Abstract: This disclosure relates to generating and sharing random data. A data port receives intensity data indicative of a measured intensity of electromagnetic radiation radiated from a rotating star over an observation time period. A processor transmits configuration data to a receiving device, which is indicative of an observation time period and an identification of the rotating star. The processor then identifies multiple pulses in the intensity data, each of the multiple pulses being associated with a pulse intensity value and generates the random data by generating multiple digital data values based on the pulse intensity value. The configuration data enables the receiving device to generate the random data. Transmitting the observation time period and the identification of the rotating star enables another device to generate the random data without receiving the random data directly, or to verify that received random data has not been tampered with.
