Verification of a Cryptographic Primitive

open access: yesACM Transactions on Programming Languages and Systems, 2015
This article presents a full formal machine-checked verification of a C program: the OpenSSL implementation of SHA-256. This is an interactive proof of functional correctness in the Coq proof assistant, using the Verifiable C program logic.

Multipurpose Cryptographic Primitive ARMADILLO3 [PDF]

open access: yesSmart Card Research and Advanced Application Conference, 2012
This paper describes a new design of the multipurpose cryptographic primitive ARMADILLO3 and analyses its security. The ARMADILLO3 family is oriented on small hardware such as smart cards and RFID chips. The original design ARMADILLO and its variants were analyzed by Sepehrdad et al.

Cryptographic primitives based on cellular transformations [PDF]

open access: yesComputer Science Journal of Moldova, 2003
Design of cryptographic primitives based on the concept of cellular automata (CA) is likely to be a promising trend in cryptography. In this paper, the improved method performing data transformations by using invertible cyclic CAs (CCA) is considered ...

On the Use of GF-Inversion as a Cryptographic Primitive [PDF]

open access: yesACM Symposium on Applied Computing, 2003
Inversion in Galois Fields is a famous primitive permutation for designing cryptographic algorithms e.g. for Rijndael because it has suitable differential and linear properties. Inputs and outputs are usually transformed by addition (e.g. XOR) to key bits. We call this construction the APA (Add-Permute-Add) scheme.

On the Design of Cryptographic Primitives [PDF]

open access: yesActa Applicandae Mathematicae, 2006
The main objective of this work is twofold. On the one hand, it gives a brief overview of the area of two-party cryptographic protocols. On the other hand, it proposes new schemes and guidelines for improving the practice of robust protocol design. In order to achieve such a double goal, a tour through the descriptions of the two main cryptographic ...

Experimental cheat-sensitive quantum weak coin flipping

open access: yesNature Communications, 2023
Quantum-enhanced versions of weak coin flipping (a cryptographic primitive where two mistrustful parties agree on a random bit while favouring opposite outcomes) have been proposed in the past but never realised.

New number-theoretic cryptographic primitives [PDF]

open access: yesJournal of Mathematical Cryptology, 2020
Abstract This paper introduces new p r q -based one-way functions and companion signature schemes. The new signature schemes are interesting because they do not

Towards Lightweight Provable Data Possession for Cloud Storage Using Indistinguishability Obfuscation

open access: yesIEEE Access, 2022
Cloud Computing has proved to be a boon for many individuals and organizations who cannot afford infrastructure and maintenance cost of resources. But the untrusted nature of Cloud Server (CS) brings many challenges related to security and trust.
