. (2026). This data packet comprises the GNSS spoofing attacks. The jamming attacks can be found at: (DOI) 10.35097/2en2xs4njx2ecbru. The pcap data has been recorded in the KASTEL Security Lab Energy at Karlsruhe Institute of Technology, Karlsruhe (Germany).
