CppCon 2018: Chandler Carruth “Spectre: Secrets, Side-Channels, Sandboxes, and Security”
 
01:27:35
http://CppCon.org — Presentation Slides, PDFs, Source Code and other presenter materials are available at: https://github.com/CppCon/CppCon2018 — The discovery of speculative execution side-channel attacks (called "Spectre") fundamentally changes the security model of every modern superscalar microprocessor. Extracting secret data (credit cards, cryptographic keys) through side-channels is not new and has challenged the cryptographic community for decades. Despite this, the industry has often been complacent in our response, viewing these attacks as impacting a tiny amount of code and being nearly impossible to weaponize. But speculative execution attack techniques have fundamentally altered the ease and applicability of side-channels, making them a serious threat to computer security. Responding to these issues has impacted CPU design, compiler design, library design, sandbox techniques and even the C++ programming language and standard. This talk will explain how these kinds of attacks work at a high level and provide a clear set of terminology to describe these classes of vulnerabilities and attacks. It will show how the different variants work at the low level of modern hardware to give a detailed and precise understanding of the mechanics involved on CPUs today. It will also provide guidance about what makes applications and services vulnerable and how to analyze your software to understand the degree of its exposure. It will include an overview of the numerous different mitigation techniques available, how to deploy them, and what tradeoffs come with them. Some of these mitigations will be covered in detail: how they work at a hardware level, where they don't work, and what attack vectors remain. Finally, the talk will show how traditional side-channel risks are made substantially easier to exploit due to speculative execution. This will cover how cryptographic and other libraries dealing in high-value secrets need to be adapted to correctly defend against these attacks. Further, it will introduce general problems of sandboxing untrusted code from secret data and the current best techniques in those circumstances. This talk will be accessible to most C and C++ programmers. No deep background on CPUs, assembly, hardware instructions, Spectre, side-channels, or security is needed. — Chandler Carruth, Google Software Engineer Chandler Carruth leads the Clang team at Google, building better diagnostics, tools, and more.

"OpenScore: Open-sourcing sheet music" presented at FOSDEM 2019 in Brussels, Belgium https://fosdem.org/2019/schedule/event/openscore_sheet_music/ This presentation describes our method for digitising public domain sheet music, and shares details of some of the key challenges and hurdles we have had to overcome since the launch of our Kickstarter campaign in 2017. Follow us for updates when new scores are released! https://openscore.cc/ https://twitter.com/OpenScore https://www.facebook.com/OpenScore.cc/ OpenScore is a crowdsourced initiative to transcribe the world's public domain sheet music into an open source, digital format. This brings music notation into the 21st Century, enabling its convenient use on devices such as phones, tablets and computers. OpenScore extends the principles of open source to apply not only to software, but also to the content produced by the software, thereby opening up a new avenue of funding for open source software development.

Crypto Defenses for Real-World System Threats - Kenn White - Ann Arbor
 
01:36:58
Modern encryption techniques provide several important security properties, well known to most practitioners. Or are they? What are in fact the guarantees of, say, HTTPS TLS cipher suites using authenticated encryption, IPSec vs. SSL VPNs, Property Preserving Encryption, or token vaults? We live in an era of embedded Hardware Security Modules that cost less than $1 in volume, and countless options now exist for encrypting streaming network data, files, volumes, and even entire databases. Let's take a deep dive into the edge of developed practice to discuss real-world threat scenarios to public cloud and IoT data, and look closely at how we can address specific technical risks with our current encryption toolkits. Advanced math not required. Bio: Kenneth White is a security researcher whose work focuses on networks and global systems. He is co-director of the Open Crypto Audit Project (OCAP), currently managing a large-scale audit of OpenSSL on behalf of the Linux Foundation's Core Infrastructure Initiative. Previously, White was Principal Scientist at Washington DC-based Social & Scientific Systems where he led the engineering team that designed and ran global operations and security for the largest clinical trial network in the world, with research centers in over 100 countries. White co-founded CBX Group which provides security services to major organizations including World Health, UNICEF, Doctors without Borders, the US State Department, and BAO Systems. Together with Matthew Green, White co-founded the TrueCrypt audit project, a community-driven initiative to conduct the first comprehensive cryptanalysis and public security audit of the widely used TrueCrypt encryption software. White holds a Masters from Harvard and is a PhD candidate in neuroscience and cognitive science, with applied research in real-time classification and machine learning. His work on network security and forensics and been cited by media including the Wall Street Journal, Forbes, Reuters, Wired and Nature. White is a technical reviewer for the Software Engineering Institute, and publishes and speaks frequently on computational modeling, security engineering, and trust. He tweets @kennwhite.
