On April 24, 2015 the ITU Workshop on "Future Trust and Knowledge Infrastructure" took place in Geneva, Switzerland. The workshop’s goal was to stimulate discussion on future converged ICT services and information infrastructure.

In the workshop's second session, which addressed "Requirements and Expectations for Future ICT Infrastructure" UZH held a presentation on "Tussles for Edge Network caching". The Tussle Analysis was standardized in ITU-T Recommendation Y.3013 – in main parts driven by SmartenIT, FLAMINGO, and UZH – to complement future network design and standardization by a suitable socio-economic assessment.

In this talk the Tussle Analysis was applied to a major SmartenIT scenario, especially to analyze and predict socio-economic consequences, when content from social networks is cached in nano Data Centers (uNaDa). uNaDas reside at end-users' premises and are under their control. The talk outlined the most important stakeholders for this technology, their interests, and conflicts between them. It was also proposed to mitigate two of the conflicts by distributing encrypted content via unencrypted connection with unencrypted headers. This will allow to cache the content and to provide access to the information by centrally handled keys.

Since there were several security and trust experts in the audience, valuable feedback on the proposed solution and evaluation was received. Therefore, UZH’s presentation not only ensured SmartenIT’s visibility in a world-wide established and influential standardization organization, it also provided the basis for the establishment of a valuable feedback for the project to further improve the developed uNaDa caching strategies.
