REAL-TIME DISTRIBUTED AUTOMOTIVE SYSTEMS
ABSTRACT
Security has become a critical issue for automotive electronic systems. To protect against
attacks, security mechanisms have to be applied, but the overhead of those mechanisms may
impede system performance and cause violations of design constraints. To remedy this problem,
we proposed an integrated mixed integer linear programming (MILP) formulation that is the first
to address both security and safety constraints during system mapping for controller area
network (CAN) based systems [10]. However, its signal-based security constraints do not fully
reflect real security requirements, and its objective function is to minimize functional path
latencies rather than minimize security risk. Furthermore, its MILP-based approach has high
computation complexity. In this work, we present a new formulation that defines path-based
security constraints and minimizes security risk directly, and propose a new heuristic algorithm
to solve the formulation efficiently. Experiments on an industrial example show that our new
algorithm achieves comparable solution quality as the MILP-based approach with much better
efficiency.](https://image.slidesharecdn.com/security-awaremodelingandefficientmappingforcan-basedreal-timedistributedautomotivesystems-150727045529-lva1-app6892/85/security-aware-modeling-and-efficient-mapping-for-canbased-realtime-distributed-automotive-systems-1-320.jpg)
