Post-Quantum Secure Remote Password Protocol from RLWE Problem [chapter]

Xinwei Gao, Jintai Ding, Jiqiang Liu, Lin Li
2018 Lecture Notes in Computer Science  
Secure Remote Password (SRP) protocol is an augmented Password-based Authenticated Key Exchange (PAKE) protocol based on discrete logarithm problem (DLP) with various attractive security features.  ...  An important line of key exchange protocols that can defeat such attack is authenticated key exchange (AKE).  ...  These are major advantages of SRP compared with other PAKE protocols. SRP is also a key exchange protocol which provides mutual authentication and forward secrecy.  ...

Privacy, Discovery, and Authentication for the Internet of Things [article]

David J. Wu and Ankur Taly and Asim Shankar and Dan Boneh
2017 arXiv   pre-print
Our protocols provide private and authentic service advertisements, zero round-trip (0-RTT) mutual authentication, and are provably secure in the Canetti-Krawczyk key-exchange model.  ...  In contrast to alternatives, our protocols are lightweight and require minimal modification to existing key-exchange protocols.  ...  We thank Bruno Blanchet for his help in verifying the unlinkability property of our modified private mutual authentication protocol in Section 4.  ...

The Whole is Less Than the Sum of Its Parts: Constructing More Efficient Lattice-Based AKEs [chapter]

Rafael del Pino, Vadim Lyubashevsky, David Pointcheval
2016 Lecture Notes in Computer Science  
Authenticated Key Exchange (AKE) is the backbone of internet security protocols such as TLS and IKE.  ...  This is advantageous when signing relatively long messages, such as the public keys and ciphertexts generated by a lattice-based KEM.  ...  A's knowledge of the signature key of Party 1 has no incidence on this proof. This implies that an active adversary will cause an abort before the third flow.  ...
