Privacy Amplification with Asymptotically Optimal Entropy Loss
We study the problem of "privacy amplification": key agreement between two parties who both know a weak secret w, such as a password. (Such a setting is ubiquitous on th...

On Bluetooth Repairing: Key Agreement Based on Symmetric-Key Cryptography
Abstract. Despite many good (secure) key agreement protocols based on publickey cryptography exist, secure associations between two wireless devices are often established using sym...

An Authenticated Key Agreement Protocol Using Conjugacy Problem in Braid Groups
In this paper we propose an authenticated key agreement, which works in a braid group. We prove that our protocol meet the security attributes under the assumption that the Conjug...

A new framework for efficient password-based authenticated key exchange
Protocols for password-based authenticated key exchange (PAKE) allow two users who share only a short, low-entropy password to agree on a cryptographically strong session key. The...

Security Analysis of Standard Authentication and Key Agreement Protocols Utilising Timestamps
We propose a generic modelling technique that can be used to extend existing frameworks for theoretical security analysis in order to capture the use of timestamps. We apply this t...
