Whether it’s a game of D&D or encrypting top-secret information, a wide array of methods are available for generating the needed random numbers with high enough entropy for their use case. For a ...

Sometimes you need random numbers — and properly random ones, at that. Hackaday Alum [Sean Boyce] whipped up a rig that serves up just that, tasty random bytes delivered fresh over MQTT. [Sean] tells ...

The world’s first practical quantum random number generator (QRNG) will reportedly overcome weaknesses of current encryption, revolutionizing internet security. The true randomness of numbers from ...

Random number sequences are essential to a host of encryption schemes. But true randomness in the strict sense is not possible in the classical world; it only occurs in quantum-mechanical processes.

In September 2013, whistleblower Edward Snowden revealed that American and British intelligence agencies had successfully cracked much of the online encryption internet users used to keep their ...

Researchers from the University of Geneva have reported on how the CMOS image sensors used within a mobile phone can be used as a quantum random number generator (QRNG). QRNGs are used to improve ...
