ABS 2014 - The Growth of Android in Embedded SystemsBenjamin Zores
The document discusses the growth of Android in embedded systems. It provides an overview of Android's history and architecture. While Android has brought Linux to many devices, its proprietary development model and design flaws mean it is not optimal for all embedded use cases. Specifically, it can be a burden for manufacturers due to fragmentation, proprietary drivers, and high hardware requirements. However, Android remains attractive for its application framework, time-to-market advantages, and focus on the user experience rather than low-level software.
Droidcon 2013 france - The Growth of Android in Embedded SystemsBenjamin Zores
1) Android was originally developed by Android Inc. in the 2000s and was purchased by Google in 2005. It was revamped to be based on Linux and the first Android smartphone was released in 2008.
2) Android is appealing for some embedded systems due to its standardized application framework and aggressive time-to-market. However, it also has some downsides for performance-critical systems due to its Java-based design and proprietary changes from vanilla Linux.
3) While Android has brought Linux to many consumer devices, it has also slowed down some innovation and standardization in embedded systems. Linux remains a better choice for embedded devices not focused on apps and with high performance needs.

Android is a software stack that includes an operating system, middleware, and key applications. It uses a modified version of the Linux kernel and other open source software. The Android runtime, known as Dalvik and later ART, allows apps to be run in a virtual machine using the Java programming language. Android apps are composed of components like activities, services, content providers and broadcast receivers that can interact and run either in the foreground or background. The Android SDK provides libraries for building apps that have access to the device's capabilities like sensors, internet connectivity and more.

With Android activations reaching a million devices per day, it is no surprise that security threats against our favorite mobile platform have been on the rise.
In this session, you will learn all about Android's security model, including application isolation (sandboxing) and provenance (signing), its permission system and enforcement, data protection features and encryption, as well as enterprise device administration.
Together, we will dig into Android's own internals to see how its security model is applied through the entire Android stack - from the Linux kernel, to the native layers, to the Application Framework services, and to the applications themselves.
Finally, you’ll learn about some of the weaknesses in the Android's model (including rooting, tap-jacking, malware, social-engineering) as well as what can be done to mitigate those threats, such as SE-Linux, memory protection, anti-malware, firewall, and developer best practices.
By the end of this session you will have a better understanding of what it takes to make Android a more trusted component of our personal and professional lives.

Several methods are proposed for manipulating the current directory to execute an exploit DLL from a remote location, including browser UI redressing, macros, MHT files, archives, and multistage attacks. The document concludes DLL hijacking is well-suited for targeted attacks but not mass attacks due to reliance on user interaction and 0-days.
This document discusses techniques for exploiting DLL hijacking vulnerabilities remotely through user interaction. It argues that DLL hijacking is still a viable attack vector despite protections like DEP and ASLR. It proposes manipulating the current directory to execute exploits and hiding DLLs in archives, email attachments, and browser redressing to trigger exploits without appearing suspicious. While not suitable for mass attacks, it concludes DLL hijacking enables rapid targeted attacks by abusing existing vulnerabilities.
The document discusses the history and development of the Android operating system, describing how it was created by Android Inc. and later acquired by Google, and outlines some of the key aspects of the Android platform including its open source nature, hardware requirements, software architecture using Linux and Java, and security features.

The document discusses various machine learning clustering algorithms like K-means clustering, DBSCAN, and EM clustering. It also discusses neural network architectures like LSTM, bi-LSTM, and convolutional neural networks. Finally, it presents results from evaluating different chatbot models on various metrics like validation score.
The document discusses challenges with using reinforcement learning for robotics. While simulations allow fast training of agents, there is often a "reality gap" when transferring learning to real robots. Other approaches like imitation learning and self-supervised learning can be safer alternatives that don't require trial-and-error. To better apply reinforcement learning, robots may need model-based approaches that learn forward models of the world, as well as techniques like active localization that allow robots to gather targeted information through interactive perception. Closing the reality gap will require finding ways to better match simulations to reality or allow robots to learn from real-world experiences.

Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...Alex Pruden
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.
