The Role of Compromised Accounts in Social Media Manipulation
In recent years we have seen a marked increase in disinformation including as part of a strategy of so-called hybrid warfare. Adversaries not only directly spread misleading content but manipulate social media by employing sophisticated techniques that exp ...
EPFL2022Experimental Investigation of Enhanced Grooves for Herringbone Grooved Journal Bearings
Jürg Alexander Schiffmann, Patrick Hubert Wagner, Philipp Kaspar Bättig
This paper presents the results of a theoretical and experimental investigation of the potential of enhanced groove geometries to increase the bearing clearance of a Herringbone Grooved Journal Bearing (HGJB) supported rotor. The theoretical study investig ...
2022Cryptanalysis of LowMC instances using single plaintext/ciphertext pair
Serge Vaudenay, Subhadeep Banik, Fatma Betül Durak, Khashayar Barooti
Arguably one of the main applications of the LowMC family ciphers is in the post-quantum signature scheme PICNIC. Although LowMC family ciphers have been studied from a cryptanalytic point of view before, none of these studies were directly concerned with ...
RUHR-UNIV BOCHUM, HORST GORTZ INST IT-SICHERHEIT2020Are Cloud FPGAs Really Vulnerable to Power Analysis Attacks?
Francesco Regazzoni, Mirjana Stojilovic, Louis Coulon, Ognjen Glamocanin
Recent works have demonstrated the possibility of extracting secrets from a cryptographic core running on an FPGA by means of remote power analysis attacks. To mount these attacks, an adversary implements a voltage fluctuation sensor in the FPGA logic, rec ...
2020Energy Analysis of Lightweight AEAD Circuits
Subhadeep Banik, Muhammed Fatih Balli
The selection criteria for NIST's Lightweight Crypto Standardization (LWC) have been slowly shifting towards the lightweight efficiency of designs, given that a large number of candidates already establish their security claims on conservative, well-studie ...
2020Automated Side-Channel Vulnerability Discovery and Hardening
In traditional cryptography, an attacker tries to infer a mathematical relationship between the inputs and outputs of a cryptosystem to recover secret information. With the advances in the theoretical basis of the cryptographic algorithms, this task became ...
EPFL2014Generalised Mersenne Numbers Revisited
Generalised Mersenne Numbers (GMNs) were defined by Solinas in 1999 and feature in the NIST (FIPS 186-2) and SECG standards for use in elliptic curve cryptography. Their form is such that modular reduction is extremely efficient, thus making them an attrac ...
2013An Architecture-Independent Instruction Shuffler to Protect against Side-Channel Attacks
Paolo Ienne, Ali Galip Bayrak, Wayne Burleson, Nikola Velickovic
Embedded cryptographic systems, such as smart cards, require secure implementations that are robust to a variety of low-level attacks. Side-Channel Attacks (SCA) exploit the information such as power consumption, electromagnetic radiation and acoustic leak ...
2012Resistance against Adaptive Plaintext-Ciphertext Iterated Distinguishers
Serge Vaudenay, Atefeh Mashatan, Asli Bay
Decorrelation Theory deals with general adversaries who are mounting iterated attacks, i.e., attacks in which an adversary is allowed to make d queries in each iteration with the aim of distinguishing a random cipher C from the ideal random cipher C^*. A b ...
