Abstract

A large number of electronic devices equipped by modern vehicles may become a means for hackers to invade vehicle network system. In order to prevent attacks, it is necessary to introduce the security mechanism of CAN-FD vehicle bus. But CAN-FD uses broadcast message transmission mechanism, lack of security protection, vulnerable to network attacks. Under security constraints, CAN-FD message packaging with low bandwidth occupancy(utilization) is a prerequisite for intelligent application operation in automotive information physics system. On this basis, a signal packaging security constraint that can effectively reduce the hardware cost of Electronic Control Unit(ECU) security design is proposed. In view of the shortcomings of the basic genetic algorithm that it is easy to fall into the local optimal solution prematurely and has poor local ability in the later stage, a hybrid genetic algorithm based on Newton method is proposed, and the local search technology is added to the genetic algorithm. This local search technology is to set up a selection mechanism and selectively use the Newton method to determine whether the algorithm is convergent. The performance of the hybrid genetic algorithm is much better than that of the basic genetic algorithm. The former can overcome the shortcomings of the latter that it is easy to fall into the local optimal solution prematurely and its later local ability is poor. The experimental results show that the algorithm could obtain lower bandwidth utilization, and the influence of the security design on the bandwidth utilization is analyzed by experiments.
