WebIn cryptography, an S-box (substitution-box) is a basic component of symmetric key algorithms which performs substitution. In block ciphers, they are typically used to obscure the relationship between the key and the ciphertext, thus ensuring Shannon's property of confusion.Mathematically, an S-box is a vectorial Boolean function.. In general, an S-box … Web1.Message authentication is a mechanism or service used to verify the integrity of a message. t 2. Joseph Mauborgne proposed an improvement to the Vernam cipher that uses a random key that is as long as the message so that the key does not need to be repeated. The key is used to encrypt and decrypt a single message and then is discarded.
