Improved Strongly Deniable Authenticated Key Exchanges for Secure Messaging
A deniable authenticated key exchange (DAKE) protocol establishes a secure channel without producing cryptographic evidence of communication. A DAKE offers strong deniability if transcripts provide no evidence even if long-term key material is compromised (offline deniability) and no outsider can obtain evidence even when interactively colluding with an insider (online deniability). Unfortunate...
متن کاملDeniable Authenticated Key Establishment for Internet Protocols
We propose two public-key schemes to achieve “deniable authentication” for the Internet Key Exchange (IKE). Our protocols can be implemented using different concrete mechanisms and we discuss different options; in particular we suggest solutions based on elliptic curve pairings. The protocol designs use the modular construction method of Canetti and Krawczyk which provides the basis for a proof...
متن کاملChameleon-Based Deniable Authenticated Key Agreement Protocol
As a useful means of safeguarding privacy of communications, deniable authentication has received much attention. A Chameleon-based deniable authenticated key agreement protocol is presented in this paper. The protocol has following properties. Any one of the two participants can’t present a digital proof to convince a third party that a claimed agreement has really taken place. Once a forgery ...
متن کاملAuthentication and Authenticated Key Exchanges
We discuss two-party mutual authentication protocols providing authenticated key exchange, focusing on those using asymmetric techniques. A simple, efficient protocol referred to as the station-to-station (STS) protocol is introduced, examined in detail, and considered in relation to existing protocols. The definition of a secure protocol is considered, and desirable characteristics of secure p...
متن کاملStrongly secure authenticated key exchange in the standard model
Nowadays many crucial network applications rely on the existence of a confidential channel established by authenticated key exchange (AKE) protocols over public networks. With the rapid development of cyber technology, novel attacks to cryptosystem emerge in an endless stream. This has also led to the development of AKE solutions to provide increasingly stronger security guarantees. In this the...
