Abstract
A system and method are provided for generating group encryption keys for a global group and a private group to encrypt wireless messages between an access point and a station. The private group key is based on a unique private group identifier. The global group key and the private group key are sent from the access point to one or more stations via an M3 message as part of a 4-way handshake or as part of a 2-way group key handshake. The global group key is used for encrypted broadcast or multicast messages with an entire group, whereas the private group key is used for encrypted broadcast or multicast messages with a private group that is a subset of the entire group.
