Which of the following statements about a stream cipher are true? Each correct answer represents
a complete solution. Choose three.

A.
It typically executes at a higher speed than a block cipher.

B.
It divides a message into blocks for processing.

C.
It typically executes at a slower speed than a block cipher.

D.
It divides a message into bits for processing.

E.
It is a symmetric key cipher.

Explanation:
A stream cipher is a symmetric key cipher or encryption. It divides a message into bits
for processing. It typically executes at a higher speed
than a block cipher. A stream cipher is also known as a state cipher, as the encryption of each digit is
dependent on the current state.
