How encryption for iPhone works and why FBI can not decrypt it @apple @FBI @TheJusticeDept
 
02:58
How encryption for iPhone works and why FBI can not decrypt it @apple @FBI @TheJusticeDept Step 1. What is Encryption? Step 2. Symmetric-key encryption Step 3. Same key decrypts message Step 4. Asymmetric key encryption Step 5. Certification authority Step 6. Apple uses a combination of passcode and hardway key to encrypt data Step 7. There are obstacles that stand in the way of guessing the passcode Step 8. FBI wants unlimited way to do passcode guesses Step 9. Encryption is at the heart of this debate 1. What is Encryption? Encryption is the process of encoding messages or information in such a way that only authorized parties can read it. Encryption does not of itself prevent interception, but denies the message content to the interceptor 2. Symmetric-key encryption In symmetric-key encryption the encryption and decryption keys are the same. Communicating parties must have the same key before they can achieve secure communication. 3. Same key decrypts message In symmetric-key encryption the encryption and decryption keys are the same. 4. Asymmetric key encryption In an asymmetric key encryption scheme, anyone can encrypt messages using the public key, but only the holder of the paired private key can decrypt. Security depends on the secrecy of the private key. 5. Certification authority A certification authority is a trusted third party that can issue public and private keys, thus certifying public keys. It also works as a depository to store key chain and enforce the trust factor. 6. Apple uses a combination of passcode and hardway key to encrypt data In Apple iOS devices, nearly all important files are encrypted with a combination of the phone passcode and a hardware key embedded in the device at manufacture time. 7. There are obstacles that stand in the way of guessing the passcode Apple iOS introduces a delay after every incorrect PIN entry,  a delay obstacle that stands in the way of guessing the passcode on  an iPhone. It can take years to guess passcode on a latest iPhone. 8. FBI wants unlimited way to do passcode guesses FBI wants to decipher information in the iPhone of San Bernardino's attacker. Apple has vowed to resist FBI demand to crack iPhone linked to San Bernardino attacks. Apple does not want to build a backdoor to the iPhone. 9.

Introduction to PKI and TLS - CloudFlare's Head of Cryptography Nick Sullivan
 
17:57
Nick Sullivan, Head of Cryptography at CloudFlare, gives a great introduction to PKI and TLS. Public key infrastructure (PKI) is a set of policies and procedures needed to create and manage digital certificates and public-key encryption. Transport Layer Security (TLS) is a protocol that encrypts communicates between applications and their users on the Internet. TLS prevents eavesdropping or tampering with the message by third parties.

Blockchain/Bitcoin for beginners 3: public/private keys, signatures... and first ever transaction
 
36:25
Detailed overview of public/private key encryption and live demo of exactly how digital signatures work on Mac, combining public and private keys and hash functions. Welcome to episode 3 of my series on Blockchain/Bitcoin. I'm joined once again by my girlfriend Nadisha who is my classroom pupil... I build on the hash function concepts from the previous episode and explain the basic concepts public and private keys and how to use them to create digital signatures - a key part of the bitcoin infrastructure. We demonstrate in a Mac terminal how you can generate your own keys and encrypt and decrypt and sign your own resources - learning by doing always works. We touch on bitcoin addresses, what they represent and how they are created. Finally I go back for a refresh of the bitcoin blockchain browser and look at the first ever bitcoin transaction in the "Genesis Block" to show what a real bitcoin address looks like. Bitcoin Blockchain browser https://blockchain.info Online hash calculator - great way to practice and familiarise with hash functions - one of the most important building blocks of Blockchain/Bitcoin http://www.fileformat.info/tool/hash.htm Course to date (previous videos) 1. Blockchain introduction https://youtu.be/xwA2TkcAQgQ 2. Hashing, blockchain networks and look at blockchain browser https://youtu.be/oxwMnqFNq9M SAMPLE COMMANDS: You will need to use your own document - pick any document, obviously your hash values will be different to mine. Also I had to use (right arrow) - since comments do not allow "chevron" symbols # EXAMPLE 1: # generate public and private keys openssl genrsa -out mykey 2048; cp mykey privatekey; openssl rsa -in mykey -pubout -out publickey; rm mike #encrypt with public key echo “the cat sat on the mat” | openssl rsautl -encrypt -pubin -inkey publicly (right arrow) cipher.txt # show the garbage cat cipher.txt # decrypt with private key - The cat sat on the mat cat cipher.txt | openssl rsautl -decrypt -inkey privately # EXAMPLE 2: Sign Alice in wonderland #check the SHA256 hash of the document to send - d9db7b8984d808b2821070cc6cc76e4415229d3356452b2a0f06ec3608f13b6c shasum -a 256 alice-in-wonderland.txt | cut -d" " -f1 # create a text file called signature which hashes the document and encrypts with private key shasum -a 256 alice-in-wonderland.txt | cut -d" " -f1 | openssl rsautl -inkey privatekey -sign (right arrow) signature # wrap the signature up with the public key, the document and the signature and send it … we just copy to another folder tar -cvf alice.tar signature alice-in-wonderland.txt publickey;mkdir -p inbox;cp alice.tar inbox;cd inbox;tar -xvf alice.tar # inspect the public key and verify with the sender that it belongs to the sender cat publickey #decrypt the signature with the received public key - d9db7b8984d808b2821070cc6cc76e4415229d3356452b2a0f06ec3608f13b6c openssl rsautl -inkey publickey -pubin -in signature # hash the received document - d9db7b8984d808b2821070cc6cc76e4415229d3356452b2a0f06ec3608f13b6c shasum -a 256 alice-in-wonderland.txt | cut -d" " -f1 # if they are both the same then the document cannot have been changed since it was signed by the genuine owner of the # private key corresponding to the public key

What is end-to-end encryption?
 
03:57
Much of the encryption that is performed online is so-called end-to-end encryption. End-to-end encryption means encryption and decryption are performed at the ends of the connection: on the client and server, or on both peers of a peer-to-peer connection. This is in contrast to link-layer encryption, where encryption is potentially performed only on one part of a connection—​such as a wireless link.

Asymmetric Encryption Lab Instructions
 
09:59
This video is part of a larger online course, "From Barter to Bitcoin: Society, Technology and the Future of Money" run by Prof. Bill Maurer and Prof. Donald J. Patterson In addition to the video on YouTube there is a variety of other content available to students enrolled in the class. "In 2008, a person calling himself or herself or themselves Satoshi Nakamoto released a paper suggesting a system for an anonymous, peer-to-peer alternative money. Bitcoin was born. Although not the first digital currency ever proposed, nor the first challenger to fiat money, bitcoin is the first to have captured the broad imagination of speculators, coders, regulators, criminals and the mass media. This course puts Bitcoin in context: how do we understand money as a social, political and technological phenomenon? From discussions of ancient transactions to the rise of state-issued currencies, we will explore the social and technical aspects of bitcoin, its predecessors and potential successors, and how its features echo aspects of many different historical transaction systems. No prior knowledge of economics or computing is required. There is little academic writing on bitcoin. And this may be the first truly academic class on the topic. We want to put bitcoin in a wider perspective, to reflect on what it means for society, politics and economics, as well as how it helps us think about money both a social and a technical phenomenon. This class is not an advanced seminar on bitcoin--we will not be delving deeply into the inner workings of the system, but instead providing a bird's-eye overview with enough technical detail for you to be able to put media stories, hype and hope around bitcoin in perspective. Similarly, this is not a class in monetary economics--we won't go too deeply into monetary theory or policy, the money supply, or inflation. Instead the class invites you to think more deeply about one of the oldest systems of technology on the planet, and most ubiquitous: money, whether coin, cash, credit card or cryptocurrency, we humans have been making money for most of the past 10,000 years. How we do so in the future is a question bitcoin just maybe helps us answer."
