Diffie–Hellman, DLP & ElGamal Explained in 8 Minutes

Описание: In this video, we break down three of the most important concepts in modern public-key cryptography: Diffie–Hellman Key Exchange (DHKE), the Discrete Logarithm Problem (DLP), and the ElGamal Encryption Scheme.

🔐 What You’ll Learn (Brief Overview):
• How Diffie–Hellman lets two parties create a shared secret over an insecure network
• Why the security of DH relies on the Discrete Logarithm Problem (DLP)
• What the DLP actually is and why it’s considered computationally hard
• How ElGamal encryption extends Diffie–Hellman to encrypt real messages
• Why these systems require large prime numbers (1024–2048 bits) for long-term security
• How all three concepts form a cryptographic family based on the difficulty of discrete logs

This video gives you a fast, clear explanation of how these algorithms work, why they are secure, and where they’re used in modern cybersecurity (SSH, TLS, IPSec, and more).
