Future Vision
Super Distributed Intelligence Ubiquitous Networking
Industry-Virtual line: Line organization according to individual product
-Channel Assembly: Product customization in logistics
-Recycling: Classification based on specification and used history
Transportation-Smart ways: Roads memorizing accidents and advising safety drive
-Smart cars: Cars cooperatively driving with each other to reduce accidents and improve traffic speed and density
e-Life(Human Body)-Wearable Tools: Digital fabrics, computer ring, and other information tools receive various services such as safety, entertainment, business, etc.
-Silicon Surgeons: Robots travel through body and monitor the health problem.
Home/Office-Borderless operation: Appliances accessible from everywhere
-Cooperative energy saving: Appliances autonomously work together for peak power shift

Basic Concept
AYA: context-Aware & Yet Another service
綾 (AYA): A twill weave, a fabric with a twill weave
Towards the woven and twilled intelligence system– The warp = Connection between
Information and physical presence– The woof = Link between physical
presences [Nishijin brocade]

Target Application
Town Management Support System– Goal:
Area value augmentation Creating a real-world portal site attracting many
people to come, by using IT
– Requirements Service is highly situation-dependent
– Various users, events, timing, devices, … Service consistency support …and more…

Security Issue (1)
Easy come, easy go– Flexibility is likely to lead to fragility– The malicious user would easily realize the DoS
(Denial of Service) attack.– Even the normal users could interrupt the service
for another person.

Security Issue (2)
Ubiquitous direct access– The firewall cannot always be a premise in the ubi
comp environment.– Self-protection is needed. But, how?

Our first idea
Operation-Privilege (O.P.) Management– Remote Controller (RC) Metaphor– Device access is allowed after acquiring the RC.– Malicious access can be stopped by taking away
the RC.

Secure Tele-operation Protocol
Three-tier model approach– The secure procedure is arranged as the STP spec.

Ongoing works
Three-tier model is a firewall approach. Not suitable for ubiquitous direct access environment.
Some ongoing works– Embedded STP
Each active device would have the STP server functions for self-protection.
– Adapter dispatch approach O.P. mgt. with secure manager and adapter dispatch
– Privacy policy handling O.P. transfer vs. Privacy transfer
