The RC5 Encryption Algorithm

by Ronald L. Rivest , 1995
"... Abstract. This document describes the RC5 encryption algorithm. RC5 is a fast symmetric block cipher suitable for hardware or software implementations. A novel feature of RC5 is the heavy use of data-dependent rotations. RC5 has a variable word size, a variable number of rounds, and a variable-lengt ..."

A Concrete Security Treatment of Symmetric Encryption

by M. Bellare, A. Desai, E. Jokipii, P. Rogaway - Proceedings of the 38th Symposium on Foundations of Computer Science, IEEE , 1997
"... We study notions and schemes for symmetric (ie. private key) encryption in a concrete security framework. We give four di erent notions of security against chosen plaintext attack and analyze the concrete complexity ofreductions among them, providing both upper and lower bounds, and obtaining tight ..."

Next we provide concrete security analyses of methods to encrypt using a block cipher, including the most popular encryption method, CBC. We establish tight

PRESENT: An Ultra-Lightweight Block Cipher

by A. Bogdanov, L. R. Knudsen, G. Leander, C. Paar, A. Poschmann, M. J. B. Robshaw, Y. Seurin, C. Vikkelsoe - THE PROCEEDINGS OF CHES 2007 , 2007
"... With the establishment of the AES the need for new block ciphers has been greatly diminished; for almost all block cipher applications the AES is an excellent and preferred choice. However, despite recent implementation advances, the AES is not suitable for extremely constrained environments such ..."

The block cipher SC2000

by Takeshi Shimoyama, Hitoshi Yanami, Kazuhiro Yokoyama, Masahiko Takenaka, Kouichi Itoh, Jun Yajima, Naoya Torii - In Preproceedings of FSE 2001 , 2001
"... Abstract. In this paper, we propose a new symmetric key block cipher SC2000 with 128-bit block length and 128-,192-,256-bit key lengths. The block cipher is constructed by piling two layers: one is a Feistel structure layer and the other is an SPN structure layer. Each operation used in two layers i ..."

On the Cryptographic Strength of Symmetric Ciphers Suitable for Power-Line Communications Abstract

by Reiner Dojen, Tom Coffey
"... Power-line communications (PLC) use publicly accessible power-lines for the transmission of data. The powerline should be viewed as a hostile channel requiring special security services, if secure communication is desired. This paper introduces cryptography and related services. The operation and ch ..."

and characteristics of some symmetric block ciphers for PLC use are reviewed. These characteristics include security, speed and flexibility. Exhaustive key search is suggested as a first yardstick for the security of ciphers and a minimal key length to provide adequate security is proposed. Differential and linear

Cipher

by A. Alkalbany, H. Al Hassan, M. Saeb
"... Abstract---The “PYRAMIDS ” Block Cipher is a symmetric encryption algorithm of a 64, 128, 256-bit length, that accepts a variable key length of 128, 192, 256 bits. The algorithm is an iterated cipher consisting of repeated applications of a simple round transformation with different operations and d ..."
