Full title: IEEE Standard for Local and metropolitan area networks–Media Access Control (MAC) Security – Amendment 4: MAC Privacy protection
This amendment specified privacy enhancements that complemented existing IEEE Std 802.1AE MAC Security capabilities, reducing the ability of external observers to correlate user data frames, their sizes, transmission timing and transmission frequency with users’ identities and activities. It specified an encapsulation format that allows one or more user data frames and padding octets to be carried within the confidentiality protected data of a consolidating frame, hiding the users’ MAC addresses and original frame sizes. The transmitter can balance the privacy improvement against the loss of efficiency and delay by controlling the sizes of consolidating frames and when they are transmitted. YANG configuration and operational state models were defined both for the functionality previously specified in IEEE Std 802.1AE-2018 and for the functionality added by this amendment. This informative annex describes privacy considerations for the use, design, and deployment of bridged networks.
