Why cryptography and information Security course
 
05:08
www.hiteshChoudhary.com www.newdemy.com Cryptography What is cryptography? Cryptography (or cryptology; from Greek κρυπτός, "hidden, secret"; and γράφειν, graphein, "writing", or -λογία, -logia, "study", respectively) is the practice and study of techniques for secure communication in the presence of third parties (called adversaries).More generally, it is about constructing and analyzing protocols that overcome the influence of adversaries and which are related to various aspects in information security such as data confidentiality, data integrity, authentication, and non-repudiation. Modern cryptography intersects the disciplines of mathematics, computer science, and electrical engineering. Applications of cryptography include ATM cards, computer passwords, and electronic commerce. Yeah, I know that you have read the above lines many times. These are perfectly true jargons. It’s just something like our brain is made of 80% of water, technically true but it doesn’t explain things much. When I tried to study Cryptography, it was tough. When anyone wants to learn HTML, he can find a lots of resources on internet but when things come to Cryptography you need to buy a lots of books and watch a lots of youtube videos which contains an annoying background music. A lots of blog are also helpful but all are fragmented. So, I decided that it is a good time to put Cryptography course. The course will be beginners friendly and will teach you a lot of things about Information Security. This series is not meant for 2 communities of people over the internet. 1. Not bothered about Computer Security 2. True Computer professional [Advanced programmers and crypto masters] The category one does not fit into any computer security course as information security comes at very last in their priority list. Hence, most of the time they are the practice playgrounds for most of the hackers. The category two has moved into the immense knowledge of information security. And they know all the stuff or most of the present stuff about it. So, they will feel bore in this series because they are the inventor of most of the stuff. Rest of the people are going to love this cryptography online video series. The candidates for which I am looking to take this cryptography course are: 1. University Students 2. Hackers a. Fretos : The freshers b. Practos: The practical ones University Students will be interested in this course as most of the Universities have curriculum of Cryptography. The second category is of hackers but I have divided them into 2 major categories. First one is Fretos, these are fresher in information security and are trying to learn stuff. It is a good time for them to start this series because you will understand terms like MITM, RSA, MD5 and DSA. Second category is hackers who have learned most of the things practically. Personally, I am very impressed that you have gained so much of knowledge. You might have knowledge about hacking into various accounts and systems or even knowledge of creating exploits. But ask a simple question to yourself, you are a pro in hacking skills but have no idea about RSA or Block ciphers. You know to break WEP in wireless but no idea of WEP encryption or cryptic flaw in algorithm. I hope that you have got my point. So, let’s get started.

Will Quantum Computers break encryption?
 
15:45
How do you secure messages over the internet? How do quantum computers break it? How do you fix it? Why don't you watch the video to find out? Why does this description have so many questions? Why are you still reading? What is the meaning of life? Facebook: https://www.facebook.com/frameofessence Twitter: https://twitter.com/frameofessence YouTube: https://www.youtube.com/user/frameofessence CLARIFICATIONS: You don't actually need a quantum computer to do quantum-safe encryption. As briefly mentioned at 7:04 , there are encryption schemes that can be run on regular computers that can't be broken by quantum computers. CORRECTIONS: [2:18] Technically, you can use any key to encrypt or decrypt whatever you want. But there's a specific way to use them that's useful, which is what's shown in the video. [5:36] In RSA, depending on exactly what you mean by "private key", neither key is actually derivable from the other. When they are created, they are generated together from a common base (not just the public key from the private key). But typically, the file that stores the "private key" actually contains a bit more information than just the private key. For example, in PKCS #1 RSA private key format ( https://tools.ietf.org/html/rfc3447#appendix-A.1.2 ), the file technically contains the entire public key too. So in short, you technically can't get the public key from the private key or vice versa, but the file that contains the private key can hold more than just the private key alone, making it possible to retrieve the public key from it.

Soaring, Cryptography and Nuclear Weapons
 
55:47
Google Tech Talk May 7, 2009 ABSTRACT Presented by Martin Hellman Nuclear weapons are the elephant in the room that almost no one talks about. This presentation therefore approaches the subject from the much less threatening -- actually downright attractive -- perspective of soaring. Risk analysis is the glue that ties the two subjects together, while my experience in developing public key cryptography provides an important lesson on the positive side. Related links: http://nuclearrisk.org/soaring_article.php is an article that is closely related to the talk. Another link of interest is http://nuclearrisk.org/paper.pdf. Martin Hellman is Professor Emeritus at Stanford University and co-inventor of public key cryptography.

Public Key Infrastructure Fundamentals - Bart Preneel
 
01:31:53
The function of a public key infrastructure (PKI) is to ensure secure delivery and management of public keys. Alternative trust models lead to different key architectures. Public keys are published by means of digitally signed certificates. A private key may be compromised, in which case the certificate containing the corresponding public key must be revoked. Many revocation methods are in current use. Publication of Certificate Revocation Lists (CRLs) and checking with an Online Certificate Status Protocol (OCSP) responder are best established. Learning objectives + learn the components of a public key infrastructure. + understand key delivery and management mechanisms. A lecture by Bart Preneel at SecAppDev 2013 in Leuven, Belgium. Professor Bart Preneel of KU Leuven heads the COSIC (COmputer Security and Industrial Cryptography) research group. His main research area is information security with a focus on cryptographic algorithms and protocols as well as their applications to both computer and network security, and mobile communications. He teaches cryptology, network security and coding theory at the K.U.Leuven and was visiting professor at the Ruhr Universitaet Bochum (Germany), the T.U.Graz (Austria), the University of Bergen (Norway), and the Universiteit Gent (Belgium). In '93-'94 he was a research fellow at the University of California at Berkeley. He has taught intensive courses around the world. He undertakes industrial consulting (Mastercard International, S.W.I.F.T., Proton World International,...), and participates in the work of ISO/IEC JTC1/SC27/WG2. Professor Preneel is Vice President of the International Association for Cryptologic Research (IACR) and co-founder and chairman of LSEC vzw (Leuven Security Excellence Consortium).

PWLSF - 6/2016 - Kiran Bhattaram on A Mathematical Theory of Communication
 
01:10:09
Talks given June 23, 2016 at Stripe HQ ===== Mini Lukasz Jagiello on “pASSWORD tYPOS and How to Correct Them Securely” (https://www.cs.cornell.edu/~rahul/papers/pwtypos.pdf) Lukasz tells us: “typo-tolerant password authentication for arbitrary user-selected passwords” sounds like a really bad security joke but if we combine that with metrics where almost 10% of failed login attempts fail due to a handful of simple, easily correctable typos, such as capitalization errors. Authors proves it is possible to improve user experience with really low impact on security. I really enjoy this paper because it’s not a standard security approach and in many places it’s a reasonable tradeoff between security and UX. Lukasz's Bio Lukasz Jagiello is an operations engineer at Wikia where he is hard working on saying NO. Between NO and NO he focus his work at modern approach to monitoring and distributed storage ===== Main Talk Shannon's “A Mathematical Theory of Communication” is one of those rare papers that defined an entire field of study. (In fact, a year later, it was republished as “THE Mathematical Theory of Communication.”) It provided a unified understanding of communication systems, pulling together work from disparate disciplines like physics, electronics and telegraphy. In this paper, Shannon demonstrates that information is a measurable quantity, and transmission of information can be optimized to achieve fundamental, previously unknown limits. It's one of those papers that underlies so much of modern information theory that the material feels intensely familiar to readers now. In addition, it has a bunch of fun tidbits, including the great-grandfather of ebooks Twitter accounts. I'll provide a quick history of the field before 1948, discuss the main results of the paper, and mention some of the fun (and occasionally counter-intuitive!) implications of the paper. [0] http://worrydream.com/refs/Shannon%20-%20A%20Mathematical%20Theory%20of%20Communication.pdf Kiran's Bio Kiran Bhattaram loves making things, whether tinkering with circuits, writing software systems, or sewing dresses. She works on Stripe’s infrastructure team, and has previously built things for the New York Times, LinkedIn and MIT CSAIL.

Dorothie & Martin Hellman: "Peace, True Love.... and Cryptography" | Talks at Google
 
52:18
Turing Award winner Martin Hellman, along with his wife Dorothie, discuss their book, “A New Map for Relationships: Creating True Love at Home & Peace on the Planet,” and how they went from being madly in love at first, to heading for divorce, then madly in love again--explaining how the same lessons they had to learn in their marriage can help avert worldwide catastrophes such as global warming and nuclear war. Former US Ambassador to Afghanistan Karl Eikenberry has referred to the Hellman’s work as, “the most thoughtful, unique, and fascinating book I have ever read on personal and international diplomacy.” Stories from Marty’s work in cryptography help illustrate ethical dilemmas and the importance of “getting curious, not furious.” “A New Map” can be downloaded for free at: https://anewmap.com/ Dorothie Hellman worked as a CPA at Touche Ross, later becoming a full-time volunteer and VP for Financial Support at the Beyond War Foundation from 1982-87. Since then, she has devoted her life to studying how to improve the human condition. Martin Hellman is best known for his invention, with Diffie and Merkle, of public key cryptography, to enable secure Internet transactions. He currently works on reducing existential risks posed by technology, with an emphasis on nuclear weapons. He is Professor Emeritus of EE at Stanford University, and was awarded the Turing Award in 2015.

Cooking with Cryptography by Fraser Tweedale
 
35:02
The ``cryptography`` library emerged in 2014 with the goal of becoming Python's "cryptographic standard library". It is designed to be easy to use but flexible, exposing a *recipes* layer for common use cases, and a *hazmat* layer that provides crypto primitives but demands users know what they're doing in order to use them properly. This talk will explain the motivations and goals of the ``cryptography`` library, take a tour of its features and discuss its implementation. ``cryptography`` will be compared to some other popular and emerging crypto libraries. Finally, we will examine some real-world use of the library. Audience members should have a passing familiarity with cryptography (e.g. know the differences between hashing and encryption, or public key and private key crypto) to get the most out of this talk. PyCon Australia is the national conference for users of the Python Programming Language. In 2015, we're heading to Brisbane to bring together students, enthusiasts, and professionals with a love of Python from around Australia, and all around the World.

Why did we do this? How did we do it? What mistakes did we make? What doesn.t the documentation tell you? This presentation will tell you what mistakes we made, so you don.t have to. Attendees will gain: A better understanding of what a PKI is and what it isn.t What it does and what you can use it for What is involved in a successful implementation Most of all you get to learn what mistakes we made, so you don.t have to. It will present real world experience, not just theory A lot has been written about PKI, but most of it is wrong We really did do a successful PKI implantation You get to avoid my mistakes.
