Modern cryptographic algorithms play an irreplaceable role in data communication systems
for various areas of applications. These algorithms are the backbone of data protection and …

In the past few years, lightweight cryptography has become a popular research discipline
with a number of ciphers and hash functions proposed. The designers' focus has been …

In this paper, we propose a new lightweight block cipher named RECTANGLE. The main
idea of the design of RECTANGLE is to allow lightweight and fast implementations using bit …

This is the second edition of Understanding Cryptography. Ever since we released the first
edition in 2009, we have been humbled by the many positive responses we received from …

In this paper we propose a new family of very efficient hardware oriented block ciphers. The
family contains six block ciphers divided into two flavors. All block ciphers share the 80-bit …

Our contribution is twofold: first we describe a very compact hardware implementation of
AES-128, which requires only 2400 GE. This is to the best of our knowledge the smallest …

Resource-efficient cryptographic primitives are essential for realizing both security and
efficiency in embedded systems like RFID tags and sensor nodes. Among those primitives …

In this paper, we propose a new block cipher HIGHT with 64-bit block length and 128-bit key
length. It provides low-resource hardware implementation, which is proper to ubiquitous …

The Internet of Things, abbreviated as IoT, is a new networking paradigm composed of
wireless and wired networks, geographically distributed and interconnected by a “secured” …

The tight cost and implementation constraints of high-volume products, including secure
RFID tags and smart cards, require specialized cryptographic implementations. The authors …
