Abstract
Standardization is considered of particular importance for the dissemination of ABC4Trust results. In this deliverable, we present a brief overview of the Reference Implementation of ABC4Trust and identify its standardization-relevant parts, including the implemented protocols and XML formats, externally available APIs, policy language, and cryptographic libraries. We also consider interoperability with de-facto standard identity management schemes as an alternative to standardization, which could further ease the adoption of the Reference Implementation. Furthermore, we identify some infrastructure challenges in porting the Reference Implementation to mobile phones caused by the lack of native support for certain components of the Reference Implementation in some mobile operating systems. For all of the above, we provide a motivation for the presented discussion
points, providing not only lessons based on our experience in the design and development of the Reference Implementation, but also presenting insights on some of the challenges towards the adoption of the Reference Implementation including standardization and beyond.
