As part of the IEEE 802.11 standard ratified in September 1999, WEP uses the CRC- 32
checksum for:

A.
integrity.

B.
validity.

C.
accuracy.

D.
confidentiality.

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.
