In this paper the authors present a proxy blind signature scheme with forward security mechanism. The proposed digital signature scheme combines the two special-purpose signature schemes, blind signature and proxy signature. In this signature scheme, the original signer gives authority to another entity which is known as a proxy signer, but without having any idea about the content of the document. This paper, proposes an enhanced proxy blind signature, in which the forward security is incorporated and the security of the signature scheme relies on the Discrete Logarithm Problem (DLP).
