Electronic business and yet many of its aspects in our everyday life attract the interest of investors, managers and entrepreneurs. Efforts to modernize both the public and private sector through the use of Information communication technologies have led over the recent years into the implementation of large and complex information systems. SOA architectures via business process management techniques have managed to deal with those complexity issues. The new generation of distributed information systems is primarily based on the use of Web services which in turn make use of the XML language, so as to communicate with each other, facing essentially the requirement for platform independence. Meanwhile, security requirements are growing accordingly, especially if one considers that data exchanged in such processes are mostly economic. Main objective of the present diploma thesis is the implementation - using the BPMN standard – of a business workflow operation for a predefined Web service, thus highlighting functional gaps in security, but also proposing a related mechanism, applied on the issuance of the (XML) electronic invoice. As a main step of the used methodology, the most suitable business process modeling software environment for the needs of this paper was carefully selected. Design and implementation of the selected Web service’s standard business workflow are presented in detail, while additionally due to the qualification of XML digital signature as the proposed security solution by appliance on the presented implementation, details on e-Invoicing are also listed, focusing on those that apply within the European Union and consequently within Greece.
