An Identity-Based Signature Scheme with Bounded Life-Span
نویسندگان
چکیده
The aim of this paper is to present a signature scheme in which the ability to sign messages of a signer is limited to a fixed number k of signatures. It is an identity-based signature schemein which each signature can be usedonly once. We called suchschemes “bounded life-span”. It is based on mental games and it uses zero-knowledge tools. A validation center is needed to initialize this identity-based scheme. A credential center is used to insure the unicity and the bounded life-span aspects. It allows delegation and numerous practical applications.

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...
متن کاملAn 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...
متن کاملAn 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 ...
متن کاملPost-Quantum Attribute-Based Signatures from Lattice Assumptions
Attribute based signature schemes (ABS) constitute important and powerful primitives when it comes to protecting the privacy of the user’s identity and signing information. More specifically, ABS schemes provide the advantage of anonymously signing a message once a given policy is satisfied. As opposed to other related privacy preserving signatures, the verifier is not able to deduce from the s...
متن کاملIdentity-based Partial Message Recovery
We firstly proposed a new notion of short identity-based signature scheme. We argue that the identity-based environment is essential in some scenarios. The notion of short identity-based signature schemes can be viewed as identity-based (partial) message recovery signatures. Signature schemes with message recovery has been extensively studied in the literature. This problem is somewhat related ...
