Lesson: [WIP] EV3 - Telegraph Machine: Key Exchange
Printer-friendly version
Overview:
This lesson shows students how to use Diffie-Hellman key exchange (using relatively small prime numbers). This lesson introduces a practical use for the modulo operation and prime numbers, and is a neat demonstration of mathematics applied to cryptography.
Objectives:
After completing this lesson, students should be able to:
- Describe how the Diffie-Hellman key exchange works in theory.
- Exchange a message with another group without the teacher being able to decrypt the message.
- Explain why the Diffie-Hellman key exchange is secure.
