Patent number: 10356670Abstract: 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.Type: GrantFiled: April 5, 2017Date of Patent: July 16, 2019Assignee: QUALCOMM IncorporatedInventors: David William Craig, Gavin Bernard Horn, Anand Palanigounder, Arnaud Meylan

Publication number: 20180357183Abstract: A container from a first root of trust associated with a first root entity may be received. The container may correspond to a mapping of a resource of an integrated circuit that is associated with the first root entity. The container may be verified based on a key that corresponds to the first root of trust and that is stored in the integrated circuit at manufacturing of the integrated circuit. An identification may be made that an assignment of the resource from the container corresponds to assigning the resource from the first root of trust to a new root of trust. A new key corresponding to the new root of trust may be generated. Information corresponding to the new key may be stored into a memory of the integrated circuit. Furthermore, the new key may be used to delegate the resource to a subsequent container.Type: ApplicationFiled: December 1, 2016Publication date: December 13, 2018Inventors: Ambuj KUMAR, William Craig RAWLINGS
