Abstract

Future computers will be integrated in objects of everyday life. The number of processors in the environment will increase and data will be distributed over different nodes. New classes of information and devices will appear, i.e. data will be catched from environmental sensors and will be used for context extraction. The amount of new devices and services makes an efficient use by centralized systems very difficult.Mobile agents provide an eminent method by virtualizing the user and performing actions on her behalf. They offer a possibility to encapsulate information of a person and her preferences, likings, and habits and perform location-based services of the ubiquitous system in the name of the user. This paper presents a mobile agent system application, where a mobile user-agent follows the user while she moves in the physical space. The user-agent knows personal information and communicates with service-agents in the name of its user to perform special tasks. Because of the personal data security and privacy are major concerns of such an agent system. The paper describes the communication of agents and agent nodes and focuses on the security extensions required by this approach
