An improved identity-based ring signature scheme from bilinear pairings
Lin-Wu’s ID-based ring signature scheme from bilinear pairings is unreasonable. In this paper, we improve it, and obtain a reasonable ID-based ring signature scheme from bilinear pairings.
متن کاملID-Based Blind Signature and Ring Signature from Pairings
Recently the bilinear pairing such as Weil pairing or Tate pairing on elliptic curves and hyperelliptic curves have been found various applications in cryptography. Several identity-based (simply ID-based) cryptosystems using bilinear pairings of elliptic curves or hyperelliptic curves were presented. Blind signature and ring signature are very useful to provide the user’s anonymity and the sig...
متن کاملNew Proxy Signature, Proxy Blind Signature and Proxy Ring Signature Schemes from Bilinear Pairings
Proxy signatures are very useful tools when one needs to delegate his/her signing capability to other party. After Mambo et al.’s first scheme was announced, many proxy signature schemes and various types of proxy signature schemes have been proposed. Due to the various applications of the bilinear pairings in cryptography, there are many IDbased signature schemes have been proposed. In this pa...
متن کاملAn Efficient Signature Scheme from Bilinear Pairings and Its Applications
In Asiacrypt2001, Boneh, Lynn, and Shacham [8] proposed a short signature scheme (BLS scheme) using bilinear pairing on certain elliptic and hyperelliptic curves. Subsequently numerous cryptographic schemes based on BLS signature scheme were proposed. BLS short signature needs a special hash function [6, 1, 8]. This hash function is probabilistic and generally inefficient. In this paper, we pro...
