Many WEP systems require a key in a relatively insecure format. What format is this?

A.
binary format.

B.
hexadecimal format.

C.
128 bit format.

D.
256 bit format.

E.
None of the choices.

Explanation:
As part of the IEEE 802.11 standard ratified in September 1999, WEP uses the stream cipher RC4 for
confidentiality and the CRC-32 checksum for integrity.
Many WEP systems require a key in hexadecimal format. If one chooses keys that spell words in the limited 0-
9, A-F hex character set, these keys can be easily guessed.
