Webb18 juli 2024 · Example 4.3. 2. The keyspace of the Vigenère cipher cryptosystem with a key length of ℓ is all sequences of ℓ letters in the alphabet; therefore, it has N ℓ elements, if the alphabet is of size N. If the precise key length is not known, but it is known to be less than or equal to some bound L ∈ N, then there are ∑ j = 1 L N j ...

We ask whether perfect ciphers exists, i.e., ciphers that can never be broken, even with after an unlimited time. Interestingly, we will see that these ideal ciphers exist and can be implemented in practice but they are, in fact, unpractical. switch submodule branch
