Cryptography: The Science of Making and Breaking Codes
 
08:21
There are lots of different ways to encrypt a message, from early, simple ciphers to the famous Enigma machine. But it’s tough to make a code truly unbreakable.

Cryptography: Crash Course Computer Science #33
 
12:33
Today we’re going to talk about how to keep information secret, and this isn’t a new goal. From as early as Julius Caesar’s Caesar cipher to Mary, Queen of Scots, encrypted messages to kill Queen Elizabeth in 1587, theres has long been a need to encrypt and decrypt private correspondence. This proved especially critical during World War II as Allan Turing and his team at Bletchley Park attempted to decrypt messages from Nazi Enigma machines, and this need has only grown as more and more information sensitive tasks are completed on our computers. So today, we’re going to walk you through some common encryption techniques such as the Advanced Encryption Standard (AES), Diffie-Hellman Key Exchange, and RSA which are employed to keep your information safe, private, and secure. Note: In October of 2017, researchers released a viable hack against WPA2, known as KRACK Attack, which uses AES to ensure secure communication between computers and network routers. The problem isn't with AES, which is provably secure, but with the communication protocol between router and computer. In order to set up secure communication, the computer and router have to agree through what's called a "handshake". If this handshake is interrupted in just the right way, an attacker can cause the handshake to fault to an insecure state and reveal critical information which makes the connection insecure. As is often the case with these situations, the problem is with an implementation, not the secure algorithm itself. Our friends over at Computerphile have a great video on the topic: https://www.youtube.com/watch?v=mYtvjijATa4 Produced in collaboration with PBS Digital Studios: http://youtube.com/pbsdigitalstudios Want to know more about Carrie Anne? https://about.me/carrieannephilbin The Latest from PBS Digital Studios: https://www.youtube.com/playlist?list=PL1mtdjDVOoOqJzeaJAV15Tq0tZ1vKj7ZV Want to find Crash Course elsewhere on the internet?

Cryptography For Beginners
 
45:18
Cryptography is a complex and confusing subject. In this talk you will learn about the core components of cryptography used in software development: securing data with encryption, ensuring data integrity with hashes and digital signatures, and protecting passwords with key derivation functions. While learning how to use these components, you will also learn the best practices that drive strong cryptography. This talk won’t make you a cryptography expert but it will give you the knowledge necessary to use cryptography properly. No prior knowledge of cryptography is required for this presentation.

Cybersecurity is a set of techniques to protect the secrecy, integrity, and availability of computer systems and data against threats. In today’s episode, we’re going to unpack these three goals and talk through some strategies we use like passwords, biometrics, and access privileges to keep our information as secure, but also as accessible as possible. From massive Denial of Service, or DDos attacks, to malware and brute force password cracking there are a lot of ways for hackers to gain access to your data, so we’ll also discuss some strategies like creating strong passwords, and using 2-factor authentication, to keep your information safe.

ASMR stands for Autonomous Sensory Meridian Response. It's a non-scientific word that an everyday person came up with to describe the feeling characterized as a pleasurable tingling sensation felt in the head, scalp, back and other regions of the body in response to visual, auditory, tactile, olfactory, and/or cognitive stimuli, such as crinkling bags, hand movements, whispering, personal attention or watching someone perform a task. It's like goosebumps but much more pleasant and without the uncomfortable chills. ASMR videos are meant to intentionally induce this sensation in the viewer, often referred to as "tingles", but the videos also serve to provide a relaxing, calming and soothing experience for the viewer. Many people who do not experience ASMR still enjoy the videos for their calming and sleepy effect.

Abstract: In recent years, lattice-based cryptography has been recognized for its many attractive properties, such as strong provable security guarantees and apparent resistance to quantum attacks, flexibility for realizing powerful tools like fully homomorphic encryption, and high asymptotic efficiency. Indeed, several works have demonstrated that for basic tasks like encryption and authentication, lattice-based primitives can have performance competitive with (or even surpassing) those based on classical mechanisms like RSA or Diffie-Hellman. However, there still has been relatively little work on developing lattice cryptography for deployment in real-world cryptosystems and protocols. In this work, we take a step toward that goal, by giving efficient and practical lattice-based protocols for key transport, encryption, and authenticated key exchange that are suitable as "drop-in" components for proposed Internet standards and other open protocols. The security of all our proposals is provable based (sometimes in the random-oracle model) on the well-studied "leaning with errors over rings" problem, and hence on the conjectured worst-case hardness of problems on ideal lattices (against quantum algorithms). One of our main technical innovations (which may be of independent interest) is a simple, low-bandwidth reconciliation technique that allows two parties who "approximately agree" on a secret value to reach exact agreement, a setting common to essentially all lattice-bases encryption schemes. Our technique reduces the ciphertext length of prior (already compact) encryption schemes nearly twofold, at essentially no cost.

Cryptography in a post-Snowden era - Bart Preneel
 
01:33:58
This lecture presents an overview of the Snowden revelations and the impact on our understanding of the security of our networks and systems. In particular, we discuss the known ways in which sophisticated attackers can bypass or undermine cryptography. We also speculate on how three-letter agencies could be breaking most encryption on the Internet. We relate this to the latest developments in cryptanalysis and discuss which cryptographic algorithms and implementations to select to stay protected. Learning objectives + Understand how sophisticated opponents agencies can undermine cryptographic protection + Understand how to maximize your chances to resist sophisticated opponents using cryptographic techniques This lecture was delivered by Bart Preneel at SecAppDev 2016, Leuven, Belgium Professor Bart Preneel of KU Leuven heads the iMinds COSIC (COmputer Security and Industrial Cryptography) research group.

Keeping Secrets: Cryptography In A Connected World
 
01:26:02
Josh Zepps, Simon Singh, Orr Dunkelman, Tal Rabin, and Brian Snow discuss how, since the earliest days of communication, clever minds have devised methods for enciphering messages to shield them from prying eyes. Today, cryptography has moved beyond the realm of dilettantes and soldiers to become a sophisticated scientific art—combining mathematics, physics, computer science, and electrical engineering. It not only protects messages, but it also safeguards our privacy. From email to banking transactions, modern cryptography is used everywhere. But does it really protect us? What took place was a discussion of cryptography’s far-reaching influence throughout history from Julius Caesar’s reign to Julian Assange’s WikiLeaks, and the ways in which it—and our privacy—are constantly under assault today as threats lurk behind IP addresses, computational power increases, and our secrets move online. The World Science Festival gathers great minds in science and the arts to produce live and digital content that allows a broad general audience to engage with scientific discoveries. Our mission is to cultivate a general public informed by science, inspired by its wonder, convinced of its value, and prepared to engage with its implications for the future.

Voynich Manuscript
 
45:37
The Voynich manuscript, described as "the world's most mysterious manuscript", is a work which dates to the early 15th century (1404--1438), possibly from northern Italy. It is named after the book dealer Wilfrid Voynich, who purchased it in 1912. Some pages are missing, but there are now about 240 vellum pages, most with illustrations. Much of the manuscript resembles herbal manuscripts of the 1500s, seeming to present illustrations and information about plants and their possible uses for medical purposes. However, most of the plants do not match known species, and the manuscript's script and language remain unknown. Possibly some form of encrypted ciphertext, the Voynich manuscript has been studied by many professional and amateur cryptographers, including American and British codebreakers from both World War I and World War II. It has defied all decipherment attempts, becoming a famous case of historical cryptology. The mystery surrounding it has excited the popular imagination, making the manuscript a subject of both fanciful theories and novels. None of the many speculative solutions proposed over the last hundred years has yet been independently verified.

History - Secrets Exposed - Cryptology - WWII Code breaking
 
12:36
From VOA Learning English, this is EXPLORATIONS in Special English. I'm Jeri Watson. And I'm Jim Tedder. Today we visit a small museum in the American state of Maryland. It is called the National Cryptologic Museum. There you will find information that was once secret. The National Cryptologic Museum is on Fort George G. Meade, a military base near Washington, DC. It tells the story of cryptology and the men and women who have worked in this unusual profession. The word cryptology comes from the Greek "kryptos logos." It means "hidden word." Cryptology is writing or communicating in ways designed to hide the meaning of your words. The museum has many examples of equipment that was once used to make information secret. It also has equipment that was developed to read secret messages. The method of hiding exact meanings is called coding. People have used secret codes throughout history to protect important information. One display at the museum explains American attempts to read Japanese military information during World War Two. Japan's Navy used special machines to change its written information into secret codes. This coded information was then sent by radio to navy ships and military bases. The information included secret military plans and orders. The leaders of the Japanese Navy believed no one could read or understand the secret codes. They were wrong. Americans were working very hard to learn the Japanese code. The United States urgently needed to break the code to learn what Japan was planning. In 1940, an American woman named Genevieve Grotjan found some information being repeated in Japanese coded messages. At the time, she was a civilian working for the government in Washington, DC. Her discovery helped the United States understand secret Japanese diplomatic messages. After the United States understood the code, it was possible to study messages from the Japanese ambassador to Germany and to his supervisors in Japan. After the attack on Pearl Harbor, an American Naval officer named Joseph Rochefort struggled to understand the Japanese navy code. He worked on the American base at Pearl Harbor. It was early in 1942. The American naval commander in the Pacific Ocean was Chester Nimitz. His forces were much smaller than the Japanese Naval forces. And the Japanese had been winning many victories. Joseph Rochefort had worked for several months to read the secret Japanese Naval code called JN-25. If he could understand enough of the code, he would be able to give Admiral Nimitz very valuable information. The admiral could use this information to plan for battle. By the early part of the year, Mr. Rochefort and the men who worked with him could read a little less than 20 percent of the Japanese JN-25 code. Joseph Rochefort had the evidence he needed. "AF" was now known to be the island of Midway. He also told Admiral Nimitz the Japanese would attack Midway on June third. The admiral secretly moved his small force to an area near Midway and waited for the Japanese Navy. The battle that followed was a huge American victory. Experts now say the Battle of Midway was the beginning of the American victory in the Pacific. That victory was possible because Joseph Rochefort learned to read enough of the Japanese code to discover the meaning of the letters "AF." One American code has never been broken. Perhaps it never will. It was used in the Pacific during World War Two. For many years the government would not discuss this secret code. Listen for a moment to this very unusual code. Then you may understand why the Japanese military forces were never able to understand any of it. The code is in the voice of a Native American. The man you just heard is singing a simple song in the Navajo language. Very few people outside the Navajo nation are able to speak any of their very difficult language. At the beginning of World War Two, the United States Marine Corps asked members of the Navajo tribe to train as Code Talkers. The Cryptologic Museum says the Marine Corps Code Talkers could take a sentence in English and change it into their language in about 20 seconds. A code machine needed about 30 minutes to do the same work. The Navajo Code Talkers took part in every battle the Marines entered in the Pacific during World War Two. The Japanese were very skilled at breaking codes. But they were never able to understand any of what they called "The Marine Code." Perhaps the most famous is a World War Two German code machine called the Enigma. The word "enigma" means a puzzle or a problem that is difficult to solve. The German military used the Enigma machine to communicate orders and plans. The United States, Britain, and the government of Poland cooperated in learning to read information sent by the Enigma. It took thousands of people and cost millions of dollars to read the Enigma information. This is a VOA product and is in the public domain

Stephen Budiansky, "Code Warriors"

http://www.politics-prose.com/book/9780385352666 Budiansky is on the editorial board of Cryptologia, and he includes fascinating details on the art and science of cryptology as he traces the NSA from its roots in the Second World War’s code breaking programs, such as the one that cracked Enigma. A former national security correspondent and author of books including Her Majesty’s Spymaster and Blackett’s War, Budiansky profiles many spies and cryptologists, outlines the special challenges of ciphers, and follows the Agency’s changing mission as the enemies became less clearly defined in the Cold War; no longer focusing on military personnel, the NSA went after suspected spies, and their targets were increasingly likely to be American citizens, a practice that has only intensified since 9/11.
