Abstract

Disclosed are systems, methods, and non-transitory computer-readable media for network security using Root of Trust (RoT). A node in the vehicle networking system receives an authentication message from an adjacent node in the vehicle networking system. The authentication message included identifying information of the adjacent node that is digitally signed with a digital signature having been generated using a private key. The adjacent node accessed the identifying information of the second node from a source image authenticated during a secure boot of the adjacent node. The node accesses a public key available to the node and authenticates the adjacent node based on the public key and the digital signature included in the authentication message.
