$\textnormal{\textsc{TWINE}}$ : A Lightweight Block Cipher for Multiple Platforms

چکیده
This paper presents a 64-bit lightweight block cipher TWINE supporting 80 and 128bit keys. TWINE realizes quite small hardware implementation similar to the previous lightweight block cipher proposals, yet enables efficient software implementations on various platforms, from micro-controller to high-end CPU. This characteristic is obtained by the use of generalized Feistel structure combined with an improved block shuffle, introduced at FSE 2010.

متن کاملBiclique Cryptanalysis of TWINE
TWINE is a lightweight block cipher proposed at ECRYPT Workshop on Lightweight Cryptography 2011, Belgium. The cipher consists of 36 rounds and has two versions TWINE-80 and TWINE-128 supporting key lengths of 80 and 128 bits, respectively. The block length of the two versions is 64-bit. In this paper, we present the first single-key attacks on the both versions of the cipher. In these attacks,...
متن کاملBiclique Cryptanalysis of Block Ciphers LBlock and TWINE-80 with Practical Data Complexity
In the biclique attack, a shorter biclique usually results in less data complexity, but at the expense of more computational complexity. The early abort technique can be used in partial matching part of the biclique attack in order to slightly reduce the computations. In this paper, we make use of this technique, but instead of slight improvement in the computational complexity, we keep the amo...
متن کاملTriathlon of Lightweight Block Ciphers for the Internet of Things
In this paper we introduce an open framework for the benchmarking of lightweight block ciphers on a multitude of embedded platforms. Our framework is able to evaluate execution time, RAM footprint, as well as (binary) code size, and allows a user to define a custom “figure of merit” according to which all evaluated candidates can be ranked. We used the framework to benchmark various implementat...
متن کاملSoftware Implementation And Evaluation Of Lightweight Symmetric Block Ciphers Of The Energy Perspectives And Memory
Lightweight ciphers are the form of encryption that strictly limited to devices such as tags, RFID, wireless sensor networks applications. Low-resource devices has many limitations in power, energy and memory. In this work, the lightweight block ciphers is implemented on the Atmega128 microprocessor and the results of the energy perspectives and memory were assessed. The results of the evaluati...
