Index of Coincidence
I'm new to the mailing list, but I have grep'd tcmay's CP-FAQ and all
related FAQs for this, but have yet to find anything.
I'm looking for detailed information on a statistical tool to aid in
cryptanalysis called an "index of coincidence". I would appreciate it if
someone could please explain what this is, how one builds such an index
against a given ciphertext, and how it is valuable in the cryptanalysis of
said ciphertext.
Many thanks,
Marc
