Modular proofs for key exchange: rigorous optimizations in the Canetti–Krawczyk model

Yvonne Hitchcock, Colin Boyd, Juan Manuel González Nieto
2005 Applicable Algebra in Engineering, Communication and Computing  
Various optimizations in the Canetti-Krawczyk model for secure protocol design are proven to preserve security.  ...  In order to obtain the required proofs, we find it necessary to slightly revise the authenticated links part of the Canetti-Krawczyk model.  ...  Conclusion The Canetti-Krawczyk proof model is very attractive due to its modular nature.  ...

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.  ...

Anonymous Network Information Acquirement Protocol for Mobile Users in Heterogeneous Wireless Networks

Guangsong Li, Qi Jiang, Yanan Shi, Fushan Wei
2016 International Journal of Network Security  
Media independent information service is one of the important parts of the IEEE 802.21 standard to optimize vertical handover in wireless heterogeneous networks.  ...  In this paper, an anonymous network information acquirement protocol is proposed for a mobile user, which can be used to establish a secure channel between the mobile user and the information server.  ...  Acknowledgments The authors would like to thank the anonymous reviewers and the editor for their comments that will help them to improve this paper.  ...

Okamoto-Tanaka Revisited: Fully Authenticated Diffie-Hellman with Minimal Overhead [chapter]

Rosario Gennaro, Hugo Krawczyk, Tal Rabin
2010 Lecture Notes in Computer Science  
Yet, after introducing some simple but crucial hashing operations, we obtain a protocol, mOT, for which we present a rigorous proof of security in the Canetti-Krawczyk (CK) Key-Agreement Protocol model  ...  For the proof of full PFS against active attackers (and only for this proof) we resort to non-black-box assumptions in the form of the "knowledge of exponent" assumptions.  ...  The views and conclusions contained in this document are those of the authors and should not be interpreted as representing the official policies, either expressed or implied, of the US Army Research Laboratory  ...

A Modular Security Analysis of the TLS Handshake Protocol [chapter]

P. Morrissey, N. P. Smart, B. Warinschi
2008 Lecture Notes in Computer Science  
The main contribution of the paper is a modular and generic proof of security for the application keys established through the TLS protocol.  ...  The security of the overall protocol then follows from proofs of security for the basic pre-master key generation protocols employed by TLS.  ...  Finally, an important security model that is related to ours is that of Canetti and Krawczyk (CK) [13] .  ...

Generic Forward-Secure Key Agreement Without Signatures [chapter]

Cyprien de Saint Guilhem, Nigel P. Smart, Bogdan Warinschi
2017 Lecture Notes in Computer Science  
We prove the security of our transformation in the random oracle model.  ...  An additional feature of our proposal is that it helps avoid the bad practice of using long term keys certified for encryption to produce digital signatures.  ...  The first generic compilers for authenticated key exchange were by Bellare, Canetti, and Krawczyk [3] later refined by Canetti and Krawczyk [9] .  ...

AuCPace: Efficient verifier-based PAKE protocol tailored for the IIoT

Björn Haase, Benoît Labrique
2019 Transactions on Cryptographic Hardware and Embedded Systems  
Specifically the use of a verifier-based password-authenticated key-exchange (V-PAKE) protocol as a hedge against public-key-infrastructure (PKI) failures is considered important.  ...  The differences between IIoT and the conventional Internet use-cases result in largely modified threats and require special procedures for allowing both, convenient and secure use in the highly constrained  ...  Acknowledgements The authors would like to thank the anonymous referees for their helpful comments and advice and their great care with the manuscript.  ...

Future-Proofing Key Exchange Protocols

Their model constitutes the basis of the many subsequent treatments of authenticated key exchange security, including the models presented in this thesis.  ...  key exchange protocol is only known to the participants in the protocol and can be used securely in cryptographic protocols, i.e., is sufficiently random.  ...  The results in this thesis focus on the case of mutually authenticated key exchange protocols between two parties with pre-specified peers as introduced by Canetti and Krawczyk [CK02] , i.e., the identity  ...
