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 ...
متن کاملID-based Ring Signature and Proxy Ring Signature Schemes from Bilinear Pairings
In 2001, Rivest et al. firstly introduced the concept of ring signatures. A ring signature is a simplified group signature without any manager. It protects the anonymity of a signer. The first scheme proposed by Rivest et al. was based on RSA cryptosystem and certificate based public key setting. The first ring signature scheme based on DLP was proposed by Abe, Ohkubo, and Suzuki. Their scheme ...
متن کاملAn Identity-based Mediated Signature Scheme from Bilinear Pairing
It has always been a critical issue to find efficient methods for fast revocation of a user’s identity in identity (ID)based cryptosystems. Unfortunately, none of the previous ID-based cryptography can find a practical way. Libert et al. and Baek et al. respectively propose an ID-based mediated encryption scheme based on the practical ID-based encryption scheme from bilinear pairing due to Bone...
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 کاملID-based Threshold Blind Signature scheme from Bilinear Pairing
Threshold and Blindness are two important properties in cryptography system. They can provide security and privacy. In this paper, We present an efficient construction from Bilinear pairing in an ID-based cryptography system. In an ID-based (k, n) threshold blind signature scheme, Private Key Generation Center(PKGC) distributes the secret key to n group members. The user only communicates with ...
