Question #: 11
Topic #: 2

In the basic 4-way handshake used in secure 802.11 networks, what is the purpose of the ANonce and SNonce? (Choose 2)

AThey are used to pad Message 1 and Message 2 so each frame contains the same number of bytes.

BThe IEEE 802.11 standard requires that all encrypted frames contain a nonce to serve as a Message Integrity Check (MIC).

CThey are added together and used as the GMK, from which the GTK is derived.

DThey are input values used in the derivation of the Pairwise Transient Key.
