Programming in C: Lesson 21 - Arrays, letter frequency analysis, and encryption
 
10:22
In this lecture I introduce the concept of an "array" in C. I use this data structure to count the number of times each letter appears in a file. Then I use simple ASCII graphics to display the frequency in the terminal windows. This illustrates how we can "crack" simple encryption algorithms.

This is a demo of a Perl script I wrote that allows a user to perform frequency analysis. I wrote it just for fun. I was inspired by Simon Singh's - The Code Book. I'm not sure how realistic this application is, but I wrote it as a part of a learning process rather. So why did I write it? Well I find crytography interesting and have been reading Modern Perl and wanted to integrate both applications :) The video is best seen in 720p, full screen :) The song is called: Allegretto grazioso e dolce by Adam Aleksander.

What is POLYGRAPHIC SUBSTITUTION? What does POLYGRAPHIC SUBSTITUTION mean?

What is POLYGRAPHIC SUBSTITUTION? What does POLYGRAPHIC SUBSTITUTION mean? POLYGRAPHIC SUBSTITUTION meaning - POLYGRAPHIC SUBSTITUTION definition - POLYGRAPHIC SUBSTITUTION explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ A polygraphic substitution is a cipher in which a uniform substitution is performed on blocks of letters. When the length of the block is specifically known, more precise terms are used: for instance, a cipher in which pairs of letters are substituted is bigraphic. As a concept, polygraphic substitution contrasts with monoalphabetic (or simple) substitutions in which individual letters are uniformly substituted, or polyalphabetic substitutions in which individual letters are substituted in different ways depending on their position in the text. In theory, there is some overlap in these definitions; one could conceivably consider a Vigenere cipher with an eight-letter key to be an octographic substitution. In practice, this is not a useful observation since it is far more fruitful to consider it to be a polyalphabetic substitution cipher. In 1563, Giambattista della Porta devised the first bigraphic substitution. However, it was nothing more than a matrix of symbols. In practice, it would have been all but impossible to memorize, and carrying around the table would lead to risks of falling into enemy hands. In 1854, Charles Wheatstone came up with the Playfair cipher, a keyword-based system that could be performed on paper in the field. This was followed up over the next fifty years with the closely related four-square and two-square ciphers, which are slightly more cumbersome but offer slightly better security. In 1929, Lester S. Hill developed the Hill cipher, which uses matrix algebra to encrypt blocks of any desired length. However, encryption is very difficult to perform by hand for any sufficiently large block size, although it has been implemented by machine or computer. This is therefore on the frontier between classical and modern cryptography. Polygraphic systems do provide a significant improvement in security over monoalphabetic substitutions. Given an individual letter 'E' in a message, it could be encrypted using any of 52 instructions depending on its location and neighbors, which can be used to great advantage to mask the frequency of individual letters. However, the security boost is limited; while it generally requires a larger sample of text to crack, it can still be done by hand. One can identify a polygraphically-encrypted text by performing a frequency chart of polygrams and not merely of individual letters. These can be compared to the frequency of plaintext English. The distribution of digrams is even more stark than individual letters. For example, the six most common letters in English (23%) represent approximately half of English plaintext, but it takes only the most frequent 8% of the 676 digrams to achieve the same potency. In addition, even in a plaintext many thousands of characters long, one would expect that nearly half of the digrams would not occur, or only barely. In addition, looking over the text one would expect to see a fairly regular scattering of repeated text in multiples of the block length and relatively few that are not multiples. Cracking a code identified as polygraphic is similar to cracking a general monoalphabetic substitution except with a larger 'alphabet'. One identifies the most frequent polygrams, experiments with replacing them with common plaintext polygrams, and attempts to build up common words, phrases, and finally meaning. Naturally, if the investigation led the cryptanalyst to suspect that a code was of a specific type, like a Playfair or order-2 Hill cipher, then they could use a more specific attack.

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.

Caesar Cipher Encryption and Decryption in Python
 
11:23
Ceasar Cipher in Python Hi!! In this video I'll be doing ceasar cipher encryption and decryption using Python Caesar Cipher is subsitution cipher, its algorithm is as following: - Take alphabetic message (A to Z) - Take a key (1 to 26) (1 being A and 26 being Z) - To encrypt, left-shift or right-shift message letter by letter by the value of key For example if message is "ABC" and key is 1 and we are performing right-shift then encrypted text will be A+1 = B, B+1 = C, C+1 = D. ABC = BCD, BCD being encrypted text. - To decrypt, left-shift or right-shift the message letter by letter opposite to the shift performed in encryption by the value of key For example if encrypted text is "BCD" and key is 1 and we are performing left-shift then encrypted text will be B-1 = A, C-1 = B, D-1 = C. BCD = ABC, ABC being decrypted text.

Top 10 Cyber Security Facts | Cryptography, Data Breach, Decryption, Firewall, Crudware, Honeypot
 
04:05
Top 10 facts about Cyber Security On number 10 there is Cryptography A Cryptography involves creating written or generated codes that allows information to be kept secret. Cryptography converts data into a format that is unreadable for an unauthorized user, allowing it to be transmitted without anyone decoding it back into a readable format, thus compromising the data. On number 9 there is Data Breach A data breach is an incident that involves the unauthorized or illegal viewing, access or retrieval of data by an individual, application or service. It is a type of security breach specifically designed to steal and/or publish data to an unsecured or illegal location. A data breach is also known as a data spill or data leak. On number 8 there is Backdoor A backdoor is a technique in which a system security mechanism is bypassed undetectably to access a computer or its data. The backdoor access method is sometimes written by the programmer who develops a program. A backdoor is also known as a trapdoor. On number 7 there is Encryption Encryption is the process using an algorithm for tagging information to make it unreadable for unauthorized users. This cryptographic method protects sensitive data such as credit card numbers by encoding and transforming information into unreadable cipher text. This encoded data may only be decrypted or made readable with a key. Symmetric-key and asymmetric-key are the two primary types of encryption. On number 6 there is honeypot A honeypot is a decoy computer system for trapping hackers or tracking unconventional or new hacking methods. Honeypots are designed to purposely engage and deceive hackers and identify malicious activities performed over the Internet. Multiple honeypots can be set on a network to form a honeynet. On number 5 there is Crudware A Crudware is a type of freeware and software marketing tactic in which large quantities of beta, trial, freeware or limited software versions are freely distributed or promoted on websites, social networks and related online communities. Crudware is used to lure and motivate prospective customers into purchasing a complete or paid version of the software, or even malware. On number 4 there is Vulnerability A vulnerability is a cyber-security term that refers to a flaw in a system that can leave it open to attack. Vulnerability may also refer to any type of weakness in a computer system itself, in a set of procedures, or in anything that leaves information security exposed to a threat. On number 3 there is Hacktivism A Hacktivism is the act of hacking a website or computer network in an effort to convey a social or political message. The person who carries out the act of hacktivism is known as a hacktivist. On number 2 there is Firewall A firewall is software used to maintain the security of a private network. Firewalls block unauthorized access to or from private networks and are often employed to prevent unauthorized Web users or illicit software from gaining access to private networks connected to the Internet. A firewall may be implemented using hardware, software, or a combination of both. On number 1 there is Decryption A Decryption is the process of transforming data that has been rendered unreadable through encryption back to its unencrypted form. In decryption, the system extracts and converts the garbled data and transforms it into texts and images that are easily understood not only by the reader but also by the system. Decryption may be accomplished manually or automatically. It may also be performed with a set of keys or passwords. ▶DONT CLICK THIS - https://goo.gl/p9DRXs

READ THIS, IMPORTANT! THIS IS THE STORY! **distribution of work at the bottom What you have just witnessed awhile ago is an example of a cryptogram. According to Merriam-Webster, a cryptogram is text written in code, and comes from the greek words crypto and gram, together meaning "hidden letter". Now, these cryptograms are rewritten using what you call " ciphers", which allows the message to seemingly make no sense. In the video, Satchel Wayne saw a cryptogram written on the board of the room, and decided to decipher it. At the start, the text may look like jibberish, and it is, but as a person familiar with puzzles, Satchel Wayne believed it to be one, so he searched for books to aide him in his deciphering. Now if you noticed what Satchel was attempting, he was first using a technique called frequency analysis. Here, one may be able to guess which letters are assigned to which by noticing which letters occur the most in the cipher. An example is when one may see several v's in the message, implying that it is a letter frequently used such as A, T, or E. This will also lessen the number of combinations that you may try using to guess the code. With this, he was able to guess some letters. Now, he immediately thought of possible encryption methods that the cryptogram was written with, with him coming across the keyword cipher. Here, a keyword is used in correspondence with the letters of the alphabet, wherein the keyword will serve as the replacement for the first letters of the alphabet and will shift the alphabet as well. With his clever thinking too, Wayne was able to see this and think of possible keywords, and by remembering "Rubiko", he came up with words related to it and eventually found " algorithm" which was luckily correct. All in all, with frequency analysis, the idea of a keyword cipher and of course Satchel Wayne's precise thinking, he was able to decode the message. Too bad it was in vain, as the people in the room are not really the ones who wrote it, and the secret of El Rubiko De Python will remain intact.

What is CIPHERTEXT-ONLY ATTACK? What does CIPHERTEXT-ONLY ATTACK mean? CIPHERTEXT-ONLY ATTACK meaning - CIPHERTEXT-ONLY ATTACK definition - CIPHERTEXT-ONLY ATTACK explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ In cryptography, a ciphertext-only attack (COA) or known ciphertext attack is an attack model for cryptanalysis where the attacker is assumed to have access only to a set of ciphertexts. While the attacker has no channel providing access to the plaintext prior to encryption, in all practical ciphertext-only attacks, the attacker still has some knowledge of the plaintext. For instance, the attacker might know the language in which the plaintext is written in or the expected statistical distribution of characters in the plaintext. Standard protocol data and messages are commonly part of the plaintext in many deployed systems and can usually be guessed or known efficiently as part of a ciphertext-only attack on these systems. The attack is completely successful if the corresponding plaintexts can be deduced, or even better, the key. The ability to obtain any information at all about the underlying plaintext beyond what was pre-known to the attacker is still considered a success. For example, if an adversary is sending ciphertext continuously to maintain traffic-flow security, it would be very useful to be able to distinguish real messages from nulls. Even making an informed guess of the existence of real messages would facilitate traffic analysis. In the history of cryptography, early ciphers, implemented using pen-and-paper, were routinely broken using ciphertexts alone. Cryptographers developed statistical techniques for attacking ciphertext, such as frequency analysis. Mechanical encryption devices such as Enigma made these attacks much more difficult (although, historically, Polish cryptographers were able to mount a successful ciphertext-only cryptanalysis of the Enigma by exploiting an insecure protocol for indicating the message settings). More advanced ciphertext-only attacks on the Enigma were mounted in Bletchley Park during World War II, by intelligently guessing plaintexts corresponding to intercepted ciphertexts. Every modern cipher attempts to provide protection against ciphertext-only attacks. The vetting process for a new cipher design standard usually takes many years and includes exhaustive testing of large quantities of ciphertext for any statistical departure from random noise. See: Advanced Encryption Standard process. Also, the field of steganography evolved, in part, to develop methods like mimic functions that allow one piece of data to adopt the statistical profile of another. Nonetheless poor cipher usage or reliance on home-grown proprietary algorithms that have not been subject to thorough scrutiny has resulted in many computer-age encryption systems that are still subject to ciphertext-only attack.

J.R. Watts: Shroud Codes In The Bible • The Scott Helmer Show - 03.27.17
 
02:03:44
Source: https://www.spreaker.com/user/scotthelmershow/j-r-watts-shroud-codes-in-the-bible-the-_2 SHROUD OF TURIN MYSTERY SOLVED BY GOV'T CODE-BREAKER! In 2012; former government investigator, intelligence analyst & code-breaker, J.R. Watts, launched a 5 year research project to finally answer the question: Did Christ's disciples hide clues about the SHROUD OF TURIN in the New Testament? What he discovered were cryptic forms of word camouflage known to cryptologists as: open codes, null ciphers & jargon codes, arranged in diffused layers of data in the Bible. They describe the Shroud in intermittent signals, symbolic references, disguised metaphors & phonetically spelled ciphers. But their common denominator was JESUS' IMAGE ON THE SHROUD! Watts used the same code-breaking methods the CIA & NSA utilize when cracking codes, such as pattern recognition, quantitative data analysis, detection of graphical deception, cluster analysis, data mining, frequency analysis, camouflage signaling & correspondence analysis. Learn how the disciples became adept at layering their words with telltale hints about the Shroud. See why these codes remained INVISIBLE to the clergy & Shroud experts, who lack cryptology skills. Watts also points to Old Testament verses that cloaked the Shroud in the abstract of Scripture. He says the Shroud Codes were no accident; they were there all the time, waiting for us, like a hidden dossier. It was the safest way to write about Christ's miraculous image because it subtly obscured the medium on which it existed: a shroud. The SCIENCE OF CRYPTOLOGY proves the Shroud of Turin covered the body of Jesus! BONUS INFO: J.R. WATTS REVEALS THE HARBINGERS ALL THE PROPHECY WATCHERS MISSED: Learn about the resurrection of the Exodus 32 Golden Calf Idol, REBORN in New York City's New Millennium Cow Parade in 2000. In Moses' time 3,000 people were killed in 1 day for false idolatry. On 9-11; 3,000 people were again slain in 1 day, surrounded by the SAME false idols. The book has 6 dozen color photos & free 3D glasses to view the Shroud in 3D! J.R. Watts worked as an investigator for various government agencies in New York City for more than two decades, as well as for government intelligence contractors. But behind the scenes; he was also a code-breaker, having been educated in cryptanalysis and cryptography. He was also a Shroud of Turin researcher.

Blockchain Beyond Bitcoin - with Vinay Gupta | Virtual Futures Salon
 
01:32:20
Virtual Futures presents tech-visionary Vinay Gupta to dicuss cryptocurrencies and the uptake of the blockchain in all its applications. This event is organised in partnership with the Department of Economics at the University of Warwick as part of their 360 Lecture Series. Blockchain, also known as distributed ledger technology, has attracted a great deal of attention due to the hype surrounding cryptocurrencies like Bitcoin. Whilst blockchain technology might be able to drive economic change globally, the applications are innumerable. Among others, the implications include empowering impoverished individuals by bypassing banks for payments, generating personalized identities for voting, securing healthcare data, improving supply chain logistics, and allowing business to be carried out transparently. Vinay will share his thoughts on how a technology that permits secure and transparent solutions might transform the next decade. Vinay Gupta is a leading figure in the blockchain space. He is the co-founder of Mattereum, co-ordinated the release of the blockchain platform Ethereum in July 2015, and was strategic architect for ConsenSys, a technology hub focusing on the Ethereum blockchain and related applications. He was the designer of the National Blockchain Strategy for Dubai and is a partner at Hexayurt Capital, the technology-focused VC firm behind the Internet of Agreements. He has been involved in commercial software development since 1992 and his experience as a programmer and visionary has covered fields as diverse as medical imaging, flight simulation, computer graphics, cryptographic applications and the web.

Whole video is real-time. This is why you don't reuse stream cipher keys, kids. Further explanation below the fold. The script uses a fitness function that determines the quality of each decrypted ciphertext based on whether the characters are in the printable ascii range (or nl/cr/tab) and gives better scores for letters. Further checking is done using a wordlist sorted by word frequency to look at whether the output makes sense, and to generate better guesses.
