Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a STA. The STA communicating with a first AP based on a key. The STA receives an identifier broadcasted from a second AP. The STA determines whether the key can be used with the second AP based on the received identifier.

The key may be a PTK. The PTK may be a function of the identifier. The identifier may be a zone identifier identifying a set of APs that belong to a security domain in which the association context information of the STA can be transferred from one AP to another AP.
