On the security and the efficiency of the Merkle signature scheme

چکیده

This paper builds on the multi-time signature scheme proposed by Merkle. We prove that the original scheme is existentially unforgeable under adaptive chosen message attack. Moreover, we present an improved version which has three advantages: It is provably forward secure. The number of signatures that can be made with one private key is — in a practical sense — unlimited. Finally, the cost for key generation is kept low. The theoretical exposition is complemented by experimental data about the efficiency of the improved Merkle signature scheme.

Double voter perceptible blind signature based electronic voting protocol

Mu et al. have proposed an electronic voting protocol and claimed that it protects anonymity of voters, detects double voting and authenticates eligible voters. It has been shown that it does not protect voter's privacy and prevent double voting. After that, several schemes have been presented to fulfill these properties. However, many of them suffer from the same weaknesses. In this p...

An ECC-Based Mutual Authentication Scheme with One Time Signature (OTS) in Advanced Metering Infrastructure

Advanced metering infrastructure (AMI) is a key part of the smart grid; thus, one of the most important concerns is to offer a secure mutual authentication.  This study focuses on communication between a smart meter and a server on the utility side. Hence, a mutual authentication mechanism in AMI is presented based on the elliptic curve cryptography (ECC) and one time signature (OTS) consists o...

An efficient blind signature scheme based on the elliptic curve discrete logarithm problem

Elliptic Curve Cryptosystems (ECC) have recently received significant attention by researchers due to their high performance such as low computational cost and small key size. In this paper a novel untraceable blind signature scheme is presented. Since the security of proposed method is based on difficulty of solving discrete logarithm over an elliptic curve, performance of the proposed scheme ...

Post-quantum signatures for today

Digital signatures are essential for the security of computer networks such as the Internet. For example, digital signatures are widely used to ensure the authenticity and integrity of updates for operating systems and other software applications. The security of the few practically used signature schemes is threatened by quantum computers. When large quantum computers are built, all currently ...

The new protocol blind digital signature based on the discrete logarithm problem on elliptic curve

In recent years it has been trying that with regard to the question of computational complexity of discrete logarithm more strength and less in the elliptic curve than other hard issues, applications such as elliptic curve cryptography, a blind  digital signature method, other methods such as encryption replacement DLP. In this paper, a new blind digital signature scheme based on elliptic curve...
