Improving Stateless Hash-Based Signatures

Jean-Philippe Aumasson

present several optimizations to SPHINCS, a stateless hash-based signature scheme proposed by Bernstein et al. in (2015): PORS, a more secure variant of the HORS few-time signature scheme used in SPHINCS; secret key caching, to speed-up signing and reduce ...

OmniLedger: A Secure, Scale-Out, Decentralized Ledger via Sharding

Bryan Alexander Ford, Linus Gasser, Eleftherios Kokoris Kogias, Philipp Svetolik Jovanovic, Nicolas Gailly

Designing a secure permissionless distributed ledger (blockchain) that performs on par with centralized payment processors, such as Visa, is a challenging task. Most existing distributed ledgers are unable to scale-out, i.e., to grow their total processing ...

Circular Security Reconsidered

Serge Vaudenay, Fatma Betül Durak

The notion of circular security of pseudorandom functions (PRF) was introduced in Distance Bounding Protocols. So far, only a construction based on a random oracle model was proposed. Circular security stands between two new notions which we call Key Depen ...

High System-Code Security with Low Overhead

George Candea, Johannes Kinder, Volodymyr Kuznetsov, Jonas Benedict Wagner

Security vulnerabilities plague modern systems because writing secure systems code is hard. Promising approaches can retrofit security automatically via runtime checks that implement the desired security policy; these checks guard critical operations, like ...

Making Masking Security Proofs Concrete - Or How to Evaluate the Security of any Leaking Device

Alexandre Raphaël Duc, Sebastian Faust

We investigate the relationships between theoretical studies of leaking cryptographic devices and concrete security evaluations with standard side-channel attacks. Our contributions are in four parts. First, we connect the formal analysis of the masking co ...

Online Authenticated-Encryption and its Nonce-Reuse Misuse-Resistance

Damian Vizár, Reza Reyhanitabar

A definition of online authenticated-encryption (OAE), call it OAE1, was given by Fleischmann, Forler, and Lucks (2012). It has become a popular definitional target because, despite allowing encryption to be online, security is supposed to be maintained ev ...

Optimal Proximity Proofs Revisited

Serge Vaudenay, Handan Kilinç Alper

Distance bounding protocols become important since wireless technologies become more and more common. Therefore, the security of the distance bounding protocol should be carefully analyzed. However, most of the protocols are not secure or their security is ...

Game Theory Meets Network Security and Privacy

Jean-Pierre Hubaux

This survey provides a structured and comprehensive overview of research on security and privacy in computer and communication networks that use game-theoretic approaches. We present a selected set of works to highlight the application of game theory in ad ...

Secure & Lightweight Distance-Bounding

Serge Vaudenay, Aikaterini Mitrokotsa

Distance-bounding is a practical solution to be used in security-sensitive contexts, mainly to prevent relay attacks. The main challenge when designing such protocols is maintaining their inexpensive cryptographic nature, whilst being able to protect again ...
