    abstract =  {TLS 1.3 {[}I-D.ietf-tls-tls13{]} specifies a signed Diffie-Hellman exchange modelled after SIGMA {[}SIGMA{]}. This design is suitable for endpoints whose certified credential is a signing key, which is the common situation for current TLS servers. This document describes a mode of TLS 1.3 in which one or both endpoints have a certified DH key which is used to authenticate the exchange.},
