  • Patent number: 8532571
    Abstract: A mobile device may be operable to determine, based on a known location of the mobile device, a location for a RF communication device that communicates with the mobile device, whenever the mobile device is within proximate range of the RF communication device. The determined location for the RF communication device may be stored in a location database in a location server and/or a memory in the RF communication device. The stored location of the RF communication device may then be used to determine a location for other mobile devices that may communicate with the RF communication device and are within proximate range of the RF communication device. The RF communication device may comprise a radio-frequency identification (RFID) device and/or a near field communication (NFC) device. The determined location for the RF communication device may comprise the known location of the mobile device.

  • Publication number: 20130230165
    Abstract: A method and system for secure and scalable key management for cryptographic processing of data is described herein. In the method, a General Purpose Cryptographic Engine (GPE) receives key material via a secure channel from a key server and stores the received Key encryption keys (KEKs) and/or plain text keys in a secure key cache. When a request is received from a host to cryptographically process a block of data, the requesting entity is authenticated using an authentication tag included in the request. The GPE retrieves a plaintext key or generate a plaintext using a KEK if the authentication is successful, cryptographically processes the data using the plaintext key and transmits the processed data. The system includes a key server that securely provides encrypted keys and/or key handles to a host and key encryption keys and/or plaintext keys to the GPE.

  • Patent number: 8521178
    Abstract: A multi-radio mobile device comprises a plurality of different radios. When a location update occurs, the multi-radio mobile device, at a specific location, acquires location-based radio information from a remote location server. The multi-radio mobile device selects a radio for use in the specific location based on the acquired location-based radio information comprising available radios in the specific location and radio weights. The radio is selected from the available radios based on the radio weights in the specific location. Transmissions of a desired service are received in the specific location utilizing the selected radio. Location-based radio measurements reports to the remote location server are generated utilizing signal strength measurements for the received signals. Radio quality information of the available radios is calculated by the location server utilizing location-based radio measurement reports from associated users.

  • Patent number: 8502396
    Abstract: Systems and methods for embedded tamper mesh protection are provided. The embedded tamper mesh includes a series of protection bond wires surrounding bond wires carrying sensitive signals. The protection bond wires are positioned to be vertically higher than the signal bond wires. The protection wires may be bonded to outer contacts on the substrate while the signal bond wires are bonded to inner contacts, thereby creating a bond wire cage around the signal wires. Methods and systems for providing package level protection are also provided. An exemplary secure package includes a substrate having multiple contacts surrounding a die disposed on an upper surface of the substrate. A mesh die including a series of mesh die pads is coupled to the upper surface of the die. Bond wires are coupled from the mesh die pads to contacts on the substrate thereby creating a bond wire cage surrounding the die.

  • Publication number: 20130129087
    Abstract: Methods and systems for secure key generation are provided. In embodiments, during the manufacturing process, a device generates a primary seed for the device and stores the seed within the device. The device exports the device primary key to a secure manufacturer server. The secure manufacturer server generates a public/private root key for the device and requests a certificate for the public root key of the device from a certificate authority. The device, having the stored primary seed, is integrated into an end-user system. Upon occurrence of a condition, the device after integration into the end-user system generates the public/private root key in the field. The system also receives and installs the certificate for the public root key.

  • Patent number: 8442015
    Abstract: Methods and systems for an atomizing function for a mobile device are disclosed and may include discovering available resources via a handheld wireless communication device (HWCD) and assessing respective cost functions for processing tasks by the HWCD and/or the discovered resources. The tasks may be apportioned for local and/or remote execution by the HWCD and/or the discovered resources based on the assessed cost functions. The assessed cost functions may be dependent on factors comprising communication bandwidth, memory space, CPU processing power, and battery power, which may be weighted. The cost functions may be dynamically assessed, enabling dynamic reapportioning of the tasks, which may be apportioned based on latency, quality of service (QoS), priority and/or user preferences associated with the local and/or remote execution. The apportioning of the processing of the tasks may be based on the assessed cost functions, and a priority and/or a QoS associated with the task.

  • Patent number: 8355706
    Abstract: A Wireless mobile communication (WMC) device may maintain user preference information, which is unique to the WMC device capabilities and the device user. The WMC device may modify and/or update the user preference information based on device use and information ascertained from applications running on the WMC device itself; for example scheduling applications. The user preference information may be utilized to create context data tags for generated data on the WMC device. Context data tags may comprise such information as time/date stamping, subject information, and/or location information. The context data tags may be utilized to tag the generated data, enabling continuous and improved cataloging. Improved cataloging may enable improved searchability of tagged data. Tagged data alternatively and/or additionally may be transferred and stored in a remote device for improved and secure back-up storage. The remote device may utilize context data tags for cataloging and storing received data.

  • Publication number: 20130010962
    Abstract: An authorized user may be provided access to a service only when a wireless token assigned to the user is in the proximity of a computing device. A user's credential may be stored on an RFID token and an RFID reader may be implemented within a security boundary on the computing device, Thus, the credential may be passed to the security boundary without passing through the computing device via software messages or applications. The security boundary may be provided, in part, by incorporating the RFID reader onto the same chip as a cryptographic processing component, Once the information is received by the RFID reader it may be encrypted within the chip. As a result, the information may never be presented in the clear outside of the chip. The cryptographic processing component may cryptographically encrypt/sign the credential received from the token.
