IEEE Standard for Local and metropolitan area networks-Media Access Control (MAC) Security Amendment 4: MAC Privacy protection
2023
This amendment specifies a MAC Privacy protection encapsulating protocol and its use in conjunction with the MAC Security protocol (MACsec) to hide the source and destination MAC addresses of user data frames, and to reduce any correlation between observable frame sizes and transmission timing. This helps to protect user and application identities and to hide the purpose and content of communications. Management of MACsec and privacy protection is supported by YANG models and SNMP MIBs. Privacy considerations for bridged networks are reviewed.
