DEF CON 23 - Eijah - Crypto for Hackers
 
55:52
Hacking is hard. It takes passion, dedication, and an unwavering attention to detail. Hacking requires a breadth of knowledge spread across many domains. We need to have experience with different platforms, operating systems, software packages, tools, programming languages, and technology trends. Being overly deficient in any one of these areas can add hours to our hack, or even worse, bring us total failure. And while all of these things are important for a well-rounded hacker, one of the key areas that is often overlooked is cryptography. In an era dominated by security breaches, an understanding of encryption and hashing algorithms provides a tremendous advantage. We can better hone our attack vectors, especially when looking for security holes. A few years ago I released the first Blu-Ray device key, AA856A1BA814AB99FFDEBA6AEFBE1C04, by exploiting a vulnerability in an implementation of the AACS protocol. As hacks go, it was a simple one. But it was the knowledge of crypto that made it all possible. This presentation is an overview of the most common crypto routines helpful to hackers. We'll review the strengths and weaknesses of each algorithm, which ones to embrace, and which ones to avoid. You'll get C++ code examples, high-level wrapper classes, and an open-source library that implements all the algorithms. We'll even talk about creative ways to merge algorithms to further increase entropy and key strength. If you've ever wanted to learn how crypto can give you an advantage as a hacker, then this talk is for you. With this information you'll be able to maximize your hacks and better protect your personal data. Speaker Bio: Eijah is the founder of demonsaw, a secure and anonymous content sharing platform, and a Senior Programmer at a world-renowned game development studio. He has over 15 years of software development and IT Security experience. His career has covered a broad range of Internet and mid-range technologies, core security, and system architecture. Eijah has been a faculty member at multiple colleges, has spoken about security and development at conferences, and holds a master’s degree in Computer Science. Eijah is an active member of the hacking community and is an avid proponent of Internet freedom.

The Blockchain and Us (2017)
 
31:27
A film by Manuel Stagars http://www.blockchain-documentary.com For more interviews about the brave new world of blockchain technology and cryptocurrencies, see Manuel's podcast: http://www.theblockchainandus.com. In 2008, Satoshi Nakamoto invented bitcoin and the blockchain. For the first time in history, his invention made it possible to send money around the globe without banks, governments or any other intermediaries. The concept of the blockchain isn’t very intuitive. But still, many people believe it is a game changer. Economist and filmmaker Manuel Stagars portrays this exciting technology in interviews with software developers, cryptologists, researchers, entrepreneurs, consultants, VCs, authors, politicians, and futurists from the United States, Canada, Switzerland, the UK, and Australia. The Blockchain and Us is no explainer video of the technology. It gives a view on the topic, makes it accessible and starts a conversation about its potential wider implications in a non-technical way. The film deliberately poses more questions than it answers.

CppCon 2018: “Secure Coding Best Practices: Your First Line Is The Last Line Of Defense (1 of 2)”
 
59:56
http://CppCon.org Matthew Butler “Secure Coding Best Practices: Your First Line Is The Last Line Of Defense (part 1 of 2)” — Presentation Slides, PDFs, Source Code and other presenter materials are available at: https://github.com/CppCon/CppCon2018 — Computer systems are under siege 24 hours a day, day in and day out. The critical security infrastructure designed to protect those systems, won't: * Perimeter security won't protect you. * Network analytics won't protect you. * Virus scanners won't protect you. * Even the users who should know better than to click on that too-good-to-be-true offer won't protect you. The other side has the best security hardware and software systems other people's money can buy and they have all the time in the world to find creative ways to defeat them. Meltdown and Spectre are prime examples of security vulnerabilities that have lurked dormant for decades. Or have they? If your systems are in any way connected to the outside world, the other side will get inside the wire on you. Know that going in. Whether you write applications, libraries or work in kernel code, the line of code you write today may very well be the vulnerability someone else finds tomorrow. By nature every code base contains hundreds of attack surfaces and it only takes one serious vulnerability to compromise your system. While Modern C++ is designed to be secure, the ways we use it often aren't. In part one of this talk we'll see: * How hackers think and how they identify weaknesses in our systems. * How to identify hidden attack surfaces, attack vectors and vulnerabilities in critical systems. * Where the most common vulnerabilities in Modern and classic C++ are and how to avoid them. * Why avoiding parts of the language doesn't help. * Where we can trade off security for performance. At the end of part one, we'll do a walkthrough of a classic buffer overflow exploit to see how it works and what we've added to the operating systems and compilers to protect against them. Then we'll use it live to run a privilege escalation exploit and gain admin access on a system. In part two, we'll see: * Why common guidelines and static analysis tools often fail to find vulnerabilities. * How to use Threat Modeling to analyze complex systems and build security into our systems at design time. * How to use Trust Boundaries to protect critical infrastructure. * Why open source and third-party libraries are fast becoming hidden liabilities in our software and how to protect ourselves against their vulnerabilities. * What the best practices for protecting our code from attack are. At the end of part two, we'll do a walkthrough of an exploit that can be successful today in spite of the safe guards built into our operating systems and compilers. Then, as before, we'll use it live to penetrate a system. The critical security infrastructure designed to protect your systems is largely out of your control. The one thing you can control is the next line of code you write. This talk is for anyone that uses C++ or Modern C++ for kernel, applications or libraries that run in the real-world and that face real-world attacks. In today's world, that's all of us. — Matthew Butler Matthew Butler has spent the last three decades as a systems architect and software engineer developing systems for network security, law enforcement and the military. He primarily works in signals intelligence using C, C++ and Modern C++ to build systems running on hardware platforms ranging from embedded micro-controllers to FPGAs to large-scale airborne platforms. Much of his experience has come in either building systems that defend against attackers or building highly sensitive systems that are targets. He is actively involved in the C++ community and is on various planning committees for C++Now and CppCon as well as being a speaker at both. Over the past thirty years, he has learned the harsh lessons on how we often write systems that fail, not because they don't scale, but because they aren't designed to be secure. — Videos Filmed & Edited by Bash Films: http://www.BashFilms.com

"Quantum Computing and the Entanglement Frontier" John Preskill, CalTech
 
01:26:48
The quantum laws governing atoms and other tiny objects seem to defy common sense, and information encoded in quantum systems has weird properties that baffle our feeble human minds. John Preskill will explain why he loves quantum entanglement, the elusive feature making quantum information fundamentally different from information in the macroscopic world. By exploiting quantum entanglement, quantum computers should be able to solve otherwise intractable problems, with far-reaching applications to cryptology, materials, and fundamental physical science. Preskill is less weird than a quantum computer, and easier to understand.

Encryption Theory: The evolution of humor as an honest signal
 
55:29
10/18/2010 Thomas Flamson - UCLA Department of Anthropology "Encryption Theory: The evolution of humor as an honest signal" The Encryption Theory of Humor proposes that humor evolved as a means of signaling similarity in locally variable personal features in order to facilitate assortment with the most compatible peers within the local group. It claims that a necessary component of humorous production is the presence of multiple, divergent understandings of speaker meaning, some of which are dependent on access to implicit information. Because of this dependence, only those listeners with access to this background knowledge can "decrypt" the implicit understandings, which further entails the inference that the speaker shares that access. This provides a channel for the honest signaling of personal features, which enables within-group assortment for compatible long-term interaction partners such as friends or mates. This talk will present a range of data supporting various aspects of this hypothesis, obtained both through online studies with literate Western participants, and ethnographic observation and studies conducted in rural northeastern Brazil. It will be shown that (a) prior knowledge interacts with information provisioning to impact individual humor preferences, (b) these preferences reflect closeness in real-world social networks, and (c) evaluations of the sense of humor of other individuals also reflect social closeness. These findings support the hypothesis that humor evolved as a subjective, interdependent signaling system for compatibility matching, and not simply as an index of objectively-evaluated traits, such as intelligence.

28c3: Time is on my Side
 
01:01:05
Download high quality version: http://bit.ly/voKTiV Description: http://events.ccc.de/congress/2011/Fahrplan/events/4640.en.html Sebastian Schinzel: Time is on my Side Exploiting Timing Side Channel Vulnerabilities on the Web Timing side channel attacks are non-intrusive attacks that are still widely ignored in day-to-day penetration testing, although they allow attackers to breach the confidentiality of sensitive information. The reason for this is, that timing attacks are still widely considered to be theoretical. In this talk, I present a toolkit for performing practical timing side channel attacks and showcase several timing attacks against real-world systems. Timing side channels are vulnerabilities in software applications that leak sensitive information about secret values such as cryptographic keys. They differ from common intrusive vulnerabilities such as Buffer Overflows or SQL-Injection because the attacker sends normally looking requests to the server and infers secret information just from the time it took to process the request. In academia, timing side channel attacks are well researched, especially against cryptographic hardware, but in day-to-day penetration testing, they are still widely ignored. One reason for this is that the timing differences are often small compared to the jitter introduced in networked environments. This makes practical timing side channel attacks challenging, because the actual timing differences blend with the jitter. In this talk, I will present methods and tools to accurately measure response times despite the jitter in networked environments. I will introduce a programming library that enables penetration testers to measure accurate response times of requests send over networks. Furthermore, I will describe algorithms and statistical filters to reduce the jitter from measurements. For this, I will introduce a reporting tool that takes a dataset with network measurements as input, automatically applies the algorithms and filters, and produces a report with the results. This report enables even novice penetration testers to analyze a response time dataset for timing side channel vulnerabilities. In the end, I will show that timing side channels are practical by showing several attacks. First, I show how to determine if a given user name is an administrative user in a productive installation of the popular CMS Typo3. Second, I show how to determine how many pictures are hidden in a private album of an online gallery. Third, I show how to perform an adaptive chosen cipher text attack against implementations of the XML Encryption standard. This attack allows to decrypt any Web Service message whose body was encrypted using XML Encryption only by measuring the response time of the Web Service.

APL Comp. Science & Eng. Seminar Series: On-line patching & security / Michael Hicks
 
57:49
APL Computer Science and Engineering Seminar Series "On-line patching for better security, and other security challenges" Michael W. Hicks Professor Michael W. Hicks' research focuses on developing programming language technology to help programmers build software that is available, reliable, and secure. In this talk he will present an overview of his interests and general approach, details on one research direction, and highlights of the Maryland Cybersecurity Center (MC2). The first half of the talk describes his recent research on dynamic software updating (DSU). For systems that require (or would prefer) continuous operation, software updates to fix bugs and vulnerabilities or upgrade functionality create a problem, as updates normally require a shutdown and restart. DSU addresses this problem by allowing updates to be applied without shutting the system down. Dr. Hicks has recently developed a system called Kitsune for supporting DSU in C programs. Kitsune is flexible, efficient, and relatively easy to use: it has been used to support more than 40 release-level updates to six popular C server programs while requiring few code changes, and imposing no overhead to normal execution. The second portion of the talk describes the Maryland Cybersecurity Center and the research and education activities taking place there, which cover topics including system security, software security, resilient distributed systems, game theory, applied cryptography, network forensics, security economics, and supply chain security, among other topics. Bio: Michael W. Hicks is professor in the Computer Science department and UMIACS at the University of Maryland, College Park, and is the Director of the Maryland Cybersecurity Center (MC2). His research focuses on using programming languages and analyses to improve the security, reliability, and availability of software. Noteworthy among his research accomplishments is the development of analysis and compilation tools for enabling software to be safely updated while it runs. He has explored the design of new programming languages and analysis tools for automatically discovering or remediating software flaws and security vulnerabilities. He has recently been exploring new approaches to privacy preserving computation, and means to debug programs more effectively.

ICERM Public Lecture: Sleeping Beauty and Other Probability Conundrums
 
01:07:29
Probability puzzles are notoriously tricky, and the best ones continue to intrigue the public and confound philosophers. In his talk, Dr. Peter Winkler examines some of these questions and tries to determine whether they uncover real problems with the foundations of probability theory, or just challenge our flawed human intuition. Peter Winkler is William Morrill Professor of Mathematics and Computer Science at Dartmouth College. He is the author of more than 150 research papers and holds a dozen patents in marine navigation, cryptolography, holography, gaming, optical networking, and distributed computing. His research is primarily in combinatorics, probability, and the theory of computing, with forays into statistical physics. He is a winner of the Mathematical Association of America's Lester R. Ford and David P. Robbins prizes. Dr. Winkler has also written two collections of mathematical puzzles, a book on cryptology in the game of bridge, and a portfolio of compositions for ragtime piano.

Coding theory
 
19:12
Coding theory is the study of the properties of codes and their fitness for a specific application. Codes are used for data compression, cryptography, error-correction and more recently also for network coding. Codes are studied by various scientific disciplines—such as information theory, electrical engineering, mathematics, linguistics, and computer science—for the purpose of designing efficient and reliable data transmission methods. This typically involves the removal of redundancy and the correction of errors in the transmitted data. This video is targeted to blind users.

Telecommunication Engineering, Dayananda Sagar College of Engineering, Bangalore-560078, karnataka.India 2 Pune Institute of Computer Technology Pune-411043,Maharastra, India 3 Dept. Electronics and Communication Engineering, Dayananda Sagar College of Engineering, Bangalore-560078, karnataka., [email protected] [email protected] [email protected] ABSTRACT Video compression method such as H.264/AVC often causes to huge computing complexity at the encoder that is generally implemented in various multimedia applications. In view of this an article on selective video encryption framework based upon Advanced Encryption Standard (AES) is suggested for prioritized frames of H.264/AVC to improve the multimedia security while maintaining the low complexity at the encoder. The experimental result demonstrates that the recommended technique contributes significant security to video streams while maintaining the original video compression efficiency and compression ratio. Moreover, the proposed scheme provides a good tradeoff between encryption robustness, flexibility, and real-time processing.

Discrete mathematics
 
20:49
Discrete mathematics is the study of mathematical structures that are fundamentally discrete rather than continuous. In contrast to real numbers that have the property of varying "smoothly", the objects studied in discrete mathematics – such as integers, graphs, and statements in logic – do not vary smoothly in this way, but have distinct, separated values. Discrete mathematics therefore excludes topics in "continuous mathematics" such as calculus and analysis. Discrete objects can often be enumerated by integers. More formally, discrete mathematics has been characterized as the branch of mathematics dealing with countable sets (sets that have the same cardinality as subsets of the natural numbers, including rational numbers but not real numbers). However, there is no exact definition of the term "discrete mathematics." Indeed, discrete mathematics is described less by what is included than by what is excluded: continuously varying quantities and related notions. The set of objects studied in discrete mathematics can be finite or infinite. The term finite mathematics is sometimes applied to parts of the field of discrete mathematics that deals with finite sets, particularly those areas relevant to business.

The entire global banking system is dependent on strong and secure encryption to allow secure digital financial transactions. Digital financial capabilities have allowed modern economies to flourish in the digital age. Without trust in the security of these systems, the global economy would diminish. As technology evolves the security implications related to safeguarding technological infrastructure evolve simultaneously, presenting major challenges to current legal and regulatory structures. Against this backdrop, every day seems to bring new horror stories of cyber-security breaches, each more shocking than the last. Calls for enhanced cybersecurity measures including strong encryption are matched by law enforcements calls for access to the encrypted data. Law enforcement officials claim that terrorists and criminals hide behind the anonymity created by strong encryption while cryptologists and cyber security experts demand that back doors create vulnerabilities that criminals and hostile governments will certainly exploit. Can solutions be engineered that will enhance security and protect privacy without hampering law enforcement’s legitimate needs? This panel examines these and other important questions about the future of cybersecurity in light of recent headlines. |
ALAN TURING - WikiVidi Documentary
 
15:43
Alan Mathison Turing was an English computer scientist, mathematician, logician, cryptanalyst, philosopher, and theoretical biologist. Turing was highly influential in the development of theoretical computer science, providing a formalisation of the concepts of algorithm and computation with the Turing machine, which can be considered a model of a general purpose computer. Turing is widely considered to be the father of theoretical computer science and artificial intelligence. During the Second World War, Turing worked for the Government Code and Cypher School at Bletchley Park, Britain's codebreaking centre that produced Ultra intelligence. For a time he led Hut 8, the section which was responsible for German naval cryptanalysis. Here he devised a number of techniques for speeding the breaking of German ciphers, including improvements to the pre-war Polish bombe method, an electromechanical machine that could find settings for the Enigma machine. Turing played a pivotal role in c... http://www.wikividi.com ____________________________________ Shortcuts to chapters: 00:03:08 Family 00:05:00 School 00:06:44 Christopher Morcom 00:08:33 University and work on computability 00:11:27 Career and research ____________________________________ Copyright WikiVidi.

Written language only began at around 3200 BC, but spoken language has existed long ago. Learning by listening is a great way to: - increases imagination and understanding - improves your listening skills - improves your own spoken accent - learn while on the move - reduce eye strain Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone.
