Description
Summary:The blind signature scheme is a protocol for obtaining a signature from a signer, but the signer is unable to view the contents of the message he signs. It is very important technologies in secure e-commerce. Recently the bilinear pairing such as Weil or Tate pairing on elliptic curves and hyperelliptic curves has been found various applications in cryptography. Several ID-based cryptosystems using bilinear pairings were presented. ID-based public key cryptosystem can be a good choice for certificate-based public key infrastructures, especially when efficient key management and moderate security are required. This paper presents a new ID-based blind signature scheme from bilinear pairings. Also we analyze their efficiency and security. The proposed scheme is more efficient than Zhang and Kim's scheme.
