Webb13 juli 2024 · How would Shannon’s entropy (H) be applied if for example an English text prior to encryption has undergone a transformation into a random string of characters. Let’s assume a Markov process, generating for each plaintext character a random permutation and the character mapped against the permutation – m → tm. WebbTo show Shannon’s entropy is the only expression that satisfy these three conditions, we design a special compound experiment. Consider an experiment in which we randomly …
