Abstract: A client module downloaded by web browser from a server receives authentication information to open a smart card in a card reader and to initiate a secure network connection to a first server module running on a server. The client module calls a second server module running on the server. And the client module receives a new application for the smart card. Then the client module causes the smart card to delete an old application and load the new application. Each of the operations performed by client module occurs in a single session.

Abstract: Disclosed herein are a system, non-transitory computer-readable medium, and method for confining content. A digital receipt is generated in response to a request for content. An identifier associated with the remote device sending the request is included in the digital receipt such that use of the content is confined to the remote device.

Abstract: A system and method are described for securing over the air communications between a service and a communication device. For example, one embodiment of a method for creating a security token on a communication device for communication between the communication device and a service includes combining a device identification of the communication device with a device capability to create a device information, the device capability known by the service. The method further includes encrypting the device information.

Abstract: A method and system is provided to secure a data transmission from a chip card to an off-card entity. A transport key is generated at the off-card entity. The transport key is transmitted in a secure manner from the off-card entity to the chip card. At the chip card, the transport key is used to encrypt data to be sent from the chip card to the off-card entity. The data having been encrypted at the chip card using the transport key is then transmitted from the chip card to the off-card entity. The off-card entity is capable of decrypting the data received from the chip card through use of the transport key previously generated at the off-card entity.

Abstract: One embodiment of the present invention provides a system that accesses a desired element during execution of a program. During operation, the system receives a reference to the desired element. The system determines if the reference is an internal reference to a location in a local package that is currently executing, or an external reference to a location in an external package. If the reference is an external reference, the system uses an index component of the reference to lookup an address for the desired element in a global reference table. Next, the system uses the address to access the desired element. Note that the address retrieved from the global reference table is larger than the reference, which allows the address to access a larger address space than is possible to access with the reference alone.
