“RUBIK'S CUBE” AS A TRANSPOSITION DEVICE
Douglas W. Mitchell · Cryptologia · 1992
This paper points out that the well-known “Rubik's Cube” can be used as a device for implementing a transposition cipher which is simple to operate and which should afford a high level of security. A particular system for using the cube is proposed. The system is secure against brute force attacks; since it permits a different scrambled ordering of letters for each letter block enciphered, it is also secure against multiple anagramming.
