Security Model in the Ambient

The Ambient Computational Environment (ACE) builds integrated rooms where services are integrated throughout the building. The services control the lights, projectors, cameras, etc all of which can be controlled by the users through their mobile desktops and with other non-traditional means such as talking to services. The following thesis describes the construction and security of the atomic objects within the environment. These atomic objects are called services in the architecture. The thesis describes communication mechanism that the services use, a secure form of the RMI protocol. It also discuses the use of the Transport Layer Security (TLS) for authorization, the use of TLS and Advanced Encryption Standard (AES) for data encryption and the use of Keynote Trust-Management system for distributing permissions to the services
