This chapter provides application developers with a presentation of the implemented reference implementation of the ABC4Trust architecture and protocols as well as a presentation on how to get started using the reference implementation. The reference implementation includes the ABC-Engines of the different entities, namely the User, Issuer, Verifier, Inspector, and Revocation Authority, and the smart card implementation for the User. This chapter also presents results of a perturbation analysis of the reference implementation. Even though the ABC4Trust focused on a server-desktop environment, we have done some proof of concept implementations and analysis of the feasibility of using smart phones for the user side of a Privacy-ABC setup; these results are also presented in this chapter. © Springer International Publishing Switzerland 2015.
