IEEE 802.1AE-2018/Cor 1:2020

Corrigendum Standard - Active.
How all or part of a network can be secured transparently to peer protocol entities that use the MAC Service provided by IEEE 802(R) LANs to communicate is specified in this standard. AC security (MACsec) provides connectionless user data confidentiality, data frame integrity, and data origin authenticity. (The PDF of this standard is available at no cost compliments of the IEEE GET program at https://ieeexplore.ieee.org/browse/standards/get-program/page/series?id=68)

Replace Figure 9-4 with Figure 9-4 from IEEE Std 802.1AE-2006.
This standard will facilitate secure communication over publicly accessible LAN/MAN media for which security has not already been defined, and allow the use of IEEE Std 802.1X, already widespread and supported by multiple vendors, in additional applications.
