    摘要: Embodiments of the present invention provide a system, method, and computer program product for updating software on an embedded computer device. According to one aspect of the present invention, a concurrent embedded application update is performed in which selected state information for one or both of an embedded virtual machine and a plurality of applets on an embedded computer device is securely exported to a host computer device. After software updates have been installed, the selected state information can be restored on the embedded computer device from which it was exported and/or it can be migrated to a second embedded computer device.

    摘要: A bytecode construction, a method, and a system for optimizing just in time compilation. The bytecode includes several regions wherein a region is a logical sequence of one or more bytecode blocks and the bytecode is annotated with region hints embedded therein. The region hints have a bytecode structure and are designed for instructing a just-in-time, or JIT, runtime environment for JIT compilation of the regions by JIT compilers implemented at nodes of a network. A method and a system for implementing the bytecode construction are also presented.

    摘要: Methods and apparatus are provided for authenticating communications between a user computer and a server via a data communications network. A security device has memory containing security data, and security logic to use the security data to generate an authentication response to an authentication message received from the server in use. An interface device communicates with the security device. The interface device has a receiver for receiving from the user computer an authentication output containing the authentication message sent by the server to the user computer in use, and interface logic adapted to extract the authentication message from the authentication output and to send the authentication message to the security device. Includes a communications interface for connecting to the server via a communications channel bypassing the user computer. Either the security device or interface device sends the authentication response to the server via the communications channel bypassing the user computer.

    摘要: A computer method, computer system, and article for enabling digital signature auditing. The method includes the steps of: receiving at least one signature request issued by at least one application, forwarding a first data corresponding to the received at least one signature request to at least one signing entity for subsequent signature of the first data, storing an updated system state that is computed using a function of: i) a reference system state and ii) a second data corresponding to the received at least one signature request, where the reference system state and the updated system state attest to the at least one signature request, and repeating the above steps, using the updated system state as a new reference system state, where the steps of the method are executed at a server of a computerized system.
