To mesh or not to mesh: flexible wireless indoor communication among mobile robots in industrial environments
Mobile robots such as automated guided vehicles become increasingly important in industry as they can greatly increase efficiency. For their operation such robots must rely on wireless communication, typically realized by connecting them to an existing enterprise network. In this paper we motivate that such an approach is not always economically viable or might result in performance issues. Therefore we propose a flexible and configurable mixed architecture that leverages on mesh capabilities whenever appropriate. Through experiments on a wireless testbed for a variety of scenarios, we analyse the impact of roaming, mobility and traffic separation and demonstrate the potential of our approach
On Making Emerging Trusted Execution Environments Accessible to Developers
New types of Trusted Execution Environment (TEE) architectures like TrustLite
and Intel Software Guard Extensions (SGX) are emerging. They bring new features
that can lead to innovative security and privacy solutions. But each new TEE
environment comes with its own set of interfaces and programming paradigms,
thus raising the barrier for entry for developers who want to make use of these
TEEs. In this paper, we motivate the need for realizing standard TEE interfaces
on such emerging TEE architectures and show that this exercise is not
straightforward. We report on our on-going work in mapping GlobalPlatform
standard interfaces to TrustLite and SGX.Comment: Author's version of article to appear in 8th Internation Conference

The renaissance of the theatre of memory
Giulio Camillo (1480 - 1544) was as well-known in his era as Bill Gates is now. Just like Gates he cherished a vision of a universal Storage and Retrieval System, and just like Microsoft Windows, his ‘Theatre of the Memory’ was, despite constant revision, never completed. Camillo’s legendary Theatre of Memory remained only a fragment, its benefits only an option for the future. When it was finished, the user - so he predicted - would have access to the knowledge of the whole universe. On account of his promising invention, Camillo’s contemporaries called him ‘the divine’. For others, like Erasmus or the Parisian scholars, he was just a ‘quack’, but also this only shows that his reception was as strong as is the case with the computer gurus of our days. Still, Camillo was forgotten immediately after his death. No trace is left of his spectacular databank - except a short treatise which he dictated on his deathbed and which was formulated in the future tense: ‘L’Idea del Theatro’ (1550). ..
