Abstract
Summary: ``Designated verifier interactive proofs have been used as non-malleable mechanisms and to prevent man-in-the-middle attacks. In this paper we use designated 2-verifier proofs to design simple and secure electronic payment systems. Two on-line protocols are presented. These link the customer (the prover) with the merchant and bank (the two verifiers) inextricably to their transactions. In the first protocol the identity of the customer is traceable. This can be used for general electronic payment systems. The second protocol can be used for anonymous electronic cash payments. Both protocols have a simple structure and are provably secure.''
