Satellite QRNG cryptographic key generation patent
Summary
The USPTO published patent application US20260095316A1 describing systems and techniques for secure communications using satellite-provided quantum random number values for cryptographic key generation. The invention enables generating cryptographic keys by receiving random values from quantum random number generators (QRNGs) via satellite communications and using specific key generation parameters to coordinate these values as seeds to cryptographic functions. Seven inventors are listed including Peter Bordow and Jeff Stapleton.
What changed
This patent application discloses a system for generating cryptographic keys using quantum random number generators (QRNGs) where at least one random value is provided via satellite communication. The method involves receiving first and second random values from QRNG sources, obtaining key generation parameters that specify a particular combination of these values, and generating a cryptographic key using that combination as a seed to a cryptographic function. The CPC classifications indicate H04L 9/0869 and H04L 9/0872, relating to key management security protocols.
Patent applications do not create compliance obligations or deadlines. For technology companies and telecommunications firms developing secure communications systems, this publication represents prior art that may affect freedom-to-operate analysis. No immediate action is required beyond awareness of the disclosed methodology for satellite-based quantum random number generation in cryptographic applications.

Abstract
Systems and techniques for secure communications and distribution of random values for cryptographic key generation, coordinated with the use of specific key generation parameters, are described. An example method includes: receiving a first random value and a second random value generated from at least one quantum random number generator (QRNG), with at least one of the first random value and the second random value being provided from a satellite communication; obtaining key generation parameters associated with cryptographic key generation, where the key generation parameters specify a specific combination of the first random value and the second random value; and generating a cryptographic key, using the specific combination of the first random value and the second random value, as a seed to a cryptographic function.
