  15. >>Wearable Computer Networking General requirements • Short-ranged • Simple in design • Low power consumption • Self-configuration • Restricted to the user • Security Security requirements • Privacy • Data Confidentiality • Data integrity • Access Control • Availability • Source Authentication

  16. >>Wearable Computer Networking BlueTooth Security>>Security Architecture

  17. >>Wearable Computer Networking BlueTooth Security>>Key Management PIN PIN E2 E2 Authentication Link Key Link Key E3 E3 Encryption Encryption Key Encryption Key Encryption and Key Control

  18. >>Wearable Computer Networking BlueTooth Security>>Authentication Verifier (User A) Verifier (User B) RAND SRES = E(key, IDB, RAND) SRES’ = E(key, IDB, RAND) SRES Checks:SRES’ = SRES Challenge-response for symmetric key system

  19. Wearable Computing & Ubiquitous Computing • Properties and Problems with Ubiquitous Computing • Privacy issues • Difficulty with personalized information: • Properties and Problem with Wearable Computing • Localized information: • Localized control • Resource management: • The Combination-Hive and Locust Swarm • A General Scenario

  20. Me Too! It’s really troublesome! Oh, it’s Tom Let me check my databse Oh, it’s Tom Let me check my databse OK, let me check his email OK, I will play this song My god, a new man! I have to update my database! Tom: Age: 25 Email: Tt@yahoo.com Tom: Age: 25 Favorite Song: My heart will go on Wearable Computing & Ubiquitous Computing Hi all, I am Mike, your new Boss • Properties and Problems with Ubiquitous Computing • Privacy issues • Difficulty with personalized information: I am Tom !

  21. Wearable Computing & Ubiquitous Computing Properties and Problem with Wearable Computing I am Tom ! OK, I will play this song Tom: Age: 25 Favorite Song: My heart will go on Email: Tt@yahoo.com OK, let me check his email

  22. Wearable Computing & Ubiquitous Computing Properties and Problem with Wearable Computing • 1. Localized information: • 2. Localized control I am Tom ! A New device! It should be added to my DB. Where is the printer’s driver? should I install it? Device Table: -------------------- 1.Computer 2.Recorder 3.Printer Device Table: -------------------- 1.Computer 2.Recorder

  23. Hi all, I am Mike I am Tom ! Tom: Age: 25 Favorite Song: My heart will go on Email: Tt@yahoo.com Mike: Age: 30 Favorite Song: Salvage Garden Email: Mm@yahoo.com Wearable Computing & Ubiquitous Computing Properties and Problem with Wearable Computing • Resource management: Oh my, What should I do?

  24. Wearable Computing & Ubiquitous Computing The Combination-Hive and Locust Swarm Why Hive? • Agents are Autonomous • Agents are proactive • Agents can interact • Agents can be mobile What is Locust Swarm?

  25. Wearable Computing & Ubiquitous Computing Reaping the best of both worlds
