Secure Stack for Clocks: Synchronized by IEEE 1588

  title={Secure Stack for Clocks: Synchronized by IEEE 1588},
  author={Bernd Hirschler},
This work analyzes the impact of security protocols on clocks synchronized by IEEE 1588v2. An emphasis is put on high-precision clock synchronziation. The work investigates the security mechanism used to protect the traffic, which carries timing information. A security analyzis performed on Annex K of IEEE 1588v2, the native solution, reveals a fundamental flaw in the protocol, which makes the Precision Time Protocol (PTP) network prone to man-in-the-middle and replay attacks. The security… CONTINUE READING
