A first device uses a first runtime environment executing on the first device to transfer a code module to a second runtime environment executing on a second device. The code module is configured to execute within the second runtime environment and expose a function of the second device that is supported by the second runtime environment to the first device. The first device executes an application within the first runtime environment. The application remotely invokes the function of the second device via the transferred code module and the second runtime environment.

A migration service and module for software modules are disclosed. The migration service detects a security flaw in a first environment in which the software modules are running and migrates the software modules or part of the software modules from the first environment to a second environment when a security flaw is detected.

Migration service method and module for software modules

The invention relates to the field of data processing in a distributed environment, and more particularly control of movement of data and processes so as to achieve a protection that ensures that sensitive data and processes is not moved to untrusted domains. This is achieved by a method and apparatus for tagging of data with a trust level, comprising configuring a data analysis policy for mapping data elements to one of a number of trust levels; receiving a data flow; inspecting the data flow and identifying data elements to be tagged; for a data element to be tagged, analyzing the data element and mapping it to a trust level according to the data analysis policy; and adding the mapped trust level to the data element. This is further achieved by a method and apparatus for data protection, comprising: within a domain as defined by a boundary () within which controlled trust levels prevail, starting a service request with associated data to be processed; inspecting a trust level of the data; locating a processing unit (PU) having an associated trust level. Depending on the location of the processing unit within or without the domain, and on the trust level of the located processing unit relative to the trust level of the data, the data is sent out from the domain to the processing unit for processing; or sent to the processing unit configured inside the domain for processing; or the trust level of the data is downgraded to be equal or less than the trust level of the processing unit, and the downgraded data is sent out from the domain to the processing unit for processing.

A computing device supports distributed application execution by sending a code module to different remote devices that have different device-specific support for a platform-independent device function, and sending, to at least two of the different remote devices, a platform-independent message indicating an event has occurred in order to trigger each of the at least two of the different remote devices to autonomously select a device-specific function from a plurality of device-specific functions, and execute the different device-specific support for the platform-independent device function. Each of the at least two of the different remote devices comprises an output interface and triggering each of the at least two of the different remote devices to execute the different device-specific support comprises triggering each of the at least two of the different remote devices to use their output interface for outputting differently from each other.

Methods and apparatus for dynamic instruction set selection for producing an output parameter based on one or more available input parameters are presented. In an example method, a device selects, from different candidate instruction sets that are each configured to produce a same output parameter, an instruction set that requires one or more input parameters that are each available at the device. In addition, in the example method, the device obtains the output parameter by executing the selected instruction set using the input parameters required by that instruction set. In some examples where more than one candidate instruction sets could be selected based on the available input parameters, the device may select the highest-ranking instruction set for execution.
