This paper describes an enhancement and implementation of an existing inter-enterprise role-based authorisation scheme for electronic transactions in the context of the Internet. For the enhancement, an abstract model and proof of its essential properties are given. The implementation is documented by text and class diagrams. Finally, some screenshots of a running demonstrator application are provided to illustrate the working of the scheme.
