Second International Workshop on Lightweight 

Cryptography for Security & Privacy 

(LightSec 2013) 

 May 6-7, 2013

Gebze, Turkey

The post-proceedings of the papers presented at the workshop has been published in Springer's LNCS Series. To have an access to the proceedings, click on  the book cover below:



Concept and Topics: LightSec is a crypto workshop aiming at promoting and initiating novel research on the security & privacy issues for applications that can be termed as lightweight security, due to the associated constraints on metrics such as available power, energy, computing ability, area, execution time, and memory requirements. As such applications are becoming ubiquitous, definitely providing an immense value to the society, they are also affecting a greater portion of the public & leading to a plethora of economical & security and privacy related concerns. The goal of this workshop is to create a platform where these concerns can be addressed and proposed solutions are discussed and evaluated.

Venue and Accommodation: LightSec 2013 is going to be held in TÜSSİDE Gebze, Turkey. The main hubs are Ataturk Airport and Sabiha Gökçen Airport. We will provide shuttle services from central points of Istanbul to arrive at TÜSSİDEFor the detailed information, please check the travel information page. All the participants paying the workshop registration fee will be provided accommodation and meals in TÜSSİDE. Please visit the registration page to register the workshop.

Registration Deadline: Tuesday, April 30th, 2013

Program: For the accepted papers and the program of the workshop, you can visit the accepted papers and program page. The proceedings of LightSec 2013 will be published as LNCS series of Springer Verlag. We have three invited speakers.  


Invited Speakers: 



Gregor Leander


Title: Design Strategies for Lightweight Block Ciphers: PRINCE and Beyond


Abstract: In this talk I will start by motivating that it is of importance to
broaden the scope of lightweight ciphers to include other criteria apart
from chip-size. After that I will in detail discuss the design of PRINCE
and outline how to approach the task of designing a lightweight block
cipher in general.


Short Bio: Gregor Leander is currently working at Ruhr University Bochum, Germany.He received his PhD in mathematics in 2004 and was an associate professor at the Technical University Denmark until 2012. His research interests include design and analysis of symmetric cryptography and Boolean functions. Recently he focused on lightweight cryptography and fundamental questions of block cipher design and analysis.





Axel Poschmann


Title: Implementation Aspects of Lightweight Cryptography


 Abstract: This talk focuses on implementation aspects of lightweight cryptography, in particular on Gate Equivalents. In the first part, the evolution of lightweight cryptography is reviewed and a few algorithms are compared regarding their design strategy and implementation results. In the second part side-channel aspects of lightweight cryptography are discussed. We focus on the Threshold Implementation and recent optimizations, which allow to reduce the area overhead even further.


Short Bio: Assistant Professor Axel York Poschmann is heading the Physical Analysis and Cryptographic Engineering laboratories at Nanyang Technological University. Axel holds a PhD degree (Dr.-Ing.) in EE and a Master degree (Dipl.-Ing.) in IT Security as well as a Master degree in Business Administration (Dipl.-Kfm.). He has published more than 30 papers in applied cryptography, and is a program committee member of several workshops. Being co-convenor of the cryptography working group of the IT Standards Committee in Singapore, he is also actively contributing to the ISO standardization process. He is also one of the lead designers of PRESENT, a standardized block cipher for lightweight cryptography (ISO/IEC 29192-2:2012), and he is recipient of the "IT-Sicherheitspreis 2010", one of Germany's highest R&D awards.





Jacques Stern 




 Title: Randomness and lack of randomness in cryptography.


Abstract: Since the early days of cryptography, randomness has been intimately tied with cryptography. After a brief historical introduction, the talk will provide examples of the interplay between randomness and cryptography, both with a theoretical and practical perspective. While the public key cryptography mostly illustrates the role of randomness and cryptanalysis of symmetric key systems usually relies on lack of randomness, recent examples may blur this vision. 


Short Bio: Jaccques Stern is a professor at the Ecole Normale Supérieure (ENS) in France. He is an expert in cryptography and has made over 100 contributions to scientific journals. His main work has been devoted to the cryptanalysis and provable security of public key algorithms, as well as to the design of cryptographic algorithms suitable for smart cards applications.Jacques Stern is a Fellow of the International Association for Cryptologic Research. He was also the recipient of the Lazare Carnot Prize from the French Academy of Sciences in 2003, of the CNRS Gold Medal, the highest French National Scientific Award in 2006, and of the RSA Award in 2007. From 2007 to 2010, Jacques Stern has been Chairman of the Board of the Agence Nationale de la Recherche (ANR), as well as Chairman of the Board of the company Ingenico, world supplier of transaction and secure payment solutions. Early in 2010, he has joined the French ministry of higher education and research as a senior advisor to the minister. In 2012, Jacques Stern has been appointed a member of the French National Regulatory Authority for Telecoms, and has resumed his teaching and research activities at ENS.
