Singapore researchers unveil self-verifying random number chip that cannot be hacked
Researchers at the National University of Singapore developed a quantum random number generator chip that continuously verifies its own hardware integrity while generating unpredictable numbers.
Previous quantum random number generators relied on a trusted-device model, but this new chip eliminates that assumption by using a measurement-device-independent protocol.
The chip operates at room temperature on a single silicon chip and triggers an automatic shutdown if detector responses deviate from quantum theory predictions.
The current prototype produces 64 bits per second, though simulations suggest future versions could reach 68 megabits per second.
The research has undergone its first trial as part of NIST’s randomness beacon, offering a paradigm shift for sectors needing certified random numbers without trusting hardware.
