Description
Summary:E-Cash is a medium of anonymous payment in e-Commerce. Recently, L. Shi introduced conditional e-cash for enabling electronic payment to be based on the outcome of a certain single condition. We construct a new secure e-cash scheme to solve the open problem of multiple conditional payment. In our scheme, multiple conditions can build a complex condition by AND and OR operations, while the only need for a publisher is publishing information on the result of every simple condition. This e-cash scheme achieves many properties, such as transferability, anonymity, unforgeability and so on. Furthermore, we modify the scheme into supporting multiple publishers.
