Cryptography Full Course Part 1

💠💠ABOUT THIS COURSE💠💠 Cryptography is an indispensable tool for protecting information in computer systems. In this course you will learn the inner workings of cryptographic systems and how to correctly use them in real-world applications. The course begins with a detailed discussion of how two parties who have a shared secret key can communicate securely when a powerful adversary eavesdrops and tampers with traffic. We will examine many deployed protocols and analyze mistakes in existing systems. The second half of the course discusses public-key techniques that let two parties generate a shared secret key. Throughout the course participants will be exposed to many exciting open problems in the field and work on fun (optional) programming projects. In a second course (Crypto II) we will cover more advanced cryptographic tasks such as zero-knowledge, privacy mechanisms, and other forms of encryption. 🔥Course material🔥 ▶▶ https://drive.google.com/file/d/1Oy3Vr_aL0vaT1M9NOcPwJriHB512k42V/view?usp=sharing ♥️♥️Recommended Reading♥️♥️ ▶▶The Code Book: The Science of Secrecy from Ancient Egypt to Quantum Cryptography https://amzn.to/3vz1Rza ▶▶The Code Breaker https://amzn.to/3e7ua1N ⭐⭐⭐⭐🕑TIME STAMP📋⭐⭐⭐⭐⭐ 👉INTRODUCTION 0:00:00 Course Overview 0:10:34 what is Cryptography 0:26:26 History of Cryptography 0:45:16 Discrete Probability (Crash Course) ( part 1 ) 1:03:23 Discrete Probability (crash Course) (part 2) 👉STREAM CIPHERS 1:17:13 information theoretic security and the one time pad 1:35:46 Stream Ciphers and pseudo random generators 1:55:34 Attacks on stream ciphers and the one time pad 2:18:48 Real-world stream ciphers 2:38:26 PRG Security Definitions 3:03:20 Semantic Security 3:18:51 Stream Ciphers are semantically Secure (optional) 👉BLOCK CIPHERS 3:29:46 skip this lecture (repeated) 4:02:25 What are block ciphers 4:19:10 The Data Encryption Standard 4:41:09 Exhaustive Search Attacks 5:00:51 More attacks on block ciphers 5:16:54 The AES block cipher 5:30:28 Block ciphers from PRGs 👉USING BLOCK CIPHERS 5:42:12 Review- PRPs and PRFs 5:53:43 Modes of operation- one time key 6:00:57 Security of many-time key 6:23:47 Modes of operation- many time key(CBC) 6:40:00 Modes of operation- many time key(CTR) 👉MESSAGE INTEGRITY 6:49:20 Message Authentication Codes 7:04:36 MACs Based on PRFs 7:14:34 CBC-MAC and NMAC 7:34:15 MAC Padding 7:42:55 PMAC and the Carter-wegman MAC 👉COLLISION RESISTANCE 7:58:21 Introduction 8:09:15 Generic birthday attack ✨✨PLEASE IGNORE THESE TAGS✨✨ #cryptographylectures What is cryptography, introduction to cryptography, cryptography for beginners, cryptography basics, cryptography and network security, encryption algorithms, encrypt, decrypt, encryption, decryption, public key cryptography, RSA algorithm, RSA cryptography, RSA encryption, cybersecurity for beginners, cyber security training for beginners, cyber security course, ------------------------------------------------------------------------------------------------------------------------------------- If you really enjoy my content, you're welcome to support me and my channel with a small donation via PayPal ⌨️ This course is created in collaboration with Stanford University. 👉Link to PayPal donation https://www.paypal.me/nerdslesson ♥️♥️Thanks for watching don't forget to like and Subscribe♥️♥️
