A new hash function HeW: A hash function based on light weight block cipher FeW is proposed in this paper. The compression function of HeW is based on block cipher FeW. It is believed that key expansion algorithm of block cipher slows down the performance of the overlying hash function. Thereby, block ciphers become a less favourable choice to design a compression function. As a countermeasure,...

In this paper, we present a general framework for the automated design of cryptographic block ciphers by using Genetic Programming. We evolve highly nonlinear and extremely efficient functions that can be used as core components of any cryptographic construction. As an example, a new block cipher named Raiden is proposed. We present a preliminary security analysis of our proposal and a comparis...

Lightweight cryptographic primitives are essential for securing pervasive embedded devices like RFID tags, smart cards, and wireless sensor nodes. In this paper, we present a lightweight stream cipher WG-8, which is tailored from the well-known Welch-Gong (WG) stream cipher family, for resource-constrained devices. WG-8 inherits the good randomness and cryptographic properties of the WG stream ...

This paper introduces an area-optimized and power-efficient implementation of the Cipher Block Chaining (CBC) mode for ultra-lightweight block cipher, PRESENT, Keyed-Hash Message Authentication Code (HMAC)-expanded PHOTON by using a feedback path single in scheme. The proposed scheme is designed, taped out, integrated as System-on-a-Chip (SoC) 65-nm CMOS process. An experimental analysis compar...

Biclique attack, is a new cryptanalytic technique which brings new tools from the area of hash functions to the area of block cipher cryptanalysis. Till now, this technique is the only one able to analyze the full-round AES cipher in a single key scenario. In this paper, we introduce non-isomorphic biclique attack, a modified version of the original biclique attack. In this attack we obtain iso...

In this article, we analyse the known-key security of the standardized PRESENT lightweight block cipher. Namely, we propose a knownkey distinguisher on the full PRESENT, both 80and 128-bit key versions. We first leverage the very latest advances in differential cryptanalysis on PRESENT, which are as strong as the best linear cryptanalysis in terms of number of attacked rounds. Differential prop...

Two lightweight block cipher families, Simon and Speck, have been proposed by researchers from the NSA recently. In this paper, we introduce Simeck, a new family of lightweight block ciphers that combines the good design components from both Simon and Speck, in order to devise even more compact and e cient block ciphers. For Simeck32/64, we can achieve 505 GEs (before the Place and Route phase)...

The design and analysis of lightweight block ciphers has been a very active research area over the last couple of years, with many innovative proposals trying to optimize different performance figures. However, since these block ciphers are dedicated to low-cost embedded devices, their implementation is also a typical target for side-channel adversaries. As preventing such attacks with counterm...
