3. Mesh Network • Homogeneous Network • devices with the same profile • Heterogeneous Network • devices with different profiles. • The latter will be the majority in ad-hoc networking (in our view).

4. Heterogeneous Profiles • Impact on self-organization. • We want to use optimal connection in terms of the security use (and other use for that matter). • Quick Reconfiguration may be impacted. • (Figure: heterogeneous mesh.)

5. Importance of the Security in Mesh. • Security is important! • It is not too much to stress this point many times over. • It is so even in the case of mesh network. • Make no mistake about it. An advertising kiosk in a public place needs security, too! (note page 92, [2]), • Taking advantage of the best security feature of each node is important.

6. eTRON Architecture • eTRON stands for entity-TRON. [1] • PKI-based security architecture. • Support cryptographic algorithms in a flexible manner: algorithm-agnostic framework. • (Figure to be added.: eTRON )

7. Application of eTRON IC chip in mesh environment. • Ubiquitous Communicator (UC) Terminal. • A hand-held device with communication functions for UWB ad-hoc networking (and bluetooth, WCDMA, etc..) • eTRON + UC terminal => an ideal powerful fully-functional device for multi-hop network environment (we offer end-to-end authentication.)

8. eTRON + UC terminal in mesh • (Figure to be added.) • eTRON chip + UC terminal can • be used for key distribution. • Establish connection and act as coordinator by choosing best security profile available. (eTRON chip and UC terminal can offer all the profiles of 4b.)

9. Issues • Desirable to have MAC-level profile transfer (read) between devices. • Necessary for quick self &secure configuration.
