Some Cryptanalytic Results on Lizard

Subhadeep Banik

Lizard is a lightweight stream cipher proposed by Hamann, Krause and Meier in IACR ToSC 2017. It has a Grain-like structure with two state registers of size 90 and 31 bits. The cipher uses a 120 bit secret key and a 64 bit IV. The authors claim that Lizard ...

Side-Channel Attacks on Threshold Implementations using a Glitch Algebra

Serge Vaudenay

Threshold implementations allow to implement circuits us- ing secret sharing in a way to thwart side-channel attacks based on prob- ing or power analysis. It was proven they resist to attacks based on glitches as well. In this report, we show the limitatio ...

Considerations for Rank-based Cryptosystems

Anna-Lena Horlemann, Joachim Rosenthal

Cryptosystems based on rank metric codes have been considered as an alternative to McEliece cryptosystems due to the relative difficulty of solving the rank syndrome decoding problem. Generic attacks have recently seen several improvements, notably in the ...

Distance Bounding based on PUF

Serge Vaudenay, Mathilde Igier

Distance Bounding (DB) is designed to mitigate relay attacks. This paper provides a complete study of the DB protocol of Kleber et al. based on Physical Unclonable Functions (PUFs). We contradict the claim that it resists to Terrorist Fraud (TF). We propos ...

Practical and Provably Secure Distance-Bounding

Serge Vaudenay, Aikaterini Mitrokotsa

From contactless payments to remote car unlocking, many applications are vulnerable to relay attacks. Distance bounding protocols are the main practical countermeasure against these attacks. In this paper, we present a formal analysis of SKI, which recentl ...

Tornado Attack on RC4 with Applications to WEP & WPA

Serge Vaudenay, Martin Vuagnoux, Pouyan Sepehrdad, Petr Susil

In this paper, we construct several tools for building and manipulating pools of biases in the analysis of RC4. We report extremely fast and optimized active and passive attacks against IEEE 802.11 wireless communication protocol WEP and a key recovery and ...

The Limits of Composable Crypto with Transferable Setup Devices

Serge Vaudenay, Miyako Ohkubo

UC security realized with setup devices imposes that single instances of these setups are used. In most cases, UC-realization relies further on other properties of the setups devices, like tamper-resistance. But what happens in stronger versions of the UC ...

Mitigating Crime Risks in the International Logistics Network

Toni Antero Männistö

The terrorist attacks of September 11, 2001 raised major concerns about the vulnerability of global transportation systems to transnational crime and terrorism. Although the attacks occurred in the context of passenger transport, they spurred unprecedented ...

Motion-Based Counter-Measures to Photo Attacks in Face Recognition

Sébastien Marcel, André Anjos, Murali Mohan Chakka

Identity spoofing is a contender for high-security face recognition applications. With the advent of social media and globalized search, our face images and videos are wide-spread on the internet and can be potentially used to attack biometric systems with ...

On the Need for Secure Distance-Bounding

Serge Vaudenay, Aikaterini Mitrokotsa

Distance-bounding is a practical solution to prevent relay attacks. Yet, security models are not well-established. We will briefly show recent techniques that expose serious distance-frauds, mafia-frauds, and/or terrorist-frauds on distance-bounding protoc ...
