Investigations on Security Aspects in Clock Synchronized Industrial Ethernet
Albert Treytl, Georg Gaderer, Patrick Loschmidt, Nikolaus Kerö · 2006
The synchronization of clocks in distributed systems is an enabling technology for real-time industrial automation applications using Ethernet. Clock synchronization systems are enablers to bring real-time and automation constraints together with well-introduced technologies used in the office and management level. Nevertheless, the architectural advantages of Industrial Ethernet- seamless integration of management and maintenance open also new vulnerabilities to the system including to the underlying service of clock synchronization. This article will have a look at the vulnerabilities and attacks against the clock of synchronized nodes. Special focus is set on hardware-oriented and non-cryptographic measures.
