Hi all, We've updated the TLS 1.3 Quantum Safe Handshake draft to use extensions as suggested by DKG in Prague. All comments welcome.
There's an interesting issue here: McEliece keys, which should be permissible, are larger in size (about 2^20 bytes) than the maximum permissible extension size (2^16-1). In order to support McEliece keys it might be worth increasing the maximum extension size to 2^24-1 for TLS 1.3. Is there a strong reason for keeping the maximum size at 2^24-1, other than saving one byte on all the relevant length fields?

Name: draft-whyte-qsh-tls13 Revision: 01 Title: Quantum-Safe Hybrid (QSH) Ciphersuite for Transport Layer Security (TLS) version 1.3 Document date: 2015-09-20 Group: Individual Submission Pages: 18 URL: https://www.ietf.org/internet-drafts/draft-whyte-qsh-tls13-01.txt Status: https://datatracker.ietf.org/doc/draft-whyte-qsh-tls13/ Htmlized: https://tools.ietf.org/html/draft-whyte-qsh-tls13-01 Diff: https://www.ietf.org/rfcdiff?url2=draft-whyte-qsh-tls13-01 Abstract: 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 1.3. In particular, it specifies the use of the NTRUEncrypt encryption scheme in a TLS handshake.
