In these times of the dawning of e-commerce, many issues and barriers still remain to be solved before electronic transactions over the Web can be expected to be really successful. One important unresolved problem is the issue of having efficient and secure payment models based on e-purses and including electronic product delivery and price negotiation. In response to this need, the SPEED protocol specification has been proposed. This specification, which is described in this paper, provides a high level of security for all parties involved in e-commerce transactions over the Internet; at the same time, we have combined this aim with the use of highly-recognised standards and all the advantages of using e-purses implemented on multiaplication smart cards. Our work has also been tested in a real environment, providing us an interesting feedback based on technical and user-friendly matters.
