Application of identity-based blind signature in e-cash payment
Song Chun-lai · Journal of Hefei University of Technology · 2007
The paper deals with the application of identity-based blind signature based on bilinear pairings to the e-cash payment system.The public key of the identity-based cryptographic system is computed by the signatory's identity.In the scheme,a center bank is set up,then the bank which intends to issue the e-cash lodges an application to the center bank.The bank's public key is computed by its identity,and the private key is generated by the center bank.This scheme has high security and efficiency.
