    Abstract: Methods and systems are provided that use smartcards, such as subscriber identity module (SIM) cards to provide secure functions for a mobile client. One embodiment of the invention provides a mobile communication network system that includes a mobile network, a mobile terminal, a server coupled to the mobile terminal via the mobile network, and a subscriber identity module (SIM) card coupled to the mobile terminal. The SIM card includes a first key and a second key. The first key is used to authenticate an intended user of the mobile terminal to the mobile network. Upon successful authentication of the intended user to the mobile network, the mobile terminal downloads a function offered from the server through the mobile network. The second key is then used by the mobile terminal to authenticate the intended user to the downloaded function so that the intended user can utilize the function.

    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.

    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.
