A Key-Recovery Side-Channel Attack on Classic McEliece Implementations
Transactions on Cryptographic Hardware and Embedded Systems, 2022 In this paper, we propose the first key-recovery side-channel attack on Classic McEliece, a KEM finalist in the NIST Post-quantum Cryptography Standardization Project.

A Direct Key Recovery Attack on SIDH
, 2023 We present an attack on SIDH utilising isogenies between polarized products of two supersingular elliptic curves. In the case of arbitrary starting curve, our attack (discovered independently from [8]) has subexponential complexity, thus significantly reducing the security of SIDH and SIKE. When the endomorphism ring of the starting curve is known, our

Towards Key-recovery-attack Friendly Distinguishers: Application to GIFT-128
IACR Transactions on Symmetric Cryptology, 2021 When analyzing a block cipher, the first step is to search for some valid distinguishers, for example, the differential trails in the differential cryptanalysis and the linear trails in the linear cryptanalysis.

Improved integral attack——random linear distinguish and key recovery attack
Tongxin xuebao, 2023 Based on the integral attack and collision attack of four rounds of AES, a random linear distinguish attack against four rounds of SP block ciphers was proposed, which took advantage of the non-uniformity of linear biases’ distribution between some ...

Lattice Attacks on NTRU Revisited
IEEE Access, 2021 NTRU cryptosystem was proposed by J. Hoffstein, J.Pipher and J.H. Silverman in 1996, whose security is related to the hardness of finding sufficient short vectors in NTRU lattice with dimension $2N$ .

A Key Recovery Attack on Edon80 [PDF]
, 2007 Edon80 is a recent stream cipher design that has advanced to the third and last phase of the eSTREAM project. It has remained unbroken and untweaked since it was designed and submitted to eSTREAM. It is now one of the 8 final hardware candidates. In this paper we cryptanalyze the cipher by describing a key recovery attack.

Key recovery attack on Hufu-UOV
JSIAM Letters, 2022 Summary: The unbalanced oil and vinegar signature scheme (UOV) is a signature scheme whose public key is a set of quadratic polynomials over a finite field. This scheme has been considered to be secure and efficient enough under suitable parameter selections.

Generic attacks on small-state stream cipher constructions in the multi-user setting
Cybersecurity, 2023 Small-state stream ciphers (SSCs), which violate the principle that the state size should exceed the key size by a factor of two, still demonstrate robust security properties while maintaining a lightweight design.
