Naiara Moreira, Jesús Lázaro, Jaime Jiménez, Mikel Idirin, Armando Astarloa · 2015
The limitations of Annex K, as defined in the second version of IEEE 1588 standard, lead the standardization committee to evolve from an integrated security solution to a set of internal and external security mechanisms. The aim of the group is to address different requirements and deployment paradigms of application specific profiles. In this paper, a comparative study of the proposed security solutions within the working group is presented. In addition, a new MACsec use case to provide hop-by-hop group security is introduced.
