GID Key

The GID-key (device group ID key) is the AES 256-bit key shared by all devices with the same application processor. This key differs between each SoC. (i.e. The S5L8900 has a different key from the S5L8930.)

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
