On the Data Limitation of Small-State Stream Ciphers: Correlation Attacks on Fruit-80 and Plantlet
Small-state stream cipher Grain Correlation attack
font style='font-size:12px;'>
2019/7/15
Many cryptographers have focused on lightweight cryptography, and a huge number of lightweight block ciphers have been proposed. On the other hand, designing lightweight stream ciphers is a challengin...
Fast Correlation Attacks on Grain-like Small State Stream Ciphers and Cryptanalysis of Plantlet, Fruit-v2 and Fruit-80
Fast correlation attack Stream cipher Grain-like
font style='font-size:12px;'>
2019/7/8
The fast correlation attack (FCA) is one of the most important cryptanalytic techniques against LFSR-based stream ciphers. In CRYPTO 2018, Todo et al. found a new property for the FCA and proposed a n...
Efficient Pseudorandom Correlation Generators: Silent OT Extension and More
Secure computation correlated randomness pseudorandom correlation generator

2019/5/9
Secure multiparty computation (MPC) often relies on sources of correlated randomness for better efficiency and simplicity. This is particularly useful for MPC with no honest majority, where input-inde...
Horizontal Collision Correlation Attack on Elliptic Curves

2019/4/1
Elliptic curves based algorithms are nowadays widely spread among embedded systems. They indeed have the double advantage of providing efficient implementations with short certi cates and of being rel...
Security Evaluation for Snow 2.0-like Stream Ciphers Against Correlation Attacks over Extension Fields
symmetric cryptography stream cipher correlation attack
font style='font-size:12px;'>
2019/3/20
We propose a general method for security evaluation of SNOW 2.0-like ciphers against correlation attacks that are built similarly to known attacks on SNOW 2.0. Unlike previously known methods, the met...
Correlation of Quadratic Boolean Functions: Cryptanalysis of All Versions of Full MORUS
Quadratic Boolean function Disjoint quadratic form Correlation attack
font style='font-size:12px;'>
2019/3/1
We show that the correlation of any quadratic Boolean function can be read out from its so-called disjoint quadratic form. We further propose a polynomial-time algorithm that can transform an arbitrar...
Zero-Correlation Attacks on Tweakable Block Ciphers with Linear Tweakey Expansion
Symmetric-key cryptography tweakable block ciphers zero-correlation
font style='font-size:12px;'>
2019/3/1
The design and analysis of dedicated tweakable block ciphers is a quite recent and very active research field that provides an ongoing stream of new insights. For instance, results of Kranz, Leander, ...
Non-Interactive Zero Knowledge and Correlation Intractability from Circular-Secure FHE
NIZK LWE
font style='font-size:12px;'>
2019/1/4
We construct non-interactive zero-knowledge (NIZK) arguments for NPNP from any circular-secure fully homomorphic encryption (FHE) scheme. In particular, we obtain such NIZKs under a circular-secure va...
Block Cipher Invariants as Eigenvectors of Correlation Matrices
invariant subspace attack nonlinear invariant attack linear cryptanalysis
font style='font-size:12px;'>
2018/8/21
A new approach to invariant subspaces and nonlinear invariants is developed. This results in both theoretical insights and practical attacks on block ciphers. It is shown that, with minor modification...
Fast Correlation Attack Revisited --Cryptanalysis on Full Grain-128a, Grain-128, and Grain-v1
Fast correlation attack Stream cipher LFSR
font style='font-size:12px;'>
2018/6/5
A fast correlation attack (FCA) is a well-known cryptanalysis technique for LFSR-based stream ciphers. The correlation between the initial state of an LFSR and corresponding key stream is exploited, a...
Sliding-Window Correlation Attacks Against Encryption Devices with an Unstable Clock
Power analysis SW-CPA Jittered clocks
font style='font-size:12px;'>
2018/4/9
Power analysis side channel attacks rely on aligned traces. As a counter-measure, devices can use a jittered clock to misalign the power traces. In this paper we suggest a way to overcome this counter...
Hadamard Matrices, d-Linearly Independent Sets and Correlation-Immune Boolean Functions with Minimum Hamming Weights
Boolean functions Correlation-immune Minimum-weight
font style='font-size:12px;'>
2018/3/26
It is known that correlation-immune (CI) Boolean functions used in the framework of side channel attacks need to have low Hamming weights. In 2013, Bhasin et al. studied the minimum Hamming weight of ...
Correlation Cube Attacks: From Weak-Key Distinguisher to Key Recovery

2018/3/7
In this paper, we describe a new variant of cube attacks called correlation cube attack. The new attack recovers the secret key of a cryptosystem by exploiting conditional correlation properties betwe...
