Abstract

For a shopping mobile agent that collects offers from vendors’ servers on behalf of its owner, offer privacy is an important property. In this paper, we propose a protocol using a “conditionally anonymous digital signature scheme” to achieve offer privacy based on a fair blind signature. The proposed scheme provides a method for a server to sign its offer without revealing any information about its identity to any other server or the originator. When a server’s identity needs to be revealed, the offer privacy can be reversed, with the assistance of the e-market authority.
