The Design of Multi-proxy Blind Signature Scheme

Multi-proxy signature is a special digital signature technology,it means an original signer can authorize a group of proxy signers to sign on behalf of him.In a blind signature scheme,the signer cannot make a linkage between the signature and the identity of the user.Combining multi-proxy signature with blind signature,a multi-proxy blind signature scheme from bilinear pairings is proposed,which is secure and efficient.In the scheme,blind signature can be performed by multi proxy signers and delegation can be transmitted through public channel.
