Which of the following is not a property of the Rijndael block cipher algorithm?

A.
It employs a round transformation that is comprised of three layers of distinct and invertible transformations.

B.
It is suited for high speed chips with no area restrictions.

C.
It operates on 64-bit plaintext blocks and uses a 128 bit key.

D.
It could be used on a smart card.

Explanation:
This option is incorrect because the block sizes supported by Rijndael are 128, 192, and 256 bits.
Incorrect Answers:
A: Rijndael is a substitution linear transformation cipher that uses triple discreet invertible uniform
transformations.
B, D: The Advanced Encryption Standard (AES), also known as Rijndael, performs well on a wide variety of
hardware. Hardware ranges from 8-bit smart cards to high-performance computers.
