Abstract
Method and system of secured direct link set-up (DLS) for wireless networks. In accordance with aspects of the method, techniques are disclosed for setting up computationally secure direct links between stations in a wireless network in a manner that is computationally secure. A direct link comprising a new communication session is set up between first and second stations in a wireless local area network (WLAN) hosted by an access point (AP), the direct link comprising a new communication session. The AP generates a unique session key for the new communication session and transfers secured copies of the session key to each of the first and second stations in a manner under which only the first and second stations can obtain the session key. A security mechanism is then implemented on the unsecured direct link to secure the direct link between the first and second stations using a secure session key derived from the session key.
