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. A time value can be sent from the key server to the client, allowing for secure revocation of keys. In addition, secure configuration messages can be sent to the security module.

Abstract translation: 安全模块集成在客户端计算机中的安全架构，其中客户端计算机包括不受信任的本地主机。 安全模块执行加密和解密算法，认证和公钥处理。 安全模块还包括用于密钥加密密钥和应用密钥的单独的密钥高速缓存。 安全模块还可以通过应用密钥高速缓存来连接密码加速器。 安全模块可以授权公钥和相关联的密钥服务器。 该公钥随后可用于授权其他密钥服务器。 任何授权的密钥服务器都可以使用其公钥来授权其他密钥服务器的公钥。 然后可以在客户端和任何这些密钥服务器之间发现安全认证的通信。 这种连接是通过在客户端和密钥服务器之间发生的安全握手过程创建的。 时间值可以从密钥服务器发送到客户端，允许安全地撤销密钥。 此外，可以将安全配置消息发送到安全模块。

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.

Abstract: A handheld wireless communication device (HWCD) establishes an ad hoc network comprising interconnected networks for a user. The HWCD gains access to content on a first device and controls communication of the content from the first device via the HWCD to a second device. The HWCD enables the second device to consume the content. The content may be streamed from the first device via the HWCD to the second device. The first device is a service provider network device or other network device. The access may be authenticated and/or secure. Secure access to the content is extended from the first device to the second device. The ad hoc network is configured and/or reconfigured until communication is complete. The HWCD comprises multiple wireless interfaces. The ad hoc network comprises a PAN, WLAN, WAN and/or cellular network. The HWCD may hand-off among base stations during communication of the content.

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.

Abstract: Methods and systems for a persistent request generated by a wireless device, executed remotely and output to configurable local resources are described and may include generating via a handheld wireless communication device (HWCD) a persistent request for a user that may be communicated to remote devices for execution and storage of results. The stored results may be received from local resources local which may be configured by the remote devices based on user preferences to deliver the stored results to the user. The stored results may be received by the user via the HWCD or another wireless communication device, and the identity of the user may be authenticated prior to receiving the stored results. The remote devices may discover the local resources based on the detection of the user logging into the network. User preferences may be stored in networked devices or may be stored in the HWCD.
