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...
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...
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. ...
We present a key-recovery attack against MANTIS-5 with 228228 chosen plaintexts and a computational complexity of about 238238 block cipher calls, which violates this claim. Our attack is based on a f...
We introduce a new technique for doing the key recovery part of an integral or higher order differential attack. This technique speeds up the key recovery phase significantly and can be applied to a...
Algorithms for secure encryption in a post-quantum world are currently receiving a lot of attention in the research community, including several larger projects and a standardization effort from NIST....
In this paper, we propose a guess and determine attack against some variants of the π-Cipher family of authenticated ciphers. This family of ciphers is a second-round candidate of the CAESAR comp...
FASER is a family of authenticated ciphers submitted to the CAESAR competition, which contains two parent ciphers: FASER128 and FASER256. In this work we only focus on FASER128 and present a key re...
One of the interesting types of RFID application is RFID searching which aims to hear a specific RFID tag from a large group of tags, i.e. ability of detecting whether a target RFID tag is nearby. Ver...
We investigate the security of the family of MQQ public key cryptosystems using multivariate quadratic quasigroups (MQQ). These cryptosystems show especially good performance properties. In particul...
In this paper we present a key recovery attack to the scale-invariant NTRU-based somewhat homomorphic encryption scheme proposed by Bos et al~\cite{NTRUbasedFHE} in 2013. The attack allows us to compu...
We propose new generic key recovery attacks on Feistel-type block ciphers. The proposed attack is based on the all subkeys recovery approach presented in SAC 2012, which determines all subkeys inste...
We present a cryptanalysis of the ASASA public key cipher introduced at Asiacrypt 2014. This scheme alternates three layers of affine transformations A with two layers of quadratic substitutions S. We...
In this letter we report on an ultra-efficient key recovery attack under the chosen-plaintext-attack model against the stream cipher A2U2, which is the most lightweight cryptographic primitive (i.e., ...
