The impossible differential (ID) attack is one of the most important cryptanalytic techniques for block ciphers. There are two phases to finding an ID attack: searching for the distinguisher and building a key recovery upon it. Previous works only fo

Multivariate quadratic equation-based cryptographic algorithms are one of the promising post-quantum alternatives to current public-key cryptographic algorithms based on the discrete logarithm problem and the integer factorization problem. In this pa

The stream cipher ChaCha has been subjected to differential linear cryptanalysis since 2008. Aumasson et al. (2008) laid the groundwork for this attack, employing the concept of probabilistically neutral bits for key recovery. Subsequently, various e

Recently, Chait et al. proposed a new aggregate signature scheme under the RSA setting (IEEE Access, 2023). In this paper, we show that Chait et al.’s aggregate signature scheme is insecure when two signers collude with their own secret keys, by pr

This paper examines the security of Rocca, an authenticated encryption algorithm designed for Beyond 5G/6G contexts. Rocca has been revised multiple times in the initialization and finalization for security reasons. In this paper, we study how the ch

Because of the substantial progress in quantum computing technology, the safety of traditional cryptologic schemes is facing serious challenges. In this study, we explore the quantum safety of the lightweight cipher MIBS and propose quantum key-recov

This paper presents practicable single trace attacks against the Hamming Quasi-Cyclic (HQC) Key Encapsulation Mechanism. These attacks are the first Soft Analytical Side-Channel Attacks (SASCA) against code-based cryptography. We mount SASCA based on

In recent research, Durandal, a signature scheme based on rank metrics following Schnorr's approach, was introduced to conceal secret key information by selectively manipulating the vector subspace of signatures. Later, an enhancement, namely the SHM

The LowMC family of SPN block cipher proposed by Albrecht et al. was designed specifically for MPC-/FHE-/ZKP-friendly use cases. It is especially used as the underlying block cipher of PICNIC, one of the alternate third-round candidate digital signat
