Concealing CAN Message Sequences to Prevent Schedule-based Bus-off Attacks
The work proposes 'Hide-n-Seek,' a novel attack-aware schedule obfuscation strategy for real-time systems like CAN. It hides safety-critical message timing by skipping victim task executions and randomly shifting their instances. This method significantly reduces the success probability of schedule-based attacks, such as bus-off attacks, while maintaining control task performance.
