Namaskaar Dosto, maine is video mein aapse Digital Signatures ke baare mein baat ki hai, aap sabhi ne bahut baar inke baare mein suna hoga, daily life mein toh aap sabhi signatures ko use karte hai, but Digital Signatures ekdum alag concept hai aur kaafi important bhi hai. Mujhe umeed hai ki aapko Digital Signatures ke baare mein yeh video pasand aayega. Share, Support, Subscribe!!!

https://media.ccc.de/v/35c3-9596-no_evidence_of_communication_and_morality_in_protocols_off-the-record_protocol_version_4 OTRv4 is the newest version of the Off-The-Record protocol. It is a protocol where the newest academic research intertwines with real-world implementations. It is also one of the first protocols that comes from the global south which makes the political discussion around protocols an urgency. This newest versions also asks us to revisit our definitions around deniability (online and offline) and how important is it to the world. In this talk we will try to start a discussion around the importance of protocols, its political/moral foundations, the real-world implementation of academic ideas, the importance of securely implementing them, the definition of deniability in the current world and the design of OTRv4. As we know from past revelations, the Internet has become a place where any action is surveilled and recorded. In the light of this, the OTR protocol was created. But it was created long time ago. In the past years, there have been a increased work on cryptographic primitives, and privacy and security notions. But these thoughts have not been incorporated into projects. OTRv4 is the newest version of the Off-The-Record protocol, which tries to incorporate these new ideas. At the same time, OTRv4 is a protocol that challenges the common thinking around protocols as it comes from the global south, and takes moral questions into its design, as Rogaway tried to defined on his "The Moral Character of Cryptographic Work?" paper. Furthermore, OTRv4 tries to update the notion of deniability and why it is important for the world. Sofia Celi Jurre van Bergen https://fahrplan.events.ccc.de/congress/2018/Fahrplan/events/9596.html

https://8gwifi.org/CipherFunctions.jsp Reference book: http://leanpub.com/crypto Cryptographic Algorithms generally fall into one of two different categories, or are a combination of both. Symmetric Fast Only provide confidentiality Examples: DES, AES, Blowfish, RC4, RC5 Asymmetric Large mathematical operations make it slower than symmetric algorithms No need for out of band key distribution (public keys are public!) Scales better since only a single key pair needed per individual Can provide authentication and nonrepudiation Examples: RSA, El Gamal, ECC, Diffie-Hellman problem with symmetric key cryptography DES (Data Encryption Standard) 64 bit key that is effectively 56 bits in strength Actual algorithm is called DEA (Data Encryption Algorithm) DES Modes Electronic Code Book Cipher Block Chaining (most commonly used for general purpose encryption) Cipher Feedback Output Feedback Counter Mode (used in IPSec) 3DES 112-bit effective key length Uses either 2 or 3 different smaller keys in one of several modes Modes EEE2/3 EDE2/3 AES NIST replaced DES in 1997 with this Uses the Rijndael algorithm Supports key/block sizes of 128, 192, and 256 bits Uses 10/12/14 rounds as block size increases IDEA (International Data Encryption Algorithm) Operates on 64 bit blocks in 8 rounds with 128 bit key Considered stronger than DES and is used in PGP Blowfish 64 bit block cipher with up to 448 bit key and 16 rounds Designed by Bruce Schneier RC4 Stream cipher with variable key size created by Ron Rivest RC5 Another Rivest cipher Block cipher with 32/64/128 bit blocks and keys up to 2048 bits RC6 Beefier version of RC5 submitted as AES candidate CAST 64 bit block cipher with keys between 40-128 bits with 12-16 rounds depending on key length CAST-256 used 128-bit blocks and keys from 128-256 bits using 48 rounds SAFER (Secure and Fast Encryption Routine) Set of patent-free algorithms in 64 and 128 bit block variants Variation used in Bluetooth Twofish Adapted version of Blowfish with 128 bit blocks, 128-256 bit keys and 16 rounds AES Finalist Kryptografie mit symmetrischem Schlüssel symmetric key cryptography symmetric key cryptography tutorial symmetric key cryptography example symmetric key cryptography vs asymmetric key cryptography symmetric and asymmetric key cryptography symmetric key cryptography Kryptografie mit symmetrischem Schlüssel Kryptographie mit symmetrischem Schlüssel Kryptographie mit symmetrischem Schlüssel Kryptografie mit symmetrischem Schlüssel und asymmetrische Schlüsselkryptographie symmetrische und asymmetrische Schlüsselkryptographie Kryptografie mit symmetrischem Schlüssel

Speaker: Brenno de Winter Shaping a digital future with ancient wisdom For many people cryptography is something that they consider too complicated. But actually one can understand the principles very well if they only try. By looking at old handcyphers used for coding one can begin to understand modern cryptography.

Join Aaron Carpenter and Nate Derbinsky in this WITx Talk! Traditionally, security algorithms rely on random, but deterministic algorithms created in software. Unfortunately, random number generators are typically not truly random. This work explores the designs of Physical Unclonable Functions (PUFs), which provide hardware random numbers, leveraging the inherent manufacturing unpredictability for individual transistors. These circuits provide random numbers for cryptographic functions and digital signatures, skipping the software generation entirely. Meanwhile, in a growingly complicated and power-constrained microprocessor environment, large portions of the chip remain "dark" or without power.As much of the on-chip coach remains off at a given rime, we can repurpose portions as PUF circuits, creating a large array of random numbers for cryptographic functions.

RNG based on the HV/Counter board from my last video: https://www.youtube.com/watch?v=mNKmLJm7O_g Now using a ATmega644p because the S-Boxes wouldn't fit into the RAM of the small one. Whenever a particle is detected a random number is generated (20-200 a minute). A block cipher is used in a loop to increase the output. Bytes in the s-boxes are swapped and ciphertext+key are modified when a particle is detected. Outputs nothing but a stream of bytes to the serial port, a FT232 serial to USB cable helps getting the bytes to a computer. Passes all diehard and dieharder tests. Sample file uploaded to http://www.cacert.at/cgi-bin/rngresults as "SBM20test".
