In this article, we investigate the use of limited-birthday distinguishers to the context of hash
functions. We first provide a proper understanding of the limited-birthday problem and …

In this article, we propose an improved cryptanalysis of the double-branch hash function
standard RIPEMD-160. Using a carefully designed non-linear path search tool, we study the …

In this article we propose a new cryptanalysis method for double-branch hash functions that
we apply on the standard RIPEMD-128, greatly improving over know results. Namely, we …

This paper presents new attacks on message authentication codes (MACs). Our attacks are
generic and applicable to (secret-prefix) ChopMD-MAC and to NMAC/HMAC, all of which …

The continuous participation of citizens in the decisional processes of the community
through the submission of their opinions is a key factor of e-democracy. To do this, it appears …

This is the first research report with specific technical focus on cryptographic 'proof of work'in
the context of virtual crypto-currencies such as Bitcoin. Situated somewhere along the …

Das Buch bietet einen umfassenden Überblick über die Grundlagen moderner
kryptographischer Verfahren und ihre programmtechnische Entwicklung mit Hilfe einer …

Researchers have found many flaws in hash function such as MD5 algorithm. It has been
one of the most widely used hash algorithm and it has been indicated that there is a security …

Abstract We present an Intellectual Property (IP) protection technique for sequential circuits
driven by embedding a decomposed signature into a Finite State Machine (FSM) through …

The deployment of mobile ad‐hoc networks involves several configuration steps, which
complicate research efforts and hinder user interest. This problem prompts for new …
