The API we implemented confirmed also that the schemes
we proposed are feasible in practice and quite flexible, and
they can be tailored for clients with specific additional constratins
by possibly dropping some of the requirements we
identified. Besides, the analysis we provide of the different
solutions can help assessing the security risk of dropping a
requirement in favor, for instance, of a smoother integration
and usability as in the case of the secure storage solution for
the current openXdata client described in the previous section.
