on it, such as crypt-
analysis. He has thus made possible, for the first time, a fundamental
understanding of the process of cryptogram solution.
From this insight flow several corollaries. It follows that the lower the
redundancy, the more difficult it is to solve a cryptogram. Shannon's own
two extremes of redundancy illustrate this. The last few words of
Finnegans Wake are these: "End here. Us then. Finn, against! Take.
Bussoftlee, mememormee! Till thousendsthee. Lps. The keys to. Given! A
way a lone a last a loved a long the." This would interpose distinctly more
difficulties to a cryptanalyst than a portion of the New Testament in
Basic English: "And the disciples were full of wonder at his words. But
Jesus said to them again, Children, how hard it is for those who put faith
in wealth to come into the kingdom of God!"
The problem of low redundancy arises in practice with a vengeance
