Six shades lighter: a bit-serial implementation of the AES family

Subhadeep Banik, Muhammed Fatih Balli, Sergio Roldán Lombardía

Recently, cryptographic literature has seen new block cipher designs such as PRESENT, GIFT or SKINNY that aim to be more lightweight than the current standard, i.e., AES. Even though AES family of block ciphers were designed two decades ago, they still rem ...

The Area-Latency Symbiosis: Towards Improved Serial Encryption Circuits

Andrea Felice Caforio, Subhadeep Banik, Muhammed Fatih Balli

The bit-sliding paper of Jean et al. (CHES 2017) showed that the smallest-size circuit for SPN based block ciphers such as AES, SKINNY and PRESENT can be achieved via bit-serial implementations. Their technique decreases the bit size of the datapath and na ...

On Design of Robust Lightweight Stream Cipher with Short Internal State

Subhadeep Banik

The stream cipher Sprout with a short internal state was proposed in FSE 2015. Although the construction guaranteed resistance to generic Time Memory Data Tradeoff attacks, there were some weaknesses in the design and the cipher was completely broken. In t ...

Breaking The FF3 Format-Preserving Encryption Standard Over Small Domains

Serge Vaudenay, Fatma Betül Durak

The National Institute of Standards and Technology (NIST) recently published a Format-Preserving Encryption standard accepting two Feistel structure based schemes called FF1 and FF3. Particularly, FF3 is a tweakable block cipher based on an 8-round Feistel ...

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 ...

Structured Sparsity Models for Compressively Sensed Electrocardiogram Signals: A Comparative Study

David Atienza Alonso, Pierre Vandergheynst, Nadia Khaled, Hossein Mamaghanian

We have recently quantified and validated the potential of the emerging compressed sensing (CS) paradigm for real-time energy-efficient electrocardiogram (ECG) compression on resource-constrained sensors. In the present work, we investigate applying sparsi ...

ARMADILLO: A Multi-purpose Cryptographic Primitive Dedicated to Hardware

Serge Vaudenay, Stéphane Badel, Pouyan Sepehrdad, Nilay Dagtekin, Khaled Ouafi, Jorge Nakahara, Petr Susil

This paper describes and analyzes the security of a general-purpose cryptographic function design, with application in RFID tags and sensor networks. Based on these analyzes, we suggest minimum parameter values for the main components of this cryptographic ...

Linear (Hull) and Algebraic Cryptanalysis of the Block Cipher PRESENT

Pouyan Sepehrdad, Jorge Nakahara

The contributions of this paper include the first linear hull and a revisit of the algebraic cryptanalysis of reduced-round variants of the block cipher PRESENT, under known-plaintext and ciphertext- only settings. We introduce a pure algebraic cryptanalys ...
