[Cryptography] XOR linked list & crypto

[Henry Baker]

A famous XOR hack (Knuth??) enables traversing a list in either direction:

https://en.wikipedia.org/wiki/Xor_linked_list

Of course, you need *two* successive pointers in order to access the list.

"Features" "Given only one list item, one cannot immediately obtain the addresses of the other elements of the list"

"Drawbacks" "The pointers will be unreadable if one isn't traversing the list"

Yes, this inability is used as both a "feature" and as a "drawback".

Q: Have these features/drawbacks been used in any encryption scheme?

Thanks for any pointers(!) or references(!) to published work.
