Designing secure agents with O.O. technologies for user's mobility

摘要

Using differnet kinds of computers from different location has become a classical phenomenon. A user is said to be mobile when he does not always communicate with the outside from the same location. More and more people are being included in this category, such as people using a workstation linked to the Internet at their office, a microcomputer equipped with a telephone modem at home or a portable computer communicating via a wireless link. Features of these stations can be drastically differnet (GC94) especially for mobile computers due to numerous constraints such as weight, size, low communication flow and energy consumption (FZ94), (IV94). Communication with a mobile user depends on the terminal used. This paper proposes an agent-based system in which one agent is associated to one user in order to simplify his tasks. Object-oriented technologies will be used as a way to guarantee agent's data privacy, protect agent acceptor's sites from intrusions and, in case of loss, make agent's recovery easier to perform.
