This document proposes an extension to the MPLS pseudowire format to enhance pseudowire user-plane security. The extension, called PWsec, provides confidentiality, data integrity, and source authentication. The extension is based on the National Institute of Standards and Technology (NIST) Advanced Encryption Standard (AES) using the Galois/Counter Mode (GCM).
