Prasann Kumar,Debjani Choudhuryalgebra. But now we will see that probability is also useful in cryptanalysis. In particular, we will see a method for breaking substitution ciphers that is fully automated. It won’t necessarily solve the cipher fully, but it will tend to get sufficiently close that fixing it at the end by hand will be very easy.
