  • Publication number: 20140177441
    Abstract: Wireless mobile communication (WMC) devices located in operating proximity of each other may be enabled to form a mesh (ad hoc wireless) network. WMC devices in a mesh network may form a queuing system wherein each WMC device may store data forwarded to and/or from other WMC devices in the mesh network. Each WMC device in the mesh network may have different queuing capability based on a plurality of factors that may comprise internal factors such as processing, storage, power, and/or connectivity. The mesh network may comprise an internal addressing scheme that may enable utilization of the queuing system whether or not WMC devices in the mesh network are communicatively coupled to external networks.

  • Publication number: 20140156872
    Abstract: Systems and methods are provided that allow a secure processing system (SPS) to be implemented as a hard macro, thereby isolating the SPS from a peripheral processing system (PPS). The SPS and the PPS, combination, may form a secure element that can be used in conjunction with a host device and a connectivity device to allow the host device to engage in secure transactions, such as mobile payment over a near field communications (NFC) connection. As a result of the SPS being implemented as a hard macro isolated from the PPS, the SPS may be certified once, and re-used in other host devices without necessitating re-certification.

  • Patent number: 8713309
    Abstract: A security architecture in which a security module is integrated in a client machine, wherein the client machine includes a local host that is untrusted. The security module performs encryption and decryption algorithms, authentication, and public key processing. The security module also includes separate key caches for key encryption keys and application keys. A security module can also interface a cryptographic accelerator through an application key cache. The security module can authorize a public key and an associated key server. That public key can subsequently be used to authorize additional key servers. Any of the authorized key servers can use their public keys to authorize the public keys of additional key servers. Secure authenticated communications can then transpire between the client and any of these key servers. Such a connection is created by a secure handshake process that takes place between the client and the key server.

  • Publication number: 20140115324
    Abstract: Systems and methods for secure remote biometric authentication are provided. A network-based biometric authentication platform stores biometric templates for individuals which have been securely enrolled with the authentication platform. A plurality of sensor platforms separately establishes secure communications with the biometric authentication platform. The sensor platform can perform a biometric scan of an individual and generate a biometric authentication template. The sensor platform then requests biometric authentication of the individual by the biometric authentication platform via the established secure communications. The biometric authentication platform compares the generated biometric template to one or more of the enrolled biometric templates stored in memory at the biometric authentication platform. The result of the authentication is then communicated to the requesting sensor platform via the established secure communications.

  • Publication number: 20140112196
    Abstract: A Wireless mobile communication (WMC) device may maintain user preference information, which is unique to the WMC device capabilities and the device user. WMC devices located in near proximity of each other may be enabled to form an ad hoc wireless network wherein each WMC device within the network may function as a router for other devices. Utilizing such routing capability within an ad hoc wireless network may allow WMC devices that are out of their wireless coverage area to use other WMC devices within such ad hoc wireless network to route any impending communication through such other WMC devices wherein these devices may have wireless connectivity to their coverage networks. WMC devices that are may have external connectivity may be enable to be selective in routing information and/or data from other WMC devices in the ad hoc network.

  • Patent number: 8689290
    Abstract: Systems and methods for securing a credential generated by or stored in an authentication token during an attempt to access a service, application, or resource are provided. A secure processor receives a credential from an authentication token and securely stores the credential. The secure processor then verifies the identity of the individual attempting to use the authentication token and cryptographically verifies the identity of the server being accessed. The credential is only released for transmission to the server if both the identity of the individual and the identity of the server are successfully verified. Alternatively, a secure connection is established between the secure processor and the server being accessed and a secure connection is established between the secure processor and a computing device. The establishment of the secure connections verifies the identity of the server. After the secure connections are established, the identity of the user is verified.
