Abstract
In various examples, a technique for securely transmitting CAN (Controller Area Network) messages is disclosed that includes receiving, using a cryptographic engine, a message from an application to be transmitted over a CAN (Controller Area Network) bus, wherein the cryptographic engine executes a secure firmware and is implemented on an on-die discrete processor. The technique further includes accessing, using the secure firmware, a key from a plurality of keys associated with an authentication process from a secure memory associated with the cryptographic engine. Additionally, the technique includes computing an authentication tag using the key and the message and transmitting the message with the authentication tag over the CAN bus to a destination address.
