Abstract. Proxy partially blind signature allows a proxy signer to explicitly embed presaged common information $c$ into the blind signature without loss of blindness property. The focus of this paper is to present the efficient stamped proxy partially blind signature (SPPBS) scheme based on elliptic curve discrete logarithm problem (ECDLP) with collision-resistant cryptographic hash function which records the time stamp during signing phase of the proxy partially blind signature and to allow the original signer to revoke delegating power whenever necessary The proposed scheme satisfies all the security properties of proxy blind signature, i.e. distinguishability, nonrepudation, unforgeability, identifiability, unlinkability, and prevention of misuse. Furthermore, the proposed scheme requires minimal operation in proxy delegation, partially blinding, signing extraction and verification thus makes it very efficient. This can be implemented in low power and small processor handheld devices such as smart card, PDA etc which work in low power and small processor.
