This document describes the Quantum-Safe Hybrid ciphersuite, a new cipher suite providing modular design for quantum-safe cryptography to be adopted in the handshake for the Transport Layer Security (TLS) protocol version 1.2. In particular, it specifies the use of the NTRUEncrypt encryption scheme in a TLS handshake.
