We show that Legendre PRF, recently suggested as an MPC-friendly primitive in a prime field ZpZp, admits key recovery attacks of complexity O(p√)O(p) rather than previously assumed O(p)O(p). We also d...
Practical Key-recovery Attacks on Round-Reduced Ketje Jr, Xoodoo-AE and Xoodyak
Conditional Cube Attack Keccak Ketje Jr
2019/5/9
Conditional cube attack was proposed by Huang et al. at EUROCRYPT 2017 to attack Keccak keyed mode. Inspired by dynamic cube attack, they reduce the degree by appending key bit conditions on the initi...

Deep Neural Networks (DNNs) have recently received significant attention in the side-channel community due to their state-of-the-art performance in security testing of embedded systems. However, resea...
A Refinement of “A Key-recovery Attack on 855-round Trivium" From CRYPTO 2018
Trivium Nullification Technique Polynomial Reduction
2018/11/5
At CRYPTO 2018, we proposed a method to reduce the Boolean polynomial of 855-round Trivium. By multiplying a polynomial reduction factor, the output Boolean polynomial is simplified. Based on this met...

AES Mixture Differential
2018/6/5
Determining the security of AES is a central problem in cryptanalysis, but progress in this area had been slow and only a handful of cryptanalytic techniques led to significant advancements. At Eurocr...
Correlation Cube Attacks: From Weak-Key Distinguisher to Key Recovery
cryptanalysis cube attack stream cipher
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...
