Telemetry Cockpit Live Simulator
Target Objectives
- Trace logic flow and algorithm behavior step by step.
- Measure performance and complexity trade-offs.
- Experiment with structures and systems in a safe sandbox.
Framework: HTML5 / WebGLOpenLabs Sandbox
Theory & Core Foundations
The Diffie-Hellman Key Exchange revolutionized cryptography in 1976 by solving the key distribution problem. Using one-way modular exponentiation, two parties establish a shared secret over an open channel.
Mathematical Foundations
Based on the computational difficulty of the Discrete Logarithm Problem.
A \equiv g^a \pmod p, \quad B \equiv g^b \pmod p
S \equiv B^a \equiv A^b \equiv g^{ab} \pmod p
How The Simulation Works
Simulate handshakes live and adjust secret exponents to see keys calculate in real time.
