| Summary : Interface to the Trifid cipher
|
Description :
In classical cryptography, the trifid cipher is a cipher invented around
1901 by Felix Delastelle, which extends the concept of the bifid cipher to
a third dimension, allowing each symbol to be fractionated into 3 elements
instead of two.
While the bifid uses the Polybius square to turn each symbol into
coordinates on a 5x5 (or 6x6) square, the trifid turns them into
coordinates on a 3x3x3 cube.
As with the bifid, this is then combined with transposition to achieve
diffusion.
However a higher degree of diffusion is achieved because each output symbol
depends on 3 input symbols instead of two.
Thus the trifid was the first practical trigraphic substitution.
