- The case of the 9 bit AES key
Several PDF implementations generate AES-256 keys from tiny state spaces (9 bits in MuPDF) or insecure timestamp-based randomness, enabling trivial key recovery.
- A Scientific Achievement That’s Totally Random
New research demonstrates that quantum physics can generate truly random numbers, overcoming the limitations of conventional computers in encryption systems.
