Noisy Diode entropy source

The Cryptech project is using Avalanche Noise as a physical entropy source connected to the FPGA.

Avalanche breakdown is a physical process that occurs when current is forced backwards through a diode until it cannot hold back anymore. The diode will then begin conducting for a brief time until the …

PKCS11 Proxy

The pkcs11-proxy is a way to tunnel PKCS11 over TCP (TLS). This page explains how to build and install PKCS11 proxy on the novena. There are various forks of this on github. We're going to use the SUNET fork since it support TLS-PSK for authentication out of the box. The …

Side Channel Attacks

Side Channel attacks on hardware are hard to avoid, detect and mitigate. But this should not stop us from trying. The CrypTech platform should be developed with side channel issues in mind. This page tries to collect information about relevant side channel attacks, mitigation strategies, side channel resistant design methods …
