  • Cryptographic systems and methods for extending apparent size of pools of truly random numbers
    Patent number: 11924328
    Abstract: A first copy of a True Random Number (TRN) pool comprising key data of truly random numbers in a pool of files may be stored on a sender and a second copy of the TRN pool is stored on a receiver. An apparent size of the TRN pool on each device is expanded using a randomizing process for selecting and re-using the key data from the files to produce transmit key data from the first copy and receive key data from the second copy.

  • Refractive/reflective optical element multiple beam spacer
    Patent number: 6400512
    Abstract: A six sided refractive / reflective optical element controls the separation between four parallel laser beams. Two beams will be reflected off the optical element and two beams will be refracted within the optical element with each reflection and refraction being off a different side of the optical element to form four closely spaced parallel light beams.
