What is a Round Cipher?
A round cipher is a category of encryption structures that work with data portions of a fixed size at a certain number of rounds, which alter the data pieces through elementary substitution, permutation, and mixing stages. So the goal is to transform readable data (plaintext) into arbitrary data which is not so easy for anyone to understand (ciphertext) to maintain the security of data.
What is Round Cipher?
Round ciphers are also known as block ciphers, and they are a classification of encryption algorithms that work systematically, converting the plaintext into ciphertext. These algorithms work on a limited number of bits at a time and subject them to a set of mathematical processes called rounds which are used to bring about the act of encryption. It continually becomes progressively more rigid to attack the data without the correct key, each round is added to the security of the data. These are the operation sequences of a round that include substitution, permutation, key mixing, and input data.
