What is the basis for most modern cryptography?
 
05:46
Trapdoor functions have proven fairly difficult to find. Most modern cryptosystems—​including RSA—​are based on factoring. Given two very large prime numbers it is easy to multiply them together to create a third number that has only two factors. But given that third number it is very hard to determine what it’s two factors are. This asymmetry is the basis of modern cryptography and most of our online security. If anyone ever determines how to quickly factor huge numbers, it will have enormous and incredibly disruptive societal consequences.

The Information Age - The Power of Cryptography & Encryption (With Captions)
 
03:30
http://www.illumingati.co.nz "The development of Cryptography I have been pushing for the past 20 Years, to protect the integrity and privacy of the individuals and the sovereignty of states from domination by these large players" - Julian Assange The exchange of digital information has become an integral part of our society. Already tens of millions of emails are sent each day, the Internet has provided the infrustructure for the digital marketplace, and e-commerce is thriving. Money is flowing through cyberspace, and it as estimated that every day half of the world's gross domestic product travels through the Society for Worldwide Interbank Financial Telecommunications (SWIFT) network. Democrocies that referanda will begin to have online voting, and governments will increasingly use the Internet to help administer their countries, offering facilties such as online tax returns. Without a doubt, the Information Age is under way, and we live in a wired world. Critically, the success of the Information Age depends on the ability to protect the information as it flows around the world, and this relies on the power of cryptography. Encryption can be seen as providing the locks and keys of the information Age. For two thousand years encryption has been importance only to government and the military, but today it also has a role to play in facilitating business, and tomorrow ordinary people will rely on cryptography in order to protect their privacy. Fortunately, just as the Information Age is taking off, access to extraordinary strong encryption. The development of public-key cryptography, particulary the RSA cipher, has given today's cryptographers a clear advantage in their continual power struggle against cryptanalysts. If the value of N is large enough, then finding p and q takes Eve and unreasonable amount of time, and RSA encryption is therefore effectively unbreakable. Most important of all, public-key cryptography is not weakened by any key-distribution problems. In short, RSA guarantees almost unbreakable locks for our most precious pieces of information. However, as with every technology, there is a darkside to encryption. As well as protecting the communications of law-abiding citizens, encryption also protects the communication of criminals and terrorists. Currently, police forces use wiretaping as a way of gathering evidence to counter organized crime and terrorism , but this word be ineffective if criminals used unbreakable ciphers. In the twenty-first century, the fundamental dilema for cryptography is to find a way of allowing the public and businesses to use encryption in order to exploit the benefits of the Information Age, without allowing criminals to abuse encryption and avade arrest. There is currently and active and vigorous debate about the best way forward, and much of the discussion has been inspired by the story of Phil Zimmermann, an American crytographer whose attempts to encourage the widespread use of strong encryption have frightened America's security experts, threatened the billion dollar National Security Agency and made him the subject of a major inquiry and grand-jury investigation.

How Mathematicians Think About Patterns - Professor Ian Stewart
 
01:02:52
There are many kinds of pattern in mathematics and many ways to think about them. But when it comes to visual patterns, one viewpoint stands out; symmetry. This talk explores some basic ideas about symmetry, and shows how it helps us to understand patterns in nature - such as the markings on animals and fish, how animals move, the shapes of sand dunes, and the six-sided snowflake. This the second in a series of three lectures on Patterns. The transcript and downloadable versions of the lecture are available from the Gresham College website: http://www.gresham.ac.uk/lectures-and-events/how-mathematicians-think-about-patterns 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 nearly 1,500 lectures free to access or download from the website.

What are security issues in Cryptography
 
08:58
www.hiteshChoudhary.com www.newdemy.com What are security issues in Cryptography? Why there is a need of Cryptography is a very important question. In the earlier times when one need to transfer any sensitive information, one can write it on paper and can seal it along with manual monitoring system i.e. one person guarding or protecting the information. But after the invention of radio, things got changed. One can tune into your radio without your knowledge and can collect all information. Just collecting the information is not a bug issue but one can modify the information as well. Information security attack is a broad term, so let’s make a few scenario examples to clarify it out on a broad level. Case 1 User A wants to transmit a file to user B. The file may contain some sensitive information like Bank passwords. User C, who is not authorized to read the file, is somehow monitor the transfer and captures a copy of the file during transmission. Case 2 User A wants to transmit a file to user B. User A gives some bank details to open and close new accounts. User C, intercepts the file and add User C’s information to be added and gets a new unauthorized bank account. User C can also delete some valid account information by altering the information. User B updates the details according to information passed by User A, having no idea that information was tempered on its way. Case 3 User A is just relaxing in this case. User C, who is an unauthorized person, just creates his own message and act as a User A and passes the information to User B. User B accepts the message and act according the message. It is totally up to User C that what he wants to do. User C can format all the information or add some backdoor information in the system and so on. Case 4 User C works for the company and due to some reasons C was fires from the company. User A asks the User B, who is an administrator in the company to lock all the access of User C’s account. But User C, creates some useless traffic and delays the message to reach to user B. User c makes a final access to the account and downloads the entire information to local or permanent access. After completing the work he allows the message to get passed. Case 5 A message is sent from user A to user B to purchase xyz share or xyz amount. Things didn’t went in right direction for User A and investment lose value. Now user A denies that he ever passed any message to user B to purchase any share. These are some of the broadly covered situations explaining the need of cryptography. Cryptography gives us a solution to all of these problems. We just have to utilize the concept and put it in some form of codes or protocols to implement it.

MIT's Cryptographic System "Sieve" will help Web Users to control their Personal Data
 
01:29
Most people with smartphones use a range of applications that collect personal information and store it on Internet-connected servers . And, they use similar application s from their Laptop and Desktop also. Some use still other Internet-connected devices, such as thermostats or fitness monitors, that also store personal data online. Generally, users have no idea which data items their apps are collecting, where they’re stored, and whether they’re stored securely. Researchers at MIT and Harvard University hope to change that, with an application they’re calling Sieve. With Sieve, a Web user would store all of his or her personal data, in encrypted form, on the cloud. Any app that wanted to use specific data items would send a request to the user and receive a secret key that decrypted only those items. If the user wanted to revoke the app’s access, Sieve would re-encrypt the data with a new key. Sieve required the researchers to develop practical versions of two cutting-edge cryptographic techniques called attribute-based encryption and key homomorphism Privacy and security are becoming important, the debate between Apple's iPhone encryption and the FBI proves that. This new Cryptographic system would help to address privacy and security issues. News Source: http://news.mit.edu/2016/secure-user-controlled-app-data-0318

Bitcoin 101 - Elliptic Curve Cryptography - Part 4 - Generating the Public Key (in Python)
 
21:22
Welcome to part four in our series on Elliptic Curve Cryptography. I this episode we dive into the development of the public key. In just 44 lines of code, with no special functions or imports, we produce the elliptic curve public key for use in Bitcoin. Better still, we walk you through it line by line, constant by constant. Nothing makes the process clearer and easier to understand than seeing it in straight forward code. If you've been wondering about the secp256k1 (arguably the most important piece of code in Bitcoin), well then this is the video for you. This is part 4 of our upcoming series on Elliptic Curves. Because of such strong requests, even though this is part 4, it is the first one we are releasing. In the next few weeks we will release the rest of the series. Enjoy. Here's the link to our Python code (Python 2.7.6): https://github.com/wobine/blackboard101/blob/master/EllipticCurvesPart4-PrivateKeyToPublicKey.py Here's the private key and the link to the public address that we use.

5 Reasons Why I Love Cryptography By Susan Freed In Atlanta
 
03:12
Five Reasons Why I Love Cryptography http://iheartsusanfreed.com For years, I didn't know anything about cryptography. I'd heard the term, but I didn't know what it meant, or what the practice involved. Still, when I got the chance to study cryptography, I took it, and my life has been richer and more interesting as a result. Cryptography is essentially the study of codes, and learning more about it can benefit your life in all kinds of ways. Below, you'll find five of the reasons I love cryptography. If you learn more about it, there's a good change you'll wind up loving cryptography as much as I do. 1. It makes life more interesting Ever since I started studying cryptography, I've begun to see codes and hidden messages in everything. When I read a letter or look at a sign, I automatically start making connections with my mind. There probably aren't any hidden messages in road signs, but that doesn't matter! Thinking about those things makes my life a lot more interesting, and a lot more fun. 2. It's made me smarter Cryptography is a great way to train your mind and make it sharper than ever before. It helps to improve your concentration as well as your wit. Since I started studying cryptography, I get better scores on tests, and have an easier time studying for classes at school. It's really strengthened my mind. 3. It's given me a more well-rounded education Because of my interest in cryptography, I've studied a number of other subjects. It's given me reason to improve my math and science skills, and to study all kinds of history. I'm more motivated to learn than ever before, and that's helped to educate me in some very interesting ways. Cryptography has given me a better education than I ever would have had without it. I feel like I have little bits of knowledge in all kinds of subjects, and that's really exciting. 4. It's helped me meet some amazing people Because of my passion for cryptography, I've made connections and met people from all over the world. Many of these people are just as passionate about cryptography as I am, and many of them are amazing. The field of cryptography attracts some fascinating and brilliant people. I'm grateful to have met all of them, and I'm very glad that it was cryptography that managed to bring us together. 5. It's a ton of fun! While all of the benefits above are nice, the real reason I love cryptography is that it's fun. No TV show or movie is as exciting as solving a mystery or cracking a puzzle on your own. Cryptography isn't an expensive hobby, but it's definitely an entertaining one. Every day, I always have something interesting to do, and I owe that to cryptography. I highly recommend that everyone learns more about cryptography. It's amazing for more than five reasons, and if you look into it, you'll probably love it too. Cryptography is an absolutely incredible hobby. http://youtu.be/TXplWR7Jr-E http://en.wikipedia.org/wiki/Cryptography

Will Take Supercomputer Age Of Universe To Hack Into Data: Aadhaar Boss
 
03:03
Aadhaar data has been secured by a 2048-encryption key that will take a supercomputer more than the age of universe, or over 13 billion years, to crack, Ajay Bhushan Pandey, the chief of UIDAI which runs the identification programme, told the Supreme Court today. Mr Pandey, who made an 80-minute rare presentation before the five judges of the top court, said once any Aadhaar data reached its central database, it could not be shared with anyone except on grounds of national security.

Universal Computer Authentication (Part 2 of 2)
 
08:24
Two novel and related anti-spam systems that enable the authentication of every mail server and every personal computer in the world. This system is practical because it requires only a one-time software update on behalf of a small handful of software vendors and it can be seamlessly integrated into existing infrastructure. Neither the awareness nor participation of individual users, domain administrators, or server administrators is required for this to function. This narrated PowerPoint was presented at the 8th Annual Collaboration, Electronic messaging, Anti-Abuse and Spam Conference (CEAS2011) in support of one of the conference papers: "Automatic Authentication of Email Servers and Personal Computers Independent of the Active Participation of Server Administrators or Personal Computer Users'

Password Security using  Group Theory Part  2 of 5
 
14:45
Benjamin Fine (Fairfield University). Title: Password Security Using Combinatorial Group Theory Abstract. Joint with: Gilbert Baumslag and Doug Troeger. Over the past decade and a half there has been a concerted effort to apply combinatorial group theoretic methods to cryptographic protocols. In this talk we briefly explain how group theoretic techniques are applied to cryptology and then consider a method to apply group theoretic techniques to password security. Challenge response methods are increasingly used to enhance password security. In particular we present a very secure method for challenge response password verification using combinatorial group theory. This method, which relies on the group randomizer system, a subset of the MAGNUS computer algebra system, handles most of the present problems with challenge response systems. Theoretical security is based on several results in asymptotic group theory and these will be explained as well.

The beauty of such a scheme is that a set of qualified participants is able to recover the secret image without any cryptographic knowledge and computation devices. An extended visual cryptography scheme (EVCS) is a kind of VCS which consists of meaningful shares (compared to the random shares of traditional VCS). In this paper, we propose a construction of EVCS which is realized by embedding random shares into meaningful covering shares, and we call it the embedded EVCS. Experimental results compare some of the well-known EVCSs proposed in recent years systematically, and show that the proposed embedded EVCS has competitive visual quality compared with many of the well-known EVCSs in the literature. In addition, it has many specific advantages against these well-known EVCSs, respectively.

Aswath Damodaran: "The Value of Stories in Business" | Talks at Google
 
01:31:29
The world of investing/finance is divided into two camps. In one, you have the number-crunchers, who believe that the only things that matter are the numbers and that imagination/creativity are dangerous distractions. In the other, you have the storytellers, who build on the stories they tell about companies and how these stories will bring untold wealth. Each side believes it has a monopoly on the truth and looks with contempt at the other. Prof. Damodaran contends that stories matter, but only if they are connected with numbers. And numbers are empty, unless they are connected with narratives. In this talk, he looks at the process by which one might build narratives, check them against reality and convert them into valuations. Uber and Ferrari examples are used to illustrate the process.
