An efficient post-quantum KEM from CSIDH
Journal of Mathematical Cryptology, 2022 The SIDH and CSIDH are now the two most well-known post-quantum key exchange protocols from the supersingular isogeny-based cryptography, which have attracted much attention in recent years and served as the building blocks of other supersingular isogeny-

Provable security against generic attacks on stream ciphers
Journal of Mathematical Cryptology, 2023 Recent lightweight hardware-based stream cipher designs keep an external non-volatile internal state that is not part of the cipher’s hardware module. The purpose of these so-called small-state ciphers is to keep the size of the hardware and the power ...

Discretisation and Product Distributions in Ring-LWE
Journal of Mathematical Cryptology, 2020 A statistical framework applicable to Ring-LWE was outlined by Murphy and Player (IACR eprint 2019/452). Its applicability was demonstrated with an analysis of the decryption failure probability for degree-1 and degree-2 ciphertexts in the homomorphic ...

The complexity of MinRank [PDF]
, 2019 In this note, we leverage some of our results from arXiv:1706.06319 to produce a concise and rigorous proof for the complexity of the generalized MinRank Problem in the under-defined and well-defined case.

A note on secure multiparty computation via higher residue symbols
Journal of Mathematical Cryptology, 2021 We generalize a protocol by Yu for comparing two integers with relatively small difference in a secure multiparty computation setting. Yu's protocol is based on the Legendre symbol.

Persistent asymmetric password-based key exchange
Journal of Mathematical Cryptology, 2014 Asymmetric password based key exchange is a key exchange protocol where a client and a server share a low entropic password while the server additionally owns a high entropic secret with respect to a public key. There are simple solutions for this, e.g.,

Remarks on a cyclotomic sequence [PDF]
, 2008 We analyse a binary cyclotomic sequence constructed via generalized cyclotomic classes by Bai et al. (IEEE Trans Inforem Theory 51: 1849-1853, 2005).

Revisiting structure graphs: Applications to CBC-MAC and EMAC
Journal of Mathematical Cryptology, 2016 In [2], Bellare, Pietrzak and Rogaway proved an O(ℓq2/2n)${O(\ell q^{2}/2^{n})}$ bound for the PRF (pseudorandom function) security of the CBC-MAC based on an n-bit random permutation Π, provided ...

A detailed analysis of the hybrid lattice-reduction and meet-in-the-middle attack
Journal of Mathematical Cryptology, 2019 Over the past decade, the hybrid lattice-reduction and meet-in-the middle attack (called hybrid attack) has been used to evaluate the security of many lattice-based cryptographic schemes such as NTRU, NTRU Prime, BLISS and more.
