CitarAhmad explains it this way:
WPA2 uses two types of keys: 1) Pairwise Transient Key (PTK), which is unique to each client, for protecting unicast traffic; and 2) Group Temporal Key (GTK) to protect broadcast data sent to multiple clients in a network. PTKs can detect address spoofing and data forgery. "GTKs do not have this property," according to page 196 of the IEEE 802.11 standard.
