Abstract
A method and system for public key infrastructure (PKI) in software defined vehicles enables secure communication between electronic components. The method includes establishing trust between multiple electronic components through a certificate history comprising signed public keys stored on each component. Once trust is established through attestation between components, the method utilizes signed Diffie-Hellman key exchange to securely distribute symmetric keys to the trusted components. These symmetric keys enable authenticated communication between the components to control vehicle systems and functions. The system operates locally without requiring internet connectivity or specialized service tools, allowing for secure field replacement and upgrading of components while maintaining system security through verification of component authenticity and prevention of counterfeit hardware.
