Abstract: An apparatus has a communication bus, a first circuit, and a second circuit. The first circuit is operational to generate a package, calculate a check value of payload data in the package with a particular cyclic redundance check variant and an obfuscation type, store an encrypted check value in a footer of the package, store an encrypted obfuscation code in a header of the package, and transmit the package on the communication bus. The second circuit is operational to receive the package from the communication bus, decrypt the encrypted check value to determine the check value calculated by the first circuit, determine an obfuscation type from the encrypted obfuscation code, perform a payload verification of the payload data with the particular cyclic redundancy check variant with the obfuscation type applied and the check value, and signal that the payload data is valid in response to passage of the payload verification.

Abstract: A method for attestation of electronic components includes operating a system including the components. The components are configured for electronic communication with each other. A first electronic component provides plug-in hardware and/or configurable software. The method includes utilizing a second electronic component to perform attestation upon the first component using asymmetric key cryptography to verify authenticity. When using the asymmetric key cryptography successfully verifies the authenticity, the method includes selectively enabling one of power or data to the first component and communicating between the first component and the plurality of components to achieve tangible functions. When the cryptography fails to successfully verify the authenticity, the method includes selectively withholding one of power or data connection the first component.

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.

Abstract: A method for public key infrastructure for serviceable electronic components is provided. The method includes identifying a plurality of electronic components in electronic communication with each other and establishing that each of the plurality of electronic components is a trusted device according to a certificate history including a plurality of signed public keys stored upon the respective electronic component. The method further includes utilizing Diffie-Hellman key exchange to distribute symmetric message authentication codes to each of the plurality of electronic components and communicating between the plurality of electronic components with the symmetric message authentication codes to achieve tangible functions that may be provided by the plurality of electronic components.
