Best answer

The statement, “In WEP, an initialization vector (IV) is sent in the clear in every frame”, is True.

Wired Equivalent Privacy (WEP) protocol is used to provide secure transmission between a wireless host and access point.

• The WEP protocol appends a 24-bit initialization vector (IV) to the 40-bit symmetric shared key (KS) to form a 64-bit key and uses this 64-bit key to encrypt the data frames.

• Since, each data frame is encrypted with different initialization vector (IV), the IV value is sent with plain text in each data frame.

• The receiver forms the 64-bit key by appending the IV to shared secret key (KS) and decrypts the data frame using this 64-bit key.
