Abstract
A method and system for securing in-vehicle ethernet links are disclosed. According to one embodiment, a method comprises receiving from an authenticator, via an insecure channel, a public key of the authenticator, a random number, and a challenge. A private key of the peer that was supplied to the peer is accessed from local storage at the peer. A state machine computes a session key for the peer, based on the random number, the public key of the authenticator, and the private key of the peer. The state machine computes a peer response to the challenge using the session key for the peer and a symmetric cipher function.
