Looks to be "Software" related tied to bit sets via boot up as they are different per SRAM and associated with a certificate? I believe EDIG is more secure as with any software algrothim such as this, it can be hacked. Software is not the long term solution. I could see someone develop a systemactic routine to eventually identify the 1, 0 bit relationships. They are not infinite.

Edig Stands alone. They have the ultimate level. IMO
