WebMar 2, 2024 · In cryptography, a block cipher is a deterministic algorithm operating on fixed-length groups of bits, called blocks, with an unvarying transformation that is specified by a symmetric key. Block ciphers are important elementary components in the design of many cryptographic protocols and are widely used to implement encryption of bulk data. WebA cipher should prevent an attacker, who has a copy of the cipher text but does not know the key, from discovering the contents of the message. Since we only have 26 choices for the key, someone can easily try all of the 26 keys, one by one, until they recover the message. This type of attack is called a brute force attack.
