ISSC680 Wk3.docx ISSC680 Week 3 Homework ISSC680 Week 3 Homework Cryptographic algorithms come in a variety of forms, but they all serve the same basic function; to provide a sequence of instruc... tions in order to encrypt or decrypt sets of data. This is done in an effort to ensure it is difficult for unauthorized third parties to read the information being sent across the various transmission media. One of the more well-known cryptographic algorithms is the Advanced Encryption Standard, more often referred to simply as AES. AES œis an iterative block cipher based on substitutions and permutations  (Peltier, 2013, p. 34) and uses key lengths of 128, 192, or the more standard 256 bits. Every increase in key length adds to the complexity of the cipher due to the amount of possible combinations. A single change in the input data can result in multiple changes in the output encrypted data.
