Post-Processing Free Spatio-Temporal Optical Random Number Generator   Resilient to Hardware Failure and Signal Injection Attacks
  We present a random number generator based on quantum effects in photonic emission and detection. It is unique in simultaneous use of both spatial and temporal quantum information contained in the system which makes it resilient to hardware failure and signal injection attacks. We show that its deviation from randomness cam be estimated based on simple measurements. Generated numbers pass NIST Statistical test suite without post-processing.
