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
Understanding Cryptography: A Textbook For Students And Practitioners
Christof Paar,Jan Pelzl +1 more
TL;DR: The authors move quickly from explaining the foundations to describing practical implementations, including recent topics such as lightweight ciphers for RFIDs and mobile devices, and current key-length recommendations.
BookDOI
Cryptographic Hardware and Embedded Systems - CHES 2002
TL;DR: A technology to block a new class of attacks on secure microcontrollers and smartcards whereby a logical 1 or 0 is not encoded by a high or low voltage on a single line, but by (HL or (LH) on a pair of lines.
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.
