APTE: An Algorithm for Proving Trace Equivalence [PDF]
, 2014 This paper presents APTE, a new tool for automatically proving the security of cryptographic protocols. It focuses on proving trace equivalence between processes, which is crucial for specifying privacy type properties such as anonymity and unlinkability.

A Novel Design of Cryptographic SP-Network Based on Gold Sequences and Chaotic Logistic Tent System
IEEE Access, 2019 Substitution permutation network (SP-network) is a chain of linked mathematical primitives used in block cipher algorithms. The proposed novel design of cryptographic SP-network consists of three cryptographic primitives: substitution box, permutation ...

Key Assignment Scheme with Authenticated Encryption
IACR Transactions on Symmetric Cryptology, 2018 The Key Assignment Scheme (KAS) is a well-studied cryptographic primitive used for hierarchical access control (HAC) in a multilevel organisation where the classes of people with higher privileges can access files of those with lower ones.

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.

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.

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.

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 ...

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
