Enabling and Optimizing MACsec for Industrial Environments (Extended Abstract)

The specifics of industrial networks make security mechanisms necessary, that are specifically designed for them. This work proposes two modifications for MACsec, a new security protocol for protecting layer 2 traffic: a new fragmentation mechanism enabling MACsec to work within future industrial networks, and the use of ciphers currently not standardised for MACsec, leading to a significant increase in the performance of MACsec.
