    abstract =  {This document extends RFC 4279, RFC 4492, and RFC 4785 and specifies a set of cipher suites that use a pre-shared key (PSK) to authenticate an Elliptic Curve Diffie-Hellman exchange with Ephemeral keys (ECDHE). These cipher suites provide Perfect Forward Secrecy (PFS). This memo provides information for the Internet community.},
