Evaluation and optimization of renewable energy in the Quartier Nord: objective zero-power

Jean-Louis Scartezzini, Jérôme Henri Kämpf, Dasaraden Mauree, Yang Yao

Buildings account for almost 40% of energy consumption in European countries and hence are responsible for a significant part of greenhouse gas emissions. Recent regulations and standards (Minergie, Minergie P, etc.) are strongly encouraging more sustainab ...

Efficient Recursive Diffusion Layers for Block Ciphers, and Hash Functions

Pouyan Sepehrdad

Many modern block ciphers use maximum distance separable (MDS) matrices as the main part of their diffusion layers. In this paper, we propose a very efficient new class of diffusion layers constructed from several rounds of Feistel-like structures whose ro ...

Boosting OMD for Almost Free Authentication of Associated Data

Serge Vaudenay, Damian Vizár, Reza Reyhanitabar

We propose pure OMD (p-OMD) as a new variant of the Offset Merkle-Damgård (OMD) authenticated encryption scheme. Our new scheme inherits all desirable security features of OMD while having a more compact structure and providing higher efficiency. The origi ...

Revisiting Iterated Attacks in the Context of Decorrelation Theory

Serge Vaudenay, Atefeh Mashatan, Asli Bay

Iterated attacks are comprised of iterating adversaries who can make d plaintext queries, in each iteration to compute a bit, and are trying to distinguish between a random cipher C and the perfect cipher C* based on all bits. Vaudenay showed that a 2d-dec ...

Breaking the IOC Authenticated Encryption Mode

Serge Vaudenay, Reza Reyhanitabar, Paul Bottinelli

In this paper we cryptanalyse a block cipher mode of operation, called Input Output Chaining (IOC), designed by Recacha and submitted to NIST in 2013 for consideration as a lightweight authenticated encryption mode. We present an existential forgery attack ...

MEU: An urban energy management tool for communities and multi-energy utilities

François Maréchal, Gaëtan Cherix, Massimiliano Capezzali, Jakob Moritz Fabian Rager, Damien Rebeix

In order to facilitate urban energy management and energy planning, the project MEU developed a web based tool as a decision support system for decision makers. Using a web based approach minimizes the effort on the client site as no software needs to be i ...

Statistical and Algebraic Cryptanalysis of Lightweight and Ultra-Lightweight Symmetric Primitives

Pouyan Sepehrdad

Symmetric cryptographic primitives such as block and stream ciphers are the building blocks in many cryptographic protocols. Having such blocks which provide provable security against various types of attacks is often hard. On the other hand, if possible, ...
