KEK key encryption key, the key used to encrypt the traffic encryption key
MPDU MAC protocol data unit
MSK master session key
OFDM orthogonal frequency division multiplexing, a digital modulation scheme. It splits a bit stream into several sub streams, and transmits them in parallel by modulating orthogonal sub carrier frequencies
