Towards Isogeny-Based Password-Authenticated Key Establishment
Journal of Mathematical Cryptology, 2020 Password authenticated key establishment (PAKE) is a cryptographic primitive that allows two parties who share a low-entropy secret (a password) to securely establish cryptographic keys in the absence of public key infrastructure.

A cryptographic primitive based on hidden-order groups
Journal of Mathematical Cryptology, 2009 Let G1 be a cyclic multiplicative group of order n. It is known that the computational Diffie–Hellman (CDH) problem is random self-reducible in G1 if φ(n) is known.

Cryptanalysis of a Pairing-free Certificateless Signcryption scheme
ICT Express, 2021 Signcryption is a very useful cryptographic primitive that aims to achieve authentication and confidentiality in an efficient manner. We cryptanalyze the signcryption scheme of Wei and Ma (2019) which is claimed to be secure.

Sound Hashing Modes of Arbitrary Functions, Permutations, and Block Ciphers
IACR Transactions on Symmetric Cryptology, 2018 Cryptographic hashing modes come in many flavors, including Merkle-Damgård with various types of strengthening, Merkle trees, and sponge functions. As underlying primitives, these functions use arbitrary functions, permutations, or block ciphers. In this

A device-independent protocol for XOR oblivious transfer [PDF]
Quantum, 2022 Oblivious transfer is a cryptographic primitive where Alice has two bits and Bob wishes to learn some function of them. Ideally, Alice should not learn Bob's desired function choice and Bob should not learn any more than what is logically implied by the ...

Implementation and Optimization of Zero-Knowledge Proof Circuit Based on Hash Function SM3
Sensors, 2022 With the increasing demand for privacy protection in the blockchain, the universal zero-knowledge proof protocol has been developed and widely used. Because hash function is an important cryptographic primitive in a blockchain, the zero-knowledge proof ...

Quantum advantage for probabilistic one-time programs
Nature Communications, 2018 Information Theoretically-secure deterministic programs that self-destruct after a single use are known to be impossible to implement. Here, the authors use quantum states to implement a probabilistic version of this fundamental cryptographic primitive ...
