This document introduces a new optional Cryptographic Authentication TLV that LDP can use to secure its Hello messages. It secures the Hello messages against spoofing attacks and some well known attacks against the IP header. This document describes how the National Institute of Standards and Technology (NIST) Secure Hash Standard family of algorithms should be used to secure LDP Hello messages.
