Security in migratory interactive web applications

In ubiquitous environments migratory interactive applications allow users to perform their tasks continuously across various devices. Users can push and pull migratory Web applications from one device to another for various reasons. However, the flexibility of such pervasive applications raises various security issues, such as the risk of theft of private information from the migrated user interfaces or the intrusion of malicious versions of the applications replacing the original ones. In this paper, we analyse such risks and present a number of solutions to address them in a client/server-based solution for supporting secure migration of interactive Web applications.
