The Zodiac Ciphers - What do we know, and when do we stop trying to solve them?
 
37:36
http://zodiackillerciphers.com This is a talk I gave at the 2015 Cryptologic History Symposium on October 22, 2015. I've been studying the Zodiac ciphers for a while now, and this presentation is a culmination of my research. The talk was part of the "Ciphers and Crime" panel moderated by FBI historian John Fox. Fellow panelists included FBI Cryptanalysis and Racketeering Records Unit chief Dan Olson and encryption technology author Klaus Schmeh. For much more information about the Zodiac Ciphers, please visit http://zodiackillerciphers.com Some bits of the audio dropped out due to technical issues with my sound recorder - apologies for the parts that are hard to understand! BONUS MATERIAL: At the end of the video, I recorded some new material on miscellaneous things I didn't have time to include in the presentation. ERRATA: At 28m59s, I say the 408 is missing a word or phrase between parts 1 and 2. But actually it is missing between parts 2 and 3.

How secure is 256 bit security?
 
05:06
Supplement to the cryptocurrency video: How hard is it to find a 256-bit hash just by guessing and checking? What kind of computer would that take? Cryptocurrency video: https://youtu.be/bBC-nXj3Ng4 Thread for Q&A questions: http://3b1b.co/questions Several people have commented about how 2^256 would be the maximum number of attempts, not the average. This depends on the thing being attempted. If it's guessing a private key, you are correct, but for something like guessing which input to a hash function gives a desired output (as in bitcoin mining, for example), which is the kind of thing I had in mind here, 2^256 would indeed be the average number of attempts needed, at least for a true cryptographic hash function. Think of rolling a die until you get a 6, how many rolls do you need to make, on average?

As technology increases, so do the methods of encryption and decryption we have at our disposal. World War II saw wide use of various codes from substitution ciphers to employing Navajo code talkers in the Pacific theater. Here, science journalist and author Simon Singh demonstrates the German enigma machine, a typewriter-like device used to encrypt communications. He demonstrates not only its operation, but both the strength and fatal flaws in its method.

Lorenz: Hitler's "Unbreakable" Cipher Machine
 
11:43
Many people have heard of Enigma before, the code machine used by Nazi Germany to send secret coded messages. Yet, some very clever code breakers were able to break that code and read those messages! But there was another cipher machine used by the Germans in WWII called the Lorenz machine, and this machine was even more difficult than Enigma, and was used by the top level of the Nazi Party. However the code breakers at Bletchley Park broke this code too, and could read secret messages from people like Adolf Hitler himself! It was mathematician Bill Tutte who discovered the breakthrough that allowed the Lorenz code to be broken. On the 10th of September 2014 a new memorial to Bill Tutte is unveiled in his hometown of Newmarket. Have a look at the Bill Tutte Memorial website at http://billtuttememorial.org.uk/

Bitcoins are mined using a cryptographic algorithm called SHA-256. This algorithm is simple enough to be done with pencil and paper, as I show in this video. Not surprisingly, this is a thoroughly impractical way to mine. One round of the algorithm takes 16 minutes, 45 seconds which works out to a hash rate of 0.67 hashes per day.

Mass Effect Andromeda - All Glyph Puzzle Solutions & Locations (Cryptographer Trophy Guide)
 
22:26
There are 20 Remnant Glyph Puzzle Solutions & Locations in Mass Effect Andromeda. Solving all puzzles unlocks the Cryptographer trophy or achievement. This guide shows them in chronological story order. Text & Screenshot Guide for All Glyph Puzzles: http://www.powerpyx.com/mass-effect-andromeda-glyph-puzzle-solutions-locations/ For "Cryptographer" you must solve all 20 puzzles in a single playthrough. This is HIGHLY MISSABLE! 6 out of 20 puzzles are missable because they are inside remnant vaults that cannot be revisited after completing them, or in quest areas you can't go back to. The missable ones are marked in the overview below. Most of them are located at Alien Monoliths or inside Remnant Vaults. Each vault contains at least 1 missable puzzle! If you miss a puzzle it will lock you out of the trophy. The Remnant Puzzles are similar to Sudoku. First you must locate hidden glyphs (they are always in close proximity to the puzzle). Use your scanner to follow the yellow cables from the remnant console to the glyphs and scan them. Now you must decrypt the Remnant Code by assigning the glyphs to a grid. No row or column can include repeats of the same glyph (only one glyph of each type per line). The same goes for each quadrant block (usually four quadrants divided by glowing lines). You can't have two of the same glyphs in one quadrant. Start with the lines or blocks that are only missing one glyph. This will immediately give you the last glyph for that line (whichever one is not in the line yet). Then move to the lines that are missing 2 glyphs. Piece by piece you’ll get closer to the correct combination. You can also use Remnant Decryption Keys to solve the puzzle immediately (items that are sometimes found in chests). TIMELINE (sorted by planets and quests): Planet: EOS #1 - Main Mission: A Better Beginning - 0:05 #2 - [MISSABLE] Main Mission: A Better Beginning - 1:14 #3 - Free Roam / Additional Task: Data Trail - 3:40 #4 - Free Roam / Additional Task: The Ghost of Promise - 5:38 Planet: Havarl *You can choose whether to go to Havarl or Voeld first.

Crypto Defenses for Real-World System Threats - Kenn White - Ann Arbor
 
01:36:58
Modern encryption techniques provide several important security properties, well known to most practitioners. Or are they? What are in fact the guarantees of, say, HTTPS TLS cipher suites using authenticated encryption, IPSec vs. SSL VPNs, Property Preserving Encryption, or token vaults? We live in an era of embedded Hardware Security Modules that cost less than $1 in volume, and countless options now exist for encrypting streaming network data, files, volumes, and even entire databases. Let's take a deep dive into the edge of developed practice to discuss real-world threat scenarios to public cloud and IoT data, and look closely at how we can address specific technical risks with our current encryption toolkits.

Scytale Cipher Encryption - CISSP
 
04:43
------------------------------------------------------------------------------------------------------ Scytale Cipher Encryption -------------------------------------------------------------------------------------------------------- The ancient Egyptians and Greeks, particularly the Spartans used the Scytale cipher to encrypt messages. It was a simple transposition cipher that could be cracked fairly easily but in the heat of battle would have been useful. The key was the diameter of the "stick" had to be identical for the code to work. For this demo I'm using a glass and a can of paint, but you get the idea.

How quantum physics can make encryption stronger | Vikram Sharma
 
11:54
As quantum computing matures, it's going to bring unimaginable increases in computational power along with it -- and the systems we use to protect our data (and our democratic processes) will become even more vulnerable. But there's still time to plan against the impending data apocalypse, says encryption expert Vikram Sharma. Learn more about how he's fighting quantum with quantum: designing security devices and programs that use the power of quantum physics to defend against the most sophisticated attacks.

Cryptarithmatic Problems Artificial Intelligence | Solved Example | (Eng-hindi) | #9
 
11:39
Cryptarithmetic is a type of mathematical game consisting of a mathematical equation among unknown numbers, whose digits are represented by letters. The goal is to identify the value of each letter. In this video we learn tips and tricks to solve these verbal arithmetic problems. Cryptarithmetic is the science and art of creating and solving cryptarithms. A cryptarithm is a genre of mathematical puzzle in which the digits are replaced by letters of the alphabet or other symbols. The invention of Cryptarithmetic has been ascribed to ancient China. This art was originally known as letter arithmetic or verbal arithmetic. In India, during the Middle Ages, were developed the arithmetical restorations or "skeletons" a type of cryptarithms in which most or all of the digits have been replaced by asterisks. The word cryptarithmetic ("cryptarithmie" in French) was introduced by M. Vatriquant, writing under the pseudonym Minos, in the May 1931 issue of Sphinx, a Belgian magazine of recreational mathematics published in French from 1931 to 1939. A type of alphametic addition puzzle termed "doubly-true" was introduced in 1945 by Alan Wayne. It is made up of "number words" that, when read, also form a valid sum.

What is a trapdoor function?
 
04:06
Modern cryptography depends on the existence of several special kinds of mathematical functions. One important kind is a trapdoor function. Trapdoor functions are somewhat similar to hash functions in that they are easy to compute but hard to invert…​ except if you know a secret piece of information. So if someone does not have the secret or key, they cannot invert the function. If they do, they can open the trapdoor and invert the function. Trapdoor functions form the basis of modern cryptographic techniques that are widely-used online.
