A Practical Multivariate Blind Signature Scheme
نویسندگان
چکیده
Multivariate Cryptography is one of the main candidates for creating post-quantum cryptosystems. Especially in the area of digital signatures, there exist many practical and secure multivariate schemes. However, there is a lack of multivariate signature schemes with special properties such as blind, ring and group signatures. In this paper, we propose a technique to transform the Rainbow multivariate signature schemes into a blind signature scheme. The resulting scheme satisfies the usual blindness criterion and a one-more-unforgeability criterion adapted to MQ signatures, produces short blind signatures and is very efficient.

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 ...

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...
متن کاملDouble 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 کاملMQSAS - A Multivariate Sequential Aggregate Signature Scheme
(Sequential) Aggregate signature schemes enable a group of users u1, . . . , uk with messages m1, . . . ,mk to produce a single signature Σ which states the integrity and authenticity of all the messages m1, . . . ,mk. The length of the signature Σ is thereby significantly shorter than a concatenation of individual signatures. Therefore, aggregate signatures can improve the efficiency of numero...
متن کاملA Practical Coalition-resistant Group Blind Signature Scheme
A group signature allow any member of a group to sign on behalf of the group. A group blind signature requires that a group member signs on group’s behalf a document without knowing its content. In this paper we propose a practical coalition-resistant group blind signature scheme based on the strong RSA and the decisional Diffie-Hellman assumptions. Our scheme is an extension of the group signa...
