Many WEP systems require a key in a relatively insecure format. What format is this?
- binary format.
- hexadecimal format.
- 128 bit format.
- 256 bit format.
- 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.
