PLOX: A Secure Serverless Framework for the Smart Home by Micheal Friesen A thesis presented to the University of Waterloo in fulfillment of the thesis requirement for the degree of Master of Mathematics in Computer Science Waterloo, Ontario, Canada, 2021 c Micheal Friesen 2021 Author's Declaration This thesis consists of material all of which I authored or co-authored: see Statement of Contributions included in the thesis. This is a true copy of the thesis, including any required final revisions, as accepted by my examiners. I understand that my thesis may be made electronically available to the public. ii Statement of Contributions This thesis is based upon three different conference submissions to NSDI 2019, OSDI 2021 and NDSS 2022. The attached submission is therefore in part co-authored by myself, Ryan Hancock, Ali Mashtizadeh, Omid Abari, and Yousra Aafer, all authors of the submissions sent to these conferences. The PLOX framework was designed together by myself and Ryan Hancock, under the su- pervision of both Ali Mashtizadeh and Omid Abari. PLOX was developed by both Ryan and I, with the source code and commit history available on the Reliable Computer Sys- tems instance of Phabricator. My development contributions to PLOX were focused on the manifest system, design and development of the protocol used between devices, development of the converted smart applications used in the evaluation and implementation/testing of the taint-based IFC system. I was also responsible for the implementations of Amazon IoT Greengrass, Azure IoT Edge and Home Assistant used to compare PLOX against other systems in the evalua- tion. -

Concurrent Programming Made Simple: the (R)Evolution of Transactional Memory
Concurrent Programming Made Simple: The (r)evolution of Transactional Memory Nuno Diegues∗1 and Torvald Riegely2 1INESC-ID, Lisbon, Portugal 2Red Hat October 1, 2013 ∗[email protected] [email protected] 1 1 Harnessing Concurrency Today, it is commonplace for developers to deal with concurrency in their applications. This reality has been driven by two ongoing revolutions in terms of hardware deployments. On one hand, processors have evolved to a multi- core paradigm in which computational power increases by increasing number of cores rather than by enhancing single thread performance. On the other hand, cloud computing has democratized the access to affordable large- scale distributed platforms. In both cases programmers are faced with a similar problem: if they want to scale out their applications, then they need to tackle the issue of how to synchronize access to data in face of ever growing concurrency levels. For many decades, programmers have been taught to rely on locking mechanisms or centralized components to manage concurrent accesses to data. However, the ongoing architectural trends towards massively parallel/large- scale systems have unveiled the limitations of traditional synchronization schemes — not only can they significantly limit the feasible parallelism, when there may exist tremendous untapped parallel potential; they also force to use intricate programming models that are prone to tricky concurrency bugs, which can be a conundrum to detect and fix. In fact, popular knowledge considers locking approaches simple to understand, but difficult to master. 2 Programming with Transactions To tackle this fundamental problem in modern software development, during recent years both industry and academia have started to adopt Transactional Memory (TM). -

The approach consists of a simulation model is delivering the necessary systems combination of a digital twin of the real building and its states as input signals for the rule-based control strategy. HVAC system, modelled as a physical Modelica model Thereafter, the calculated control signals are sent back to and the openHAB software package, for the the simulation model. In our approach this bi-directional implementation of correspondent building control data exchange takes place between a home automation strategies. For this purpose, openHAB and the Modelica software, the open Home Automation Bus (openHAB) model is bi-directional coupled in real-time. In this way, software platform (openHAB, 2019) and the Modelica new control strategies can be tested and improved under simulation tool Dymola in real-time within the local consideration of the dynamic system behavior in the network.

There is rapid interest growing in the use of smart, connected devices. The developing world market for smart technology is evolving to adopt and adapt to the interconnected world of devices leading to the Internet of Things (IoT) everywhere. This research paper presents the design, development, and deployment of a prototype for the secure wireless home automation system with OpenHAB 2. We employed the use of two (2) high-performance microcontrollers, namely, the Arduino Mega 2560, interfaced with a 16-channel relay, and Raspberry Pi Model B, running the OpenHAB software. The Raspberry Pi functioned as the server to develop a prototype of an automated smart home that is remotely controllable from both a web application and an Android mobile app. -
