About
QEYnet’s quantum key distribution network uses LEO microsatellites as dynamic Trusted Nodes to enable global, low-cost quantum-secured communication. Each satellite passes over any point on Earth approximately 15 times per day, using single-photon free-space optical links to exchange cryptographic keys between ground stations. Unlike fiber-optic QKD networks, which are limited to roughly 100 km before losses make transmission impossible, satellite QKD can link any two points on the planet without intermediate infrastructure, with the constellation scaling naturally with demand.
QKD provides unconditional security — mathematical proof that any eavesdropping attempt collapses the quantum state of the photons and is detectable by the communicating parties. This makes QEYnet’s network uniquely resistant to future quantum computers and to ‘harvest now, decrypt later’ data collection strategies, targeting financial institutions, governments, critical infrastructure, and any organization handling data whose value extends decades into the future.
