<p>The invention relates to a communication system, a method and devices for an efficient implementation of electronic transactions between a mobile subscriber in a mobile communication network and a network facility by exploiting credit card based payment protocols. The protocol, which is used for realizing a secured electronic transaction, such as the SETTM, is split over a plurality ofinvolved communication units. For realizing the invention, the first part of the protocol, which is usually contained in the mobile station of a user, is split into two parts. The first part containing the private data of a subscriber, such as the private key or the certificates, is maintained in the mobile station. The second part of the software is shifted to a server being positioned between the mobile station and the merchant. Thus, the invention guarantees on one hand the possibility of integrating complex software for an electronic way of payment in a network, which is characterized by a small transmission capacity and terminals having an insufficient storing capacity, and on the other hand the maintenance of security aspects on the user side. Additionally, the invention guarantees the compatibility with the already existing software.</p> |
