Abstract:
1. A system for managing service mobility using an eXtensible Markup Language (XML) electronic signature, comprising: a mobility interface for stopping and storing an operation of a service being currently performed and moving the service upon receiving a service move request from an Open Service Gateway initiative (OSGi) framework when a user submits the service move request; a service serializer for, before the requested service is moved, serializing service state information and converting it into an XML form, which is attachable to an electronic signature; an XML security manager, using a processor, for creating an XML electronic signature for a Manifest file of a Java ARchive (JAR) file of a service bundle, attaching the serialized service state information to an object element of the XML electronic signature, wherein the XML electronic signature is created to record security information of the service bundle and the service state without interworking with a certification authority; and a service installer for transmitting the signed JAR file with the XML electronic signature to said OSGi framework that subsequently installs the requested service and sets service state information to support the service mobility management.
