摘      要：To accommodate modern applications,vehicles have become increasingly *** we get benefit from it,the problem of Cybersecurity becomes more and more ***,we have more and more security and privacy challenges for the design of automotive applications and *** known that threat analysis and risk assessment is the key point in the security life cycle,in this paper,we propose a method of threat modeling and risk assessment in automotive ***,we find the vulnerability and threat of automotive system from existing ***,combining stochastic Petri net with Markov chain,we come up a method for probabilistic risk *** the method,we can analyse and evaluate the system by four ***,a case study of the firmware update is *** indicates that this method is efficient.
