摘要： The present invention relates electronic receipts. There is provided a method for generating an electronic receipt in a communication system providing a public key infrastructure, the method comprising the steps of receiving by a second party a request message from a first party, the request message comprising a transaction request and a first public key based on a secret owned by the first party and wherein the secret is associated with at least the secret of a further public key of the first party, electronically signing at least part of the request message with a second public key assigned to the second party to issue the electronic receipt, and providing the electronic receipt to the first party. Further, there is provided a method for verifying the ownership of an electronic receipt in a communication system providing a public key infrastructure, the verification arising out of a series of messages being sent and received between a first party and a verifying party, the method comprising the steps of receiving a proof message from the first party, the proof message being derived from at least a first public key based on a secret owned by the first party and wherein the secret is associated with at least the secret of a further public key of the first party and an electronic receipt that has been issued by electronically signing a request message with a second public key, determining whether or not the proof message was derived from the second public key.
