The Advanced Encryption Standard, the Rijndael cipher, can be described
as:

A.
A recursive, sequential cipher

B.
An iterated block cipher

C.
As treaming block cipher

D.
A Feistel network

Explanation:
The correct answer is “An iterated block cipher”. Answers A recursive, sequential cipher, A Feistel
network, and As treaming block cipher are distracters; however,
answer A Feistel network characterizes the Data Encryption Standard (DES) cipher.
