GID Key

The GID-key is the AES key shared by all devices with the same application processor. This key differs between devices with the S5L8900-based devices and S5L8930-based devices and higher.

It was used to generate Key 0x837.

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
