Invention:
This technology is a new type of cryptosystem that leverages atmospheric turbulence to protect free-space optical communication from eavesdropping.
Background:
Free-space optical (FSO) communication, the use of light as a communication method through the air, space, or water without the use of cables, is a promising communication method, particularly useful when traditional wires are cost-prohibitive or impractical. To improve the security of this communication method, cryptographic techniques such as quantum key distribution (QKD) or physical-layer security can be used to render FSO communication as secure or even more secure than wire-based communications.
This invention builds upon concepts from QKD and physical-layer security to create a cryptosystem that is faster than state-of-the-art alternatives while maintaining strong security and true randomness.
Applications:
- Optical communication networks
- 5G/6G communications
- Massive MIMO communications
- Defense
- Smart cities
Advantages:
- Cost effective
- Enables higher data rates than state of the art solutions
- Efficient
