Abstract: Partially blind signature is cryptographic system that is used in several protocols including e-cash and e-commerce systems. In proxy partially blind signature, part of the message is approved by the signer and the signature supplicant. Elliptic curve discrete logarithmic (ECDL) is an extremely difficult to solve problem as compared to any standard inverse operation of a one-way-trap door function including discrete logarithm problem or factorisation problem. In this paper, we propose a new proxy partially blind signature scheme based on ECDL. The main attractive features of the proposed scheme are the low computational cost and the low communication overhead. Moreover, the new scheme provides an extra level of security properties of both the partially blind signature and proxy signature. Several security analysis are shown to prove the security and the efficiency of the proposed scheme.
