A new code‐based digital signature based on the McEliece cryptosystem

IET Communications, 2023
Digital signature schemes are used for the authentication and verification of signatures. The Courtois–Finiasz–Sendrier (CFS) digital signature is a well‐known code‐based digital signature scheme based on the Niederreiter cryptosystem. However, it is not

Efficient and Anonymous Certificateless Multi-Message and Multi-Receiver Signcryption Scheme Based on ECC

IEEE Access, 2019
As the further extension of the multi-receiver signcryption, the multi-message and multi-receiver signcryption allows a sender to simultaneously signcrypt different messages for different receivers in only one logic operation, which makes it more ...

Extended supersingular isogeny Diffie–Hellman key exchange protocol: Revenge of the SIDH

IET Information Security, 2021
The supersingular isogeny Diffie–Hellman key exchange protocol (SIDH) was introduced by Jao and De Feo in 2011. SIDH operates on supersingular elliptic curves defined over Fp2, where p is a large prime number of the form p=4eA3eB−1 and eA and eB are ...

Agri-Food Traceability Management using a RFID System with Privacy Protection [PDF]

, 2007
In this paper an agri-food traceability system based on public key cryptography and Radio Frequency Identification (RFID) technology is proposed. In order to guarantee safety in food, an efficient tracking and tracing system is required.

Lossless and Reversible Data Hiding in Encrypted Images With Public Key Cryptography

Rice, 2017
— The Lossless data hiding provides the embedding of data in a host image without any loss of data. This research explain a lossless data hiding and image cryptography method based on Choas - Block to image encryption the lossless means if the marked ...

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

IET 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 ...
