The performance analysis of public key cryptography-based authentication

open access: yesEAI Endorsed Transactions on Security and Safety, 2018
Several Kerberos-based authentication techniques using public-key cryptography have been proposed. Public-key cryptography can be used to eliminate a single point failure problem in the Key Distribution Center (KDC) and achieve better scalability. Public

Watermarking public‐key cryptographic functionalities and implementations: The case of encryption and signatures

open access: yesIET Information Security, 2021
A watermarking scheme for a public‐key cryptographic functionality enables the embedding of a mark in the instance of the secret‐key algorithm such that the functionality of the original scheme is maintained, while it is infeasible for an adversary to ...

Transitory Master Key Transport Layer Security for WSNs

open access: yesIEEE Access, 2020
Security approaches in Wireless Sensor Networks (WSNs) are normally based on symmetric cryptography. Instead of symmetric encryption, some alternative approaches have been developed by using public-key cryptography. However, the higher computational cost

Analysis of Elliptic Curve Cryptography (ECC) for Energy Efficiency in Wireless Sensor Networks

open access: yesNUST Journal of Engineering Sciences, 2009
Rapid growth of wireless sensor networks (WSN) in recent times has resulted in greater security requirements. One of the primary concerns in wireless sensor networks is energy efficiency and security mechanisms are no different.

Towards an efficient LWE‐based fully homomorphic encryption scheme

open access: yesIET Information Security, 2022
The security of most early fully homomorphic encryption schemes was based on the hardness of the Learning with Errors (LWE) problem. These schemes were inefficient in terms of per gate computations and public‐key size.

Quantum-Resistant Cryptography [PDF]

open access: yesarXiv, 2021
Quantum-resistant cryptography is cryptography that aims to deliver cryptographic functions and protocols that remain secure even if large-scale fault-tolerant quantum computers are built. NIST will soon announce the first selected public-key cryptography algorithms in its Post-Quantum Cryptography (PQC) standardization which is the most important ...

Improved Identity Based Encryption System (IIBES): A Mechanism for Eliminating the Key-Escrow Problem

open access: yesEmerging Science Journal, 2021
A revolutionary change to public-key cryptography can be considered as an Identity Based Cryptography (IBC) in which identity of the receiver is being used as a public key for encrypting a message and Key Generation Centre (KGC).
