On the Design of Cryptographic Primitives [PDF]
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 ...

Secure and Computationally-Efficient Cryptographic Primitive based on Cellular Automation [PDF]
Mageto, a random number generator based on one-dimensional cellular automaton (CA) is presented. Three procedures of secure implementation using Mageto is proposed and discussed. Implementations are very efficient in a wide range of hardware and software scenarios.

A language-dependent cryptographic primitive [PDF]
In this paper we provide a new cryptographic primitive that generalizes several existing zero-knowledge proofs and show that if a languageL induces the primitive, then there exists a perfect zero-knowledge proof forL. In addition, we present several kinds of languages inducing the primitive, some of which are not known to have a perfect zero-knowledge ...

Post-Quantum Cryptographic Hardware Primitives [PDF]
The development and implementation of post-quantum cryptosystems have become a pressing issue in the design of secure computing systems, as general quantum computers have become more feasible in the last two years. In this work, we introduce a set of hardware post-quantum cryptographic primitives (PCPs) consisting of four frequently used security ...

A cryptographic primitive based on hidden-order groups [PDF]
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.

Verification of a Cryptographic Primitive [PDF]
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. Verifiable C is a separation logic for the C language, proved sound with respect to the operational semantics for

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

A Novel Design of Cryptographic SP-Network Based on Gold Sequences and Chaotic Logistic Tent System
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 ...

Multipurpose Cryptographic Primitive ARMADILLO3 [PDF]
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 in blockchains
Abstract Blockchain, as one of the crypto-intensive creatures, has become a very hot topic recently. Although many surveys have recently been dedicated to the security and privacy issues of blockchains, there still lacks a systematic examination on the cryptographic primitives in blockchains.
