Speed protocol: Smartcard-based payment with encrypted electronic delivery

Abstract

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