We present nQUIC, a variant of QUIC-TLS that uses the Noise protocol framework for its key exchange and basis of its packet protector with no semantic transport changes. nQUIC is designed for deployment ...
It uses a fixed key exchange algorithm, compromising agility for implementation and verification ease. nQUIC provides mandatory server and optional client authentication, resistance to Key Compromise Impersonation ...

To reduce confusion and encourage practical development, major standards bodies including IEEE, ISO/IEC and the IETF have worked towards standardizing PAKE schemes, with mixed results. ...
Challenges have included contrasts between heuristic protocols and schemes with security proofs, and subtleties in the assumptions of such proofs rendering some schemes unsuitable for practice. ...
This method is based on a Diffie-Hellman scheme with the server storing a password-derived Diffie-Hellman public key. ...

In general, two ways can be considered for this; 1) to agree on a new group key, and 2) to reuse the established group key which is used before merging. ...
When nodes of each cluster have already agreed on their own group keys and intend to merge themselves for further secure communications, our scheme can be used in an efficient and secure way. ...
