Ticket-Based Spectrum Authorization And Access Control
View pageUS Patent:
20100070760, Mar 18, 2010
Filed:
Sep 12, 2008
Appl. No.:
12/209432
Inventors:
Michaela Vanderveen - Tracy CA, US
Lu Xiao - San Diego CA, US
Lu Xiao - San Diego CA, US
Assignee:
QUALCOMM Incorporated - San Diego CA
International Classification:
H04L 9/32
G06F 21/20
G06F 21/20
US Classification:
713156, 726 6, 380270
Abstract:
Aspects describe spectrum authorization, access control, and configuration parameters validation. Devices in an ad-hoc or peer-to-peer configuration can utilize a licensed spectrum if the devices are authorized to use the spectrum, which can be determined automatically. Aspects relate to distribution of authorization tickets by an authorization server as a result of validating a device's credentials and services to which the device is entitled. An exchange and verification of authorization tickets can be performed by devices as a condition for enabling a validated wireless link using the spectrum.

Appl. No.:
14/504659
Inventors:
- San Diego CA, US
Chong Uk Lee - Cupertino CA, US
Kamran Moallemi - Carlsbad CA, US

Abstract:
Various operations may be performed based on a distance-related function associated with two or more devices. For example, an association procedure for two or more devices may be based on one or more determined distances. Similarly, presence management may be based on one or more determined distances. A distance-related function may take various form including, for example, a distance between devices, two or more distances between devices, a rate of change in a relative distance between devices, relative acceleration between devices, or some combination of two or more of the these distance-related functions.

20150373035, Dec 24, 2015
Filed:
Jun 24, 2014
Appl. No.:
14/312939
Inventors:
- San Diego CA, US
Rajarshi Gupta - Sunnyvale CA, US
Lu Xiao - San Diego CA, US
Rajarshi Gupta - Sunnyvale CA, US
Lu Xiao - San Diego CA, US
International Classification:
H04L 29/06
Abstract:
A computing device may use machine learning techniques to determine the level, degree, and severity of its vulnerability to side channel attacks. The computing device may intelligently and selectively perform obfuscation operations (e.g., operations to raise the noise floor) to prevent side channel attacks based on the determined level, degree, or severity of its current vulnerability to such attacks. The computing device may also monitor the current level of natural obfuscation produced by the device, determining whether there is sufficient natural obfuscation to prevent a side channel attack during an ongoing critical activity, and perform the obfuscation operation during the ongoing critical activity and in response to determining that there is not sufficient natural obfuscation to adequately protect the computing device against side channel attacks.

20150373036, Dec 24, 2015
Filed:

Lu Xiao - San Diego CA, US
Rajarshi Gupta - Sunnyvale CA, US
Lu Xiao - San Diego CA, US
International Classification:
H04L 29/06
Abstract:
A computing device may use machine learning techniques to determine whether a side channel attack is underway and perform obfuscation operations (e.g., operations to raise the noise floor) or other similar operations to stop or prevent a detected side channel attack. The computing device may determine that a side channel attack is underway in response to determining that the computing device is in airplane mode, that the battery of the computing device the battery has been replaced with a stable DC power supply, that the touch-screen display of the computing device has been disconnected, that there are continuous calls to a cipher application programming interface (API) using the same cipher key, that there has been tampering with a behavioral analysis engine of the computing device, or any combination thereof.
