OpenSST based Clearing Mechanism for e-Business

OpenSST is a protocol for secured electronic transactions. This article presents an experimental prototype of the OpenSST protocol within the framework of electronic transactions. It will be an e-Business architecture around which a component is graft in charge of executing authorization requests for electronic payments. This architecture is already deployed on an e-Business platform (EBSME3: Electronic Business for SMEs). Most often, the clearing communication support (authorization requests) is ensured by a leased line. In addition to the fact of using the Internet to proceed the banking authorizations of payment, adopting OpenSST as the basic protocol for the transport of the authorization of payment messages get us the following advantages: safety, simplicity and open source. OpenSST was developed to answer three major requirements. The first requirement was to reach a high security level . This security is based in term of confidentiality, integrity, authentication and non-repudiation. The second requirement was the needed simplicity in software engineering, which proves to be a significant factor for the design of information systems. The third and the last major requirement was the ability to accept and use existing standards in order to ensure an easy interfacing with other solutions. To reach these exigencies, the OpenSST protocol was build on a standardized message format, which is composed in one part by a message structure, and on the other part by the operation of the protocol.
