PRESENT: An Ultra-Lightweight Block Cipher
Andrey Bogdanov,Lars R. Knudsen,Gregor Leander,Christof Paar,Axel Poschmann,Matthew Robshaw,Yannick Seurin,C. Vikkelsoe +7 more
TL;DR: An ultra-lightweight block cipher, present, which is competitive with today's leading compact stream ciphers and suitable for extremely constrained environments such as RFID tags and sensor networks.

PRESENT: An Ultra-Lightweight Block Cipher
Andrey Bogdanov,Lars R. Knudsen,Gregor Leander,Christof Paar,Axel Poschmann,Matthew Robshaw,Yannick Seurin,C. Vikkelsoe +7 more
TL;DR: In this paper, the authors describe an ultra-lightweight block cipher, present, which is suitable for extremely constrained environments such as RFID tags and sensor networks, but it is not suitable for very large networks such as sensor networks.
Book ChapterDOI
PRINCE: a low-latency block cipher for pervasive computing applications
Julia Borghoff,Anne Canteaut,Tim Güneysu,Elif Bilge Kavun,Miroslav Knezevic,Lars R. Knudsen,Gregor Leander,Ventzislav Nikov,Christof Paar,Christian Rechberger,Peter Maria Franciscus Rombouts,Søren S. Thomsen,Tolga Yalcin +12 more
TL;DR: In this paper, a block cipher called PRINCE is proposed that allows encryption of data within one clock cycle with a very competitive chip area compared to known solutions. But it does not have the α-reflection property, which holds that decryption for one key corresponds to encryption with another key.
Book ChapterDOI
The SKINNY Family of Block Ciphers and Its Low-Latency Variant MANTIS
Christof Beierle,Jérémy Jean,Stefan Kölbl,Gregor Leander,Amir Moradi,Thomas Peyrin,Yu Sasaki,Pascal Sasdrich,Siang Meng Sim +8 more
TL;DR: A new tweakable block cipher family SKINNY is presented, whose goal is to compete with NSA recent design SIMON in terms of hardware/software performances, while proving in addition much stronger security guarantees with regards to differential/linear attacks.

PRINCE – A Low-latency Block Cipher for Pervasive Computing Applications
Julia Borghoff,Anne Canteaut,Tim Güneysu,Elif Bilge Kavun,Miroslav Knežević,Lars R. Knudsen,Gregor Leander,Ventzislav Nikov,Christof Paar,Christian Rechberger,Peter Maria Franciscus Rombouts,Søren S. Thomsen,Tolga Yalcin +12 more
TL;DR: This paper presents a block cipher that is optimized with respect to latency when implemented in hardware and holds that decryption for one key corresponds to encryption with a related key, which is of independent interest and proves its soundness against generic attacks.
