Authenticated ID-based Key Exchange and remote log-in with simple token and PIN number
Authenticated key exchange protocols tend to be either token based or password based. Token based schemes are often based on expensive (and irreplaceable) smart-card tokens, while password-only schemes require that a unique password is shared between every pair of correspondents. The magnetic strip swipe card and associated PIN number is a familiar and convenient format that motivates a combine...
متن کاملAttack on An ID-based Authenticated Group Key Exchange Protocol with Identifying Malicious Participants
An authenticated group key exchange (AGKE) protocol allows a group of participants to establish a common session key and then provides secure group communications in collaborative and distributed applications. Recently, Wu et al. proposed an ID-based authenticated group key exchange protocol based on bilinear pairings. They claimed that their protocol can detect and identify the malicious parti...
متن کاملSecure Communications over Insecure Channels Based on Short Authenticated Strings
We propose a way to establish peer-to-peer authenticated communications over an insecure channel by using an extra channel which can authenticate very short strings, e.g. 15 bits. We call this SAS-based authentication as for authentication based on Short Authenticated Strings. The extra channel uses a weak notion of authentication in which strings cannot be forged nor modified, but whose delive...
متن کاملCryptanalysis of ID-based Tripartite Authenticated Key Agreement Protocols
In this paper, we show that the Nalla-Reddy’s one round IDbased tripartite authenticated key agreement protocols are still insecure against the man-in-the-middle attacks. We also break the Nalla’s IDbased tripartite authenticated key agreement protocol with signatures.
متن کاملA New Ring-Based SPHF and PAKE Protocol On Ideal Lattices
emph{ Smooth Projective Hash Functions } ( SPHFs ) as a specific pattern of zero knowledge proof system are fundamental tools to build many efficient cryptographic schemes and protocols. As an application of SPHFs, emph { Password - Based Authenticated Key Exchange } ( PAKE ) protocol is well-studied area in the last few years. In 2009, Katz and Vaikuntanathan described the first lattice-based ...
