A Study on the Parameter Size of the Montgomery Trick for ECDLP

2018 International Symposium on Information Theory and Its Applications (ISITA), 2018
In this research, the choice of the parameter of the Montgomery trick in Pollard’s Rho method to solve the elliptic curve discrete logarithm problem for Barreto-Naehrig (BN) curves is shown. The average number of generated rational points per unit time is chosen as a measure of the effectiveness of the choice of the parameter of the Montgomery trick ...

A Novel Protocol for Smart Card Using ECDLP

2008 First International Conference on Emerging Trends in Engineering and Technology, 2008
In this paper, we propose a novel protocol for smart card based on elliptic curve discrete logarithm problem (ECDLP). We believe that applications of smart card technology should be benefited more from advantages of public key cryptography, specifically, in initiation and maintenance of secure channel.

Solving ECDLP via List Decoding

2019
We provide a new approach to the elliptic curve discrete logarithm problem (ECDLP). First, we construct Elliptic Codes (EC codes) from the ECDLP. Then we propose an algorithm of finding the minimum weight codewords for algebraic geometry codes, especially for the elliptic code, via list decoding.

ECDLP Based Proxy Multi-signature Scheme

2012
A Proxy signature scheme enables a proxy signer to sign a message on behalf of the original signer. In this paper, we propose efficient and secure Proxy multi-signature scheme based on elliptic curve cryptosystem. Our scheme satisfy all the proxy requirements and require only elliptic curve multiplication and elliptic curve addition which needs less ...

A New Digital Proxy Signature Scheme Based on ECDLP

2009 International Conference on Computational Intelligence and Security, 2009
In the proxy signature scheme the proxy signer has the power to act on behalf of the original signer. In order to overcome the security threats and weaknesses in existing schemes, a new proxy signature based on elliptic curve cryptosystem (ECC) is presented.

ECDLP‐based certificateless proxy signature scheme with message recovery

Transactions on Emerging Telecommunications Technologies, 2012
AbstractCertificateless public key cryptography (PKC) eliminates the use of certificates in traditional PKC and the key escrow problem in identity‐based PKC. Up to now, a number of certificateless proxy signature (CLPS) schemes have been proposed. However, only a little attention has been paid to the construction of CLPS schemes with message recovery ...

An ECDLP based untraceable blind signature scheme

2013 International Conference on Circuits, Power and Computing Technologies (ICCPCT), 2013
In this paper we presents an Elliptic Curve Discrete Logarithm Problem (ECDLP) based blind signature scheme. Elliptic Curve Cryptosystem is the best known public-key cryptosystem till date, and is suitable for resource constrained environment because of smaller key size.

Some basic principles for proxy signature schemes based on ECDLP

Proceedings of the 6th International ICST Conference on Collaborative Computing: Networking, Applications, Worksharing, 2010
Nowadays, most proxy signature schemes are based on the difficulty of DLP (Discrete Logarithm Problem) or ECDLP (Elliptical Curve Discrete Logarithm Problem). As though many proxy signature schemes based on DLP or ECDLP have been proposed, it makes us discouraged that some disadvantages can be found after a new or modified proxy signature scheme was ...

A Proposed Developments of Pollards Rho Method for Attacking the ECDLP

2021 7th International Engineering Conference “Research & Innovation amid Global Pandemic" (IEC), 2021
In cryptography, an attack is a method of solving a problem related to cryptosystem. Specifically, the aim of an attack is to find suitable fast method of solving a problem on which an encryption algorithm depends, or to find the secret key for encryption algorithm.

Quantum Attacks on ECDLP-Based Cryptosystems

2013
In this chapter we shall first study the elliptic curve discrete logarithm problem (ECDLP) and the classical solutions to ECDLP, and then we shall discuss some of the most popular ECDLP-based cryptographic systems for which there is no efficient cryptanalytic algorithm.
