Privacy Loss Classes: The Central Limit Theorem in Differential Privacy
differential privacy privacy loss
2018/11/19
In recent years, privacy enhancing technologies have gained tremendous momentum and they are expected to keep a sustained importance. Quantifying the degree of privacy offered by any mechanism working...
On the Security Loss of Unique Signatures
unique signatures security loss black-box impossibility
2018/11/9
We consider the question of whether the security of unique digital signature schemes can be based on game-based cryptographic assumptions using linear-preserving black-box security reductions—that is,...
Iterated Random Oracle: A Universal Approach for Finding Loss in Security Reduction
Random Oracle Indistinguishability Security under Computational Assumptions Finding Loss
2016/12/9
The indistinguishability security of a public-key cryptosystem can be reduced to a computational hard assumption in the random oracle model, where the solution to a computational hard problem is hidde...
Collision Spectrum, Entropy Loss, T-Sponges, and Cryptanalysis of GLUON-64
random function Collision Probability Spectrum collision tree
2016/1/23
In this paper, we investigate the properties of iterative non-injective functions and the security of primitives where they are used. First, we introduce the Collision Probability Spectrum (CPS) param...

Pairing-friendly elliptic curves with small security loss by Cheon’s algorithm
Pairing based cryptosystem Elliptic curves Weil pairing
2009/1/4
Pairing based cryptography is a new public key cryptographic
scheme. An elliptic curve suitable for pairing based cryptography is called
a “pairing-friendly” elliptic curve. After Mitsunari, Sakai a...
