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

20 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

21 Wearable Computing & Ubiquitous Computing Properties and Problems with Ubiquitous Computing Privacy issues Difficulty with personalized information: I am Tom ! Oh, its Tom Let me check my databse Oh, its Tom Let me check my databse Tom: Age: 25 Favorite Song: My heart will go on Tom: Age: 25 OK, let me check his OK, I will play this song Hi all, I am Mike, your new Boss My god, a new man! I have to update my database! Me Too! Its really troublesome!

22 Wearable Computing & Ubiquitous Computing Properties and Problem with Wearable Computing I am Tom ! Tom: Age: 25 Favorite Song: My heart will go on OK, let me check his OK, I will play this song

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

24 Wearable Computing & Ubiquitous Computing Properties and Problem with Wearable Computing Resource management: Oh my, What should I do? I am Tom ! Hi all, I am Mike Tom: Age: 25 Favorite Song: My heart will go on Mike: Age: 30 Favorite Song: Salvage Garden

25 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?

26 Wearable Computing & Ubiquitous Computing Reaping the best of both worlds
