An ID-based Blind Signature Scheme from Bilinear Pairings
نویسنده
چکیده
Blind signatures, introduced by Chaum, allow a user to obtain a signature on a message without revealing any thing about the message to the signer. Blind signatures play an important role in plenty of applications such as e-voting, e-cash system where anonymity is of great concern. Identity based(ID-based) public key cryptography can be a good alternative for certificate based public key setting, especially when efficient key management and moderate security are required. In this paper, we propose an IDbased blind signature scheme from bilinear pairings. The proposed scheme is based on the Hess IDbased digital signature scheme. Also we analyze security and efficiency of the proposed scheme.

ID-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 کاملOne-Round ID-Based Blind Signature Scheme without ROS Assumption
In this paper, we propose a new ID-based blind signature scheme based on bilinear pairings from scratch (i.e. without using existing ID-based signature schemes, and without using existing computational assumptions). First, the round complexity of our ID-based blind signature scheme is optimal. Namely, each interactive signature generation requires the requesting user and the signer to transmit ...
