Side-channel analysis of isogeny-based key encapsulation mechanisms and hash-based digital signatures
Current cryptographic solutions will become obsolete with the arrival of large-scale universal quantum computers. As a result, the National Institute of Standards and Technology supervises a post-quantum standardization process which involves evaluating ca ...
EPFL2024Analyzing and Protecting Communication Metadata
Most communication systems (e.g., e-mails, instant messengers, VPNs) use encryption to prevent third parties from learning sensitive information.However, encrypted communications protect the contents but often leak metadata: the amount of data sent and the ...
EPFL2021Misuse Attacks on Post-quantum Cryptosystems
Serge Vaudenay, Loïs Evan Huguenin-Dumittan, Abdullah Talayhan, Fatma Betül Durak, Ciprian Baetu
Many post-quantum cryptosystems which have been proposed in the National Institute of Standards and Technology (NISI) standardization process follow the same meta-algorithm, but in different algebras or different encoding methods. They usually propose two ...
SPRINGER INTERNATIONAL PUBLISHING AG2019Signature Schemes Secure Against Hard-to-Invert Leakage
Side-channel attacks allow the adversary to gain partial knowledge of the secret key when cryptographic protocols are implemented in real-world hardware. The goal of leakage resilient cryptography is to design cryptosystems that withstand such attacks. In ...
Springer2016Revisiting the Sanders-Bogolyubov-Ruzsa Theorem in F-p(n) and its Application to Non-malleable Codes
Non-malleable codes (NMCs) protect sensitive data against degrees of corruption that prohibit error detection, ensuring instead that a corrupted codeword decodes correctly or to something that bears little relation to the original message. The split-state ...
Ieee2016A Lightweight Cryptographic System for Implantable Biosensors
Giovanni De Micheli, Sandro Carrara, Seyedeh Sara Ghoreishizadeh, Wayne Burleson, Tolga Yalçin
This paper presents a lightweight cryptographic system integrated onto a multi-function implantable biosensor prototype. The resulting heterogeneous system provides a unique and fundamental capability by immediately encrypting and signing the sensor data u ...
2014TCHo: A Code-Based Cryptosystem
Serge Vaudenay, Alexandre Raphaël Duc
TCHo is a public-key cryptosystem based on the hardness of finding a multiple polynomial with low weight and on the hardness of distinguishing between the output of an LFSR with noise and some random source. An early version was proposed in 2006 by Finiasz ...
