Thermal and power fluctuations are common approaches to subverting the |
| 9 |
entropy available in an RNG. Thermal noise based entropy generators |
| 10 |
are particularly sensitive to this - reduce the temperature, reduce |
| 11 |
the entropy. IIRC, the VIA RNG is based on a pair of thermal sensors, |
| 12 |
but since they're on-die it's regarded more as difficult to subvert |
| 13 |
than an external set. |
