We analyse AUTOSAR SecOC Profile 3, a solution to provide freshness for authenticated messages, and further propose an extension of this security profile that copes with the limitations identified in our analysis. The extended profile provides a faster resynchronisation of the freshness value and consumes less bandwidth due to the reduction of the number of synchronisation messages needed. We evaluated our solution based on two demonstrators, one communicating via CAN bus and one communicating over Ethernet. Read more.
