Cryptography Reference
In-Depth Information
Furthermore, we introduced the notion of redundancy of a (natural) language, as it is
often exploited when cryptanalysts try to attack an encryption system. Furthermore,
symmetric encryption systems are often analyzed using the key equivocation and
the unicity distance. If the unicity distance of a cipher is small, then relatively few
ciphertext bits are necessary to uniquely determine the key in use.
