Simtec Electronics Entropy Key: USB True Random Number Generator
The Entropy Key is a small, unobtrusive and easily installed USB stick that generates high-quality random numbers, or entropy.
The Entropy Key contains two high-quality noise generators, and an ARM Cortex CPU that actively measures, checks and confirms all generated random numbers, before encrypting them and sending them to the server. It also actively detects attempts to corrupt or sway the device. It aims towards FIPS-140-2 Level 3 compliance with some elements of Level 4, including tamper-evidence, tamper-proofing, role-based authentication, and environmental attacks. If it detects that one of its two generators has failed, may be about to fail, or if it detects a physical attack, it will automatically shut down.
£36, but currently (Jan 2015) out of stock.
