Attack
It would be great to perform some sort of side channel attack on this to extract it:
- Quo Vadis Labs
- Fault attacks on secure chips: from glitch to flash (Part 1)
- Side-channel attacks: new directions and horizons (Part 2)
- Research project: developing new technology for efficient side-channel analysis
