Abstract


In this paper, a group key based session key establishment protocol is introduced for a secure remote vehicle diagnosis. The proposed scheme aims at providing secure authentication and session key establishment between a vehicle manufacturer server and a group of in-vehicle electronic control unit based on a key graph. The detailed operations of the proposed scheme are provided while providing security analysis results of the proposal. Thanks to the use of the group key, the proposed scheme reduces the number of keys and management cost for the secure remote vehicle diagnosis compared with a traditional scheme that uses a symmetric key cryptosystem.
