Improvements in Security and Code Migration Related Core System Functionality for Mobile Agent System AgentSphere

We at the software laboratory at Seikei University are developing a platform that enables parallel and distributed processing in an autonomous manner. This platform is called AgentSphere and one of its main traits is a strong code migration which henceforth shall be referred to as "Strong Migration". Through this migration, autonomous code which is referred to as "Agent" migrate between the platform while retaining its previous run state. In this paper, we talk about two main improvements to this system. First, the current serialization was using unoptimized java serialization which was slow and had overhead. We solve this problem by implementing a customizable serializer which serializes in Json format and is much faster than the default one. Second, we close off security gaps created by the unorthodox usage of our Strong Migration which accepts unknown classes and deserializes them inside the runtime
