ComLac
The project ComLac was a 2019 winner of the PREMATURATION call for projects, led by the Innovation Lab of IP Paris.
THE PROBLEM ADDRESSED
Recent improvement in computational power created the need for more data-security. ComLaC proposes a complete system achieving both data encryption and transmis-sion in free-space using mid-infrared lasers. The solution is more secure than existing technology based on noise while remaining easier and cheaper to deploy than those using quantum cryptography.
TECHNOLOGY
Module for free space communication, secured by photonic chaos operating in the thermal atmospheric medium.
Uses quantum cascade technologies (ex. lasers & detectors) physically paired before deployment.
Targeted at real-time continuous information exchanges (possible code cracking would at best take several hours)
Technology fully extendable to fiber optic systems
