Abstract

As modern vehicles increasingly rely on Ethernet for critical communication, making sure data security against unauthorized access and tampering is imperative. The automotive industry is evolving to meet the growing cybersecurity demands driven by advanced electronic systems and connectivity features. MACsec (Media Access Control Security) provides robust security through encryption and integrity checks, protecting data transmitted over automotive Ethernet networks.

As data transmission speeds and bandwidth requirements in vehicles increase, traditional security measures become insufficient. MACsec addresses these challenges by preventing eavesdropping, replay attacks, and unauthorized device access, thereby enhancing vehicular communication security and contributing to a safer driving experience.
