Signature scheme based on bilinear 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.A new digital signature scheme and a blind signature scheme are proposed by using the bilinear property of Weil pairing defined on elliptic curves,and their security and applications are also analyzed.The safety of this scheme is based on the elliptic curve discrete logarithm of non-singular elliptic curve over finit field,which has no efficient attack up to now.It is secure,the operation of it is convenient and the implementation is easier as well.
