3.3 MACsec (IEEE 802.1AE)

MACsec is a PHY-level security standard that encrypts and authenticates each Ethernet frame. Only trusted devices with the correct MACsec keys can read traffic, preventing tampering and eavesdropping. The radar SoC must also implement the MACsec key agreement (MKA) service for authentication and key management.
