The need for lightweight cryptographic hash functions has been repeatedly expressed by
application designers, notably for implementing RFID protocols. However not many designs …

Formal RFID security and privacy frameworks are fundamental to the design and analysis of
robust RFID systems. In this paper, we develop a new definitional framework for RFID …

This paper describes and analyzes the security of a general-purpose cryptographic function
design, with application in RFID tags and sensor networks. Based on these analyzes, we …

We present the concept of greedy distinguishers and show how some simple observations
and the well known greedy heuristic can be combined into a very powerful strategy (the …

This paper presents the first results on AIDA/cube, algebraic and side-channel attacks on
variable number of rounds of all members of the KATAN family of block ciphers. Our cube …

The Fibonacci and the Galois configurations of nonlinear feedback shift registers (NLFSRs)
are considered. In the former, the feedback is applied to the input bit of the shift register only …

In this paper, a privacy preserving authentication protocol for RFID that relies on a single
cryptographic component, a lightweight stream cipher, is constructed. The goal is to provide …

A common approach to protect confidential information is to use a stream cipher which
combines plain text bits with a pseudo-random bit sequence. Among the existing stream …

This thesis is dedicated to symmetric cryptographic algorithms. The major focus of the work
is on block ciphers themselves as well as on hash functions and message authentication …

In this paper, we investigate the security of the NOEKEON block cipher against side channel
cube attacks. NOEKEON was proposed by Daemen et al. for the NESSIE project. The block …
