Abstract
A data message authentication system in a vehicle communication network includes a sequence generator configured to generate a sequence representative of an intra-message pattern; a parsing processor configured to receive a data message, receive the sequence from the sequence generator, select a subset of data segments from the data message based on the intra-message pattern, and output the selected subset of data segments; and a tag generator configured to receive the selected subset of data segments from the parsing processor and generate an authentication code based on the selected subset of data segments, where the authentication code corresponds to the data message.
