Cryptography Explained: Stream Ciphers, Block Ciphers & Modes of Operation
In this video, we explore the fundamental concepts of modern cryptography and encryption techniques. Topics covered include: • Stream ciphers and the One-Time Pad (OTP) • XOR operation in encryption • Block ciphers and block sizes • Modes of operation: Electronic Codebook (ECB) Cipher Block Chaining (CBC) Cipher Feedback (CFB) Output Feedback (OFB) Counter Mode (CTR) Galois Counter Mode (GCM) • Lightweight cryptography for IoT devices • Homomorphic encryption concepts • Summary comparison of encryption techniques This tutorial is ideal for computer science students, cybersecurity learners, and anyone preparing for exams or certifications related to cryptography and network security.
