Public Key Protocols over Skew Dihedral Group Rings
Mathematics, 2022 This paper introduces skew dihedral group rings and their applications for public-key cryptography. We present a specific skew group ring that is the underlying algebraic platform for our cryptographic constructions.

A Constant-time AVX2 Implementation of a Variant of ROLLO
Transactions on Cryptographic Hardware and Embedded Systems, 2021 This paper introduces a key encapsulation mechanism ROLLO+ and presents a constant-time AVX2 implementation of it. ROLLO+ is a variant of ROLLO-I targeting IND-CPA security. The main difference between ROLLO+ and ROLLO-I is that the decoding algorithm of

INAKA: Improved Authenticated Key Agreement Protocol Based on Newhope
IEEE Access, 2020 The Newhope scheme is one of the milestones of the study in key agreement protocol but it lacks the anti-active-attack capability. In this article, we propose a mutual authenticated key agreement scheme named INAKA scheme based on the commitment value ...

Energy Efficiency Analysis of Post-Quantum Cryptographic Algorithms
IEEE Access, 2021 Classical cryptographic schemes in use today are based on the difficulty of certain number theoretic problems. Security is guaranteed by the fact that the computational work required to break the core mechanisms of these schemes on a conventional ...

Dynamic key ring update mechanism for mobile wireless sensor networks [PDF]
, 2013 Key distribution is an important issue to provide security in Wireless Sensor Networks (WSNs). Many of the key pre-distribution schemes proposed for static WSNs perform poorly when they are applied to Mobile Wireless Sensor Networks (MWSNs).
