Interesting take. Why cryptographic?
Discussion
Cryptographic only means that you can't guess one key from another .. means you can't know smell to memory relationship if you have only one .. plus the elliptical curve is different for every human ( actually every animal) ..
Crypto need not be a mathematical algo !
I just assume that cryptographic includes encryption and I don't think there is one when it comes to brain and associative memories? I might be wrong of course
You are going with Computer science definition .. the word existed long before CS :-) ..
Cryptic only means hard to decipher .. not impossible .. given enough time and effort, any cryptic message can be understood..
