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...
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...
Cube attacks are an important type of key recovery attacks against stream ciphers. In particular, it is shown to be powerful against Trivium-like ciphers. Traditional cube attacks are experimental att...
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...
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...
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...
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...
In this paper, we propose a key-recovery attack on Trivium reduced to 855 rounds. As the output is a complex Boolean polynomial over secret key and IV bits and it is hard to find the solution of the s...
This paper proposes a simple single bit flip fault attack applicable to several LWE (Learning With Errors Problem) based lattice based schemes like KYBER, NEWHOPE, DILITHIUM and FRODO which were submi...
Lightweight block ciphers rely on simple operations to allow compact implementation. Thanks to its efficiency, bit permutation has emerged as an optimal choice for state-wise diffusion. It can be impl...
Post-quantum cryptography has attracted much attention from worldwide cryptologists. At Asiacrypt 2017, Leander and May combines Grover and Simon algorithms to quantumly break FX-based block ciphers. ...
Chen et al. proved that two variants of the two-round n-bit Even-Mansour ciphers are secure up to 22n/3 queries against distinguish- ing attacks. These constructions can be regarded as minimal two-rou...
AEZ is an authenticated encryption algorithm, submitted to the CAESAR competition. It has been selected for the third round of the competition. While some classical analysis on the algorithm have been...
In the quantum model, by utilizing the Simon's algorithm, we propose an efficient universal forgery attack to FKS, FKD and Keyak with complexity of O(c)O(c). Moreover, we also propose an efficient key...
We propose a public key infrastructure framework, inspired by modern distributed cryptocurrencies, that allows for tunable key escrow, where the availability of key escrow is only provided under stric...
