The Mathematics of Diffie-Hellman Key Exchange | Infinite Series
 
13:33
Viewers like you help make PBS (Thank you 😃) . Support your local PBS Member Station here: https://to.pbs.org/donateinfi Symmetric keys are essential to encrypting messages. How can two people share the same key without someone else getting a hold of it? Upfront asymmetric encryption is one way, but another is Diffie-Hellman key exchange. This is part 3 in our Cryptography 101 series. Check out the playlist here for parts 1 & 2: https://www.youtube.com/watch?v=NOs34_-eREk&list=PLa6IE8XPP_gmVt-Q4ldHi56mYsBuOg2Qw Tweet at us! @pbsinfinite Facebook: facebook.com/pbsinfinite series Email us! pbsinfiniteseries [at] gmail [dot] com Previous Episode Topology vs. “a” Topology https://www.youtube.com/watch?v=tdOaMOcxY7U&t=13s Symmetric single-key encryption schemes have become the workhorses of secure communication for a good reason. They’re fast and practically bulletproof… once two parties like Alice and Bob have a single shared key in hand. And that’s the challenge -- they can’t use symmetric key encryption to share the original symmetric key, so how do they get started?

Since anything encrypted with a given key can only be decrypted with the same key, Alice and Bob can exchange secure messages once they agree on a key. But what if Alice and Bob are strangers who can only communicate over a channel monitored by eavesdroppers like Eve? How do they agree on a secret key in the first place?

19.4 Cryptographic protocol
 
06:59
Module19 – Cryptography, Section 19.4 – Cryptographic protocol. Cryptographic protocol applies cryptographic methods and describes how the algorithms should be used and some aspects are: – Key agreement or establishment – Entity authentication – Symmetric encryption and message authentication material construction – Secured application-level data transport – Non-repudiation methods – Secret sharing methods – Secure multi-party computation Crypto Protocols • Internet Key Exchange (IKE) • IPSec (Internet Protocol Security) • Kerberos • Off-the-Record Messaging (OTR) • Point to Point Protocol (PPP) • Signal Protocol • Transport Layer Security (TLS) • ZRTP (Z and Real-time Transport Protocol) TLS is a cryptographic protocol that is used to secure web (HTTP/HTTPS) connections. TLS is used in applications such as web browsing, email, Internet faxing, instant messaging, and voice-over-IP (VoIP). The 3 aspects of TLS are: • It has an entity authentication mechanism, based on the X.509 system. • A key setup phase, where a symmetric encryption key is formed by employing public-key cryptography. • An application-level data transport function. Cryptographic protocols can be verified formally to identify threats and done through below models: • Dolev–Yao model • Burrows–Abadi–Needham logic (BAN logic) • Protocol composition logic (PCL) • Strand space • Alice & Bob notation Projects and tools for Security protocol verification – AVISPA and AVANTSSAR – Casper / FDR compiler – CryptoVerif, ProVerif – Cryptographic Protocol Shapes Analyzer (CPSA) – Knowledge In Security protocolS (KISS) – Maude-NRL Protocol Analyzer (Maude-NPA) – Scyther – Tamarin Prover

Symmetry-Based Learning
 
01:36:36
Learning representations is arguably the central problem in machine learning, and symmetry group theory is a natural foundation for it. A symmetry of a classifier is a representation change that doesn't change the examples' classes. The goal of representation learning is to get rid of unimportant variations, making important ones easy to detect, and unimportant variations are symmetries of the target function. Exploiting symmetries reduces sample complexity, leads to new generalizations of classic learning algorithms, provides a new approach to deep learning, and is applicable with all types of machine learning. In this talk I will present three approaches to symmetry-based learning: (1) Exchangeable variable models are distributions that are invariant under permutations of subsets of the variables. They subsume existing tractable independence-based models and difficult cases like parity functions, and outperform SVMs and state-of-the-art probabilistic classifiers. (2) Deep symmetry networks generalize convolutional neural networks by tying parameters and pooling over an arbitrary symmetry group, not just the translation group. In preliminary experiments, they outperformed convnets on a digit recognition task. (3) Symmetry-based semantic parsing defines a symmetry of a sentence as a syntactic transformation that preserves its meaning. The meaning of a sentence is thus its orbit under the semantic symmetry group of the language. This allows us to map sentences to their meanings without pre-defining a formal meaning representation or requiring labeled data in the form of sentence-formal meaning pairs, and achieved promising results in a paraphrase detection problem.

Why not squares? Or asymmetrical blobby shapes? In 36 B.C., the Roman scholar Marcus Terentius Varro wrote about two of the leading theories of the day. First: bees have six legs, so they must obviously prefer six-sided shapes. But that charming piece of numerology did not fool the geometers of day. They provided a second theory: Hexagons are the most efficient shape. Bees use wax to build the honeycombs -- and producing that wax expends bee energy. The ideal honeycomb structure is one that minimizes the amount of wax needed, while maximizing storage -- and the hexagonal structure does this best.

Public Key Cryptography: Secrecy in Public - Professor Raymond Flood
 
01:05:04
For centuries massive intellectual effort has gone into methods of ensuring secure communication, because of its importance in diplomatic, commercial and military affairs. Up until recently these methods have relied on the exchange of a secret key or protocol between correspondents. Now, however, a new approach based on mathematics, called public key cryptography, is used and this underlies much of modern commerce and how you pay over the internet. The transcript and downloadable versions of the lecture are available from the Gresham College website: http://www.gresham.ac.uk/lectures-and-events/public-key-cryptography-secrecy-in-public Gresham College has been giving free public lectures since 1597. This tradition continues today with all of our five or so public lectures a week being made available for free download from our website. There are currently over 1,500 lectures free to access or download from the website.

Language based techniques for cryptography and privacy
 
01:03:11
UCL Computer Science Distinguished Lecture A common theme in program verification is establishing relationships between two runs of the same program or of different programs. Such relationships can be proved by semantical means, or with syntactic methods such as relational program logics and product constructions. Gilles shall present an overview of these methods and their applications to provable security, differential privacy, and secure implementations. Gilles Barthe is a research professor at the IMDEA Software Institute. His research interests include logic, formal verification, programming languages, and security. His current work focuses on verification and synthesis methods for cryptography and differential privacy. He is a member of the editorial boards of the Journal of Automated Reasoning and Journal of Computer Security. He received a Ph.D. in Mathematics from the University of Manchester, UK, in 1993, and an Habilitation à diriger les recherches in Computer Science from the University of Nice, France, in 2004.

Frank Pasquale on Privacy, Secrecy, and Corporate Data Flows
 
01:20:00
Every day, corporations collect data on our personal behavior and use algorithms to make judgments that shape our lives and our communities. Often, those decisions are made in secrecy and founded on private or false information. Frank Pasquale joins Tech for Good at the Claremont Colleges for a talk on corporations and the flow of personal data. Frank Pasquale is an expert on the law of artificial intelligence, algorithms, and machine learning. He has been recognized as one of the ten most cited scholars in health law in the United States. His book, The Black Box Society: The Secret Algorithms that Control Money and Information, develops a social theory of reputation, search, and finance, and offers pragmatic reforms to improve the information economy. The Black Box Society has been reviewed in Science and Nature, and published in Chinese, French, Korean, and Serbian translations. Pasquale has been recognized as one of the leaders of a global movement for algorithmic accountability and co-organized one of the leading conferences on the topic in 2016. In media and communication studies, he has developed a comprehensive legal analysis of barriers to (and opportunities for) regulation of internet platforms. He keynoted the German Re:Publica conference in 2017 with a talk on the automated public sphere, and the Canadian Data/Power conference in 2017 with a talk on how law and policy may shape the future of journalism. In privacy law and surveillance, his work is among the leading research on regulation of algorithmic ranking, scoring, and sorting systems, including credit scoring and threat scoring.

SAGE Ocean Speaker Series #4: Digital Power with Carl Miller
 
01:02:13
Carl Miller, author of The Death of the Gods: The New Global Power Grab and Research Director of the Centre for the Analysis of Social Media (CASM) at Demos delivers a fascinating talk about the new centres of power and control in the twenty-first century. Pre order the book now: http://bit.ly/DeathoftheGods Background The old gods are dying. Giant corporations collapse overnight. Newspapers are being swallowed. Stock prices plummet with a tweet. Governments are losing control. The old familiarities are tumbling down and a strange new social order is rising in their place. More crime now happens online than offline. Facebook has grown bigger than any state, bots battle elections, technologists have re-invented democracy and information wars are breaking out around us. New mines produce crypto-currencies, coders write policy, and algorithms shape our lives in more ways than we can imagine. What is going on? For centuries, writers and thinkers have used power as a prism through which to view and understand the world at moments of seismic change. In this talk, we'll hear Carl discuss his journey to find the reality of power today. From a cyber-crime raid in suburbia to the engine rooms of Silicon Valley, and from the digital soldiers of Berkshire to the hackers of Las Vegas, he will explain how power – the most important currency of all – is being transformed, fought over, won and lost. As power escapes from its old bonds, he shows us where it has gone, the shape it now takes and how it touches each of our lives. The SAGE Ocean Speaker Series was launched earlier this year to explore the intersection of social science, big data and technology. https://ocean.sagepub.com/ Call for Speakers! If you're interested in speaking at one of our future events and engaging with the social science, publishing and tech communities in London, we'd love to hear from you. Please send us a message and we'll get back to you with more information. https://ocean.sagepub.com/contact

These networks might represent Facebook friendships, or help us understand the spread of disease. This episode focuses on one model of a social network that encodes whether relationships are positive or negative -- in other words, if they’re friendly or hostile -- and the notion of structural balance.
