Publication number: 20140310782Abstract: 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.Type: ApplicationFiled: June 24, 2014Publication date: October 16, 2014Inventors: Michaela Vanderveen, Lu Xiao

Patent number: 8837724Abstract: Device authentication is based on the ability of a human to synchronize the movements of his or her fingers. A pairing procedure for two wireless devices may thus involve a synchronization test that is based on the relative timing of actuations of input devices on each of the wireless devices. In some aspects a synchronization test involves determining whether actuations of user input devices on two different wireless devices occurred within a defined time interval. In some aspects a synchronization test involves comparing time intervals defined by multiple actuations of user input devices on two wireless devices.Type: GrantFiled: August 24, 2007Date of Patent: September 16, 2014Assignee: QUALCOMM IncorporatedInventors: Gregory Gordon Rose, Lu Xiao, David Jonathan Julian

Publication number: 20140258353Abstract: One feature pertains to a method that reduces the computational delay associated with generating prime numbers. The method includes generating a first random number having a plurality of bits. A first primality test is then executed on the first random number. Then, it is determined whether the first random number generated fails or passes the first primality test. If the first random number fails the primality test then a portion but not all of the plurality of bits of the first random number are replaced with an equal number of randomly generated bits to generate a second random number. Next, a primality test is again executed on the second random number. This process is repeated until a prime number is detected.Type: ApplicationFiled: March 8, 2013Publication date: September 11, 2014Applicant: Qualcomm IncorporatedInventors: Lu XIAO, Binjan Ansari

Patent number: 8788802Abstract: A constrained proxy key is used to secure communications between two devices via an intermediary device. A first proxy key is generated at a host device (key generator device) based on a shared secret key, one or more constraints on the first proxy key, and a key derivation function. At least the shared secret key and key derivation function are known to the host device an a client device (authentication device). The first proxy key is sent to a proxy device to use in authenticating communications with the client device. An authenticated message is generated by the proxy device using the first proxy key and sent to the client device. The client device locally generates a second proxy key using the key derivation function, one or more constraints, and the shared secret key for authenticating the proxy device. The proxy device is authenticated if the client device successfully accesses the authenticated message from the proxy device using the second proxy key.Type: GrantFiled: September 27, 2006Date of Patent: July 22, 2014Assignee: QUALCOMM IncorporatedInventors: Alexander Gantman, Tolga Yalcinkaya, Gregory Gordon Rose, Lu Xiao

Patent number: 8555063Abstract: Disclosed is a method for establishing a wireless link key between a remote device and a group device. In the method, the remote device obtains a group identifier from the group device, and determines whether the group device is associated with a group having a trust association with the remote device. When the group device is determined to be associated with a group having an established trust association with the remote device, the remote device forwards a link setup request to the group device for virtually pairing with the group device using the trust association to establish the wireless link key. When the group device is determined not to be associated with a group having an established trust association with the remote device, the remote device forwards a pairing request to the group device for pairing with the group device to establish the wireless link key.Type: GrantFiled: September 30, 2009Date of Patent: October 8, 2013Assignee: QUALCOMM IncorporatedInventors: Lu Xiao, Yong Jin Kim, Zhanfeng Jia, David Jonathan Julian

Patent number: 8407760Abstract: Disclosed is a method for transitioning access rights, in a remote station with role-based access control, for an unknown role having access rights defined by a central access control management module. In the method, a role capability table is maintained in the remote station specifying centrally-defined access rights of roles that are interpretable in the remote station. An access request associated with an unknown role that is not interpretable in the remote station is received. The access request includes a role transition list that relates the unknown role to other centrally-defined roles. At least one of the other centrally-defined roles is interpretable in the remote station. A role is selected, from the role transition list, that is interpretable in the remote station for interpreting the unknown role of the access request. Access is granted based on the access request associated with the unknown role using the access rights of the interpretable role selected from the role transition table.Type: GrantFiled: October 17, 2008Date of Patent: March 26, 2013Assignee: QUALCOMM IncorporatedInventors: Gregory Gordon Rose, Alexander Gantman, Lu Xiao

Patent number: 8387129Abstract: Disclosed is a method for verifying data packet integrity in a streaming-data channel. In the method, data packets are received from the streaming-data channel. Each data packet includes a data payload and a corresponding message integrity code. The received data packets are processed in a first processing mode, wherein the received data packets are forwarded to an application module before checking the integrity of the data packets using the respective message integrity codes. An integrity-check-failure measurement is generated for monitoring an integrity-check-failure rate in the first processing mode. If the integrity-check-failure measurement exceeds an integrity-check threshold, then the method transitions to a second processing mode. A received data packet is forwarded to the application module in the second processing mode only after passing the integrity check.Type: GrantFiled: June 9, 2008Date of Patent: February 26, 2013Assignee: QUALCOMM IncorporatedInventors: Gregory Gordon Rose, David Jonathan Julian, Lu Xiao
