A Mix-Mediated Anonymity Service and Its Payment
Elke Franz, Anja Jerichow
Abstract : One measure to provide anonymity for the users of a communication network are mixes whose usage was proposed in several applications recently. However, in practice such concepts are not widely used. One reason may be that payment for providers, who commercially offer such mix-mediated anonymity service, has not been considered yet. We present detailed protocols for payment schemes that allow anonymous, secure payment of mix-mediated anonymity services. The schemes aim to achieve confidentiality and integrity for all the user, the provider and the bank.
