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 ? also open new vulnerabilities to the system, including the underlying service of clock synchronization. This paper takes a look at the vulnerabilities and attacks against the clock of synchronized nodes. Special focus is set on hardware-oriented and non-cryptographic measures.}, owner = {albert}, timestamp = {2006.11.13} }
