DERIVING A WLAN SECURITY CONTEXT FROM A WWAN SECURITY CONTEXT

摘要

Techniques for deriving a WLAN security context from an existing WWAN security context are provided. According to certain aspects, a user equipment (UE) establishes a secure connection with a wireless wide area network (WWAN). The UE may receive from the WWAN an indication of a wireless local area network (WLAN) for which to derive a security context. The UE then derives the security context for the WLAN, based on a security context for the WWAN obtained while establishing the secure connection with the WWAN and establishes a secure connection with the WLAN using the derived security context for the WLAN. This permits the UE to establish a Robust Security Network Association (RSNA) with the WLAN while avoiding lengthy authentication procedures with an AAA server, thus speeding up the association process.

主权项

1. A method for secure wireless communications by a user equipment (UE), comprising:
establishing a secure connection with a wireless wide area network (WWAN); deriving a security context for a wireless local area network (WLAN), based on a security context for the WWAN; and establishing a secure association with the WLAN using the derived security context for the WLAN.
