LBlock: a lightweight block cipher

by Wenling Wu, Lei Zhang - IN: APPLIED CRYPTOGRAPHY AND NETWORK SECURITY , 2011
"... In this paper, we propose a new lightweight block cipher called LBlock. Similar to many other lightweight block ciphers, the block size of LBlock is 64-bit and the key size is 80-bit. Our security evaluation shows that LBlock can achieve enough security margin against known attacks, such as differ ..."

Cryptanalysis of the Speck Family of Block Ciphers

by unknown authors , 2013
"... Abstract. Simon and Speck are two families of ultra-lightweight block ciphers which were announced by the U.S. National Security Agency in June 2013. This paper presents differential and rectangle attacks for almost all members of the Speck family of ciphers, where we target up to 11/22, 12/23, 15/2 ..."

The LED Block Cipher

by Jian Guo, Thomas Peyrin, Axel Poschmann, Matt Robshaw - Cryptographic Hardware and Embedded Systems - CHES 2011, volume 6917 of LNCS , 2011
"... Abstract. We present a new block cipher LED. While dedicated to compact hardware implementation, and offering the smallest silicon footprint among comparable block ciphers, the cipher has been designed to simultaneously tackle three additional goals. First, we explore the role of an ultra-light (in ..."

A Survey on Lightweight Block Ciphers

by Prabhat Kumar Kushwaha, M. P. Singh, Prabhat Kumar
"... Ubiquitous and pervasive computing are new era of computing and it needs lightweight cryptographic algorithms for security. Lightweight cryptography is used for resource constrained devices (which have limited memory, limited power and less processing capability) such as radio frequency identificati ..."

The design of lightweight block ci-pher has been active research topic over the years. The com-parative evaluations of these block ciphers (which actually reach low cost goal) on any

Analysis of Lightweight Stream Ciphers

by Simon Fischer - PHD THESIS , 2008
"... Stream ciphers are fast cryptographic primitives to provide confidentiality of electronically transmitted data. They can be very suitable in environments with restricted resources, such as mobile devices or embedded systems. Practical examples are cell phones, RFID transponders, smart cards or devic ..."

or devices in sensor networks. Besides efficiency, security is the most important property of a stream cipher. In this thesis, we address cryptanalysis of modern lightweight stream ciphers. We derive and improve cryptanalytic methods for different building blocks and present dedicated attacks on specific

A Family of Light-Weight Block Ciphers Based on DES Suited For RFID Applications

by Axel Poschmann, Gregor Leander, Kai Schramm, Christof Paar - PROCEEDINGS OF FSE 2007, LNCS , 2006
"... We propose a new block cipher, DESL (DES Lightweight extension), which is strong, compact and efficient. Due to its low chip size constraints DESL is especially suited for RFID (Radio Frequency Identification) devices. Our proposed DESL is based on the classical DES (Data Encryption Standard) des ..."

"... Abstract. In the last few years, the field of lightweight cryptography has seen an influx in the number of block ciphers and hash functions being proposed. One of the metrics that define a good lightweight design is the energy consumed per unit operation of the algorithm. For block ciphers, this ope ..."

Implementing Lightweight Block Ciphers on x86 Architectures

by Ryad Benadjila, Jian Guo, Victor Lomné, Thomas Peyrin
