Abstract
Systems and techniques for secure communications and distribution of random values, provided via satellite communications, are described. These random values are generated from one or more ground-based entropy sources (e.g., quantum random number generators (QRNGs) at terrestrial locations), and optionally combined with values from satellite-based entropy sources (e.g., QRNGs at non-terrestrial locations). An example method includes: receiving a first random value generated by a first QRNG at a terrestrial location; receiving a second random value and a third random value via at least one satellite communication, each additional random value generated by other QRNGs; and generating a cryptographic key based on the first random value, the second random value, and the third random value. The cryptographic key may be produced by a key derivation function that combines the random values, and the cryptographic key may be used to establish a secure communication session.
