A Secure and Efficient Proxy Blind Signature Scheme without Bilinear Pairing

ABSTRACT

A proxy blind signature is a type of digital signatures that includes the properties of both proxy and blind signature. Therefore, a proxy blind signature also includes a blind signature. Many proxy blind signature schemes are not effective or convenient. According to this scheme, the proxy signer has the power to produce a blind signature in the original signers place. The proxy blind signature scheme is very useful in electronic cash payment system. In this paper we proposed a secure and efficient proxy blind signature scheme without bilinear pairing. The proposed scheme satisfies the security requirement of proxy signature scheme and blind signature scheme. We also analysis the performance of our scheme with Tan et al.[3], Yang et al.[24] and Qi et al.[25] scheme. The security of the proposed scheme is based on Elliptic Curve Discrete Logarithm Problem (ECDLP).
