Abstract

A partially blind signature scheme allows the signer to inoculate a non-removable common information into his blind signature. This common information may represent the date or the amount of e-cash. Due to its un-traceablility and partial blindness property, the partially blind signature plays an important role in many e-commerce applications. Based on the RSA scheme, we propose a partially blind threshold signature with low-computational load for the client.
