Not sure if memorizing a 6x6 matrix and computing that password in one's head is very efficient.
Also, shouldn't there be standard encryption schemes for doing stuff in your head? That homemade matrix encryption is probably not very hard to break.
- dfox 11y agoSchemes involving lookups into some reasonably sized random table/matrix are probably the most secure thing that is practical with only your head or only pen and paper. Similar system is/was used by various armed forces for both authentication and encryption of short messages (with the matrices being larger and rotated pretty often and thus not memorized).
