Abstract
A system, method, and apparatus for a significant random number generator are disclosed. The method involves sensing, with a sensor on a spacecraft, a physical phenomenon. In one or more embodiments, the system utilizes a Lower Earth Orbiting (LEO) Iridium satellite for the spacecraft. The method further involves outputting, from the sensor, a value for the physical phenomenon. Also, the method involves inputting the value of the physical phenomenon into a pseudo-random number generator (PRNG). In addition, the method involves generating, with the PRNG, a sequence of random numbers using the value of the physical phenomenon as a seed for the PRNG. In some embodiments, the disclosed significant random number generator is employed by a spot beam based authentication system that is used to authenticate a claimant. In other embodiments, the disclosed significant random number generator is used for cryptology, routing network traffic, anti-jamming, certified time stamping, and secure identification applications.
