The scope of this document covers support for a method for generating and exchanging Session Key information between the access terminal and the access network. This air interface standard defines the Key Exchange Protocols for the cdma2000 high rate packet data air interface
The Generic Key Exchange Protocol performs the following functions:
• Proves that both access terminal and access network have the same Pairwise Master Key.
• Derives Session Key(s) from the Pairwise Master Key and nonces that are exchanged between the access network and access terminal.
• Protects against a man-in-the-middle attack where a rogue entity causes the access terminal and the access network to agree upon a weaker security protocol.
