  • 1. INTRODUCTION BACKGROUND XMPP EXTENDED PROTOCOLS PROJECT MILESTONES CONCLUSION Project Proposal The Internet of Things using XMPP ******** ************* ******** ******* April 23, 2014
  • 2. INTRODUCTION BACKGROUND XMPP EXTENDED PROTOCOLS PROJECT MILESTONES CONCLUSION TABLE OF CONTENTS I INTRODUCTION BACKGROUND Internet of Things (IoT) XMPP XMPP EXTENDED PROTOCOLS Base IoT Protocols Extra IoT Protocols PROJECT Research Question Implementation Tests MILESTONES Realistic Caffeine Adderall CONCLUSION
  • 3. INTRODUCTION BACKGROUND XMPP EXTENDED PROTOCOLS PROJECT MILESTONES CONCLUSION TABLE OF CONTENTS II Conclusion
  • 4. INTRODUCTION BACKGROUND XMPP EXTENDED PROTOCOLS PROJECT MILESTONES CONCLUSION IOT: DEFINITION “The Internet of Things represents a vision in which the Internet extends into the real world embracing everyday objects. Physical items are no longer disconnected from the virtual world, but can be controlled remotely and can act as physical access points.”[1]
  • 5. INTRODUCTION BACKGROUND XMPP EXTENDED PROTOCOLS PROJECT MILESTONES CONCLUSION IOT: PROBLEMS Lower Power Scalability Interoperability Rolling Updates Security
  • 6. INTRODUCTION BACKGROUND XMPP EXTENDED PROTOCOLS PROJECT MILESTONES CONCLUSION PROBLEM: LOW POWER Good batteries don’t exist yet Want any potential device to be able to connect to the network and stay connected Physically small like a wrist watch Limited battery space and mW hours with possibly infrequent charging like an umbrella
  • 7. INTRODUCTION BACKGROUND XMPP EXTENDED PROTOCOLS PROJECT MILESTONES CONCLUSION PROBLEM: SCALABILITY Expected every person is connected to the Internet Each person reasonable to have at least 5 devices connected to the Internet at any given time Needs to scale to Billions of devices Layer 1 - 3 needs to be able to handle number of active devices being routed and addressable IoT protocols need to be able to be inherently cache-able, distributable, and redundant
  • 8. INTRODUCTION BACKGROUND XMPP EXTENDED PROTOCOLS PROJECT MILESTONES CONCLUSION PROBLEM: INTEROPERABILITY Need to be able to communicate with functionally compatible protocols Protocol needs to work on tiny devices Agnostic of Layers 1-3
  • 9. INTRODUCTION BACKGROUND XMPP EXTENDED PROTOCOLS PROJECT MILESTONES CONCLUSION PROBLEM: ROLLING UPDATES Even harder to change once as widely adopted as IPv4 Infinite backwards compatibility shouldn’t be expected Goal having the same quality of service as mainframes with 0% downtime
  • 10. INTRODUCTION BACKGROUND XMPP EXTENDED PROTOCOLS PROJECT MILESTONES CONCLUSION PROBLEM: SECURITY Privacy Anonymity Robust protocol Fail close protocol Semantics of protocol need to be as simple as possible not Turing Comlete Protocol pushes for better coding practices if where-ever possible
  • 11. INTRODUCTION BACKGROUND XMPP EXTENDED PROTOCOLS PROJECT MILESTONES CONCLUSION XMPP Extensible Messaging and Presence Protocol Communications protocol for message-oriented middleware based on XML Core Features Channel Encryption Authentication Error Handling Communication primitives for messaging Network Availability Request-Response interactions
  • 12. INTRODUCTION BACKGROUND XMPP EXTENDED PROTOCOLS PROJECT MILESTONES CONCLUSION XMPP: PROTOCOL OVERVIEW 1. Determine IP and port to connect 2. Open TCP Connection 3. Open XML Stream over TCP (TLS Optional) 4. Authenticate using Simple Authentication and Security Layer (SASL) mechanism 5. Bind resource to the stream 6. Exchange XML Data 7. Close XML Stream and TCP Connection
  • 13. INTRODUCTION BACKGROUND XMPP EXTENDED PROTOCOLS PROJECT MILESTONES CONCLUSION XEP-0325: IOT CONTROL IoT requires all devices to have actuators Devices that can be controlled through the network and act as with outside world Example - Control door locks
  • 14. INTRODUCTION BACKGROUND XMPP EXTENDED PROTOCOLS PROJECT MILESTONES CONCLUSION XEP-0323: IOT SENSOR DATA Basic operations and data structures for sensor data communication Sensor networks contain many different architectures Temperature Sensor - Analog Value value with precision/physical unit Annoying censors on CSL doors - digital value (0 or 1) XEP 0323 is designed to be simple due to different architectures and scalability
  • 15. INTRODUCTION BACKGROUND XMPP EXTENDED PROTOCOLS PROJECT MILESTONES CONCLUSION XPE-0326: IOT CONCENTRATORS Used for concentrating management of a sub set of devices (usually sensors) to one point Devices will be of different makes and models XEP 0326 has a small set of reduced operations for basic maintenance and interoperability Set of devices can be Small connecting all the windows in a house Medium all of the locks at a business Large all the devices at a college campus Massive all of the sensors and actuators at a power plant Convenience Ability to work with massive quantities of entities Effective syncronization between interested parties
  • 16. INTRODUCTION BACKGROUND XMPP EXTENDED PROTOCOLS PROJECT MILESTONES CONCLUSION XPE-0324: IOT PROVISIONING Used for efficient management of access rights and privileges What things can read data from what other things, and what data User Control and privileges But wait! Not all sensors can provide a user interface to control privileges Distributed third party Provide rich user interface and configurable options Control communication and available content Relies on Sensor Data & Control XMPP Extensions Example- Only the owner of the car may tell the car to start
  • 17. INTRODUCTION BACKGROUND XMPP EXTENDED PROTOCOLS PROJECT MILESTONES CONCLUSION XEP-0347: DISCOVERY Used for secure installation, configuration, and connection of massive amounts of things Goal is for 0 configuration networking Trade off is simplicity vs security
  • 18. INTRODUCTION BACKGROUND XMPP EXTENDED PROTOCOLS PROJECT MILESTONES CONCLUSION RESEARCH QUESTION Does the existing XEP IoT protocols solve the the major problems of IoT?
  • 19. INTRODUCTION BACKGROUND XMPP EXTENDED PROTOCOLS PROJECT MILESTONES CONCLUSION XMPP IMPLEMENTATION Use existing XMPP base code Implement XEP 0325 - Control Implement XEP 0323 - Sensor Data Note: Protocols are experimental and were updated last week.
  • 20. INTRODUCTION BACKGROUND XMPP EXTENDED PROTOCOLS PROJECT MILESTONES CONCLUSION TEST BED NS-3 Form of WAN and LAN emulation (e.g. CORE)
  • 21. INTRODUCTION BACKGROUND XMPP EXTENDED PROTOCOLS PROJECT MILESTONES CONCLUSION SCALABILITY TESTS Test overhead of protocol for data Test how many devices can simultaneously be connected to one XMPP Server
  • 22. INTRODUCTION BACKGROUND XMPP EXTENDED PROTOCOLS PROJECT MILESTONES CONCLUSION SECURITY TESTS Test how identifiable a person/device is from plain text and TLS encryption Test where can privacy can be broken, most likely assuming compromised server or concentrator
  • 23. INTRODUCTION BACKGROUND XMPP EXTENDED PROTOCOLS PROJECT MILESTONES CONCLUSION REALISTIC: MILESTONE 1 Implement Sensor/Control XEPs Scalability no concentrators Security anonymity and privacy no concentrators
  • 24. INTRODUCTION BACKGROUND XMPP EXTENDED PROTOCOLS PROJECT MILESTONES CONCLUSION CAFFEINATED: MILESTONE 2 Implement Concentrator Test scalability improvements with concentrators Test Security with concentrators
  • 25. INTRODUCTION BACKGROUND XMPP EXTENDED PROTOCOLS PROJECT MILESTONES CONCLUSION CAFFEINATED: MILESTONE 3 Implement Provisioning Test Scalability what additional traffic added? Test Security what data is leaked by provisioning?
  • 26. INTRODUCTION BACKGROUND XMPP EXTENDED PROTOCOLS PROJECT MILESTONES CONCLUSION ADDERALL: MILESTONE 4 Implement Discovery Test Scalability what additional traffic added? Test Security what data is leaked by provisioning?
  • 27. INTRODUCTION BACKGROUND XMPP EXTENDED PROTOCOLS PROJECT MILESTONES CONCLUSION CONCLUSION Fin
  • 28. INTRODUCTION BACKGROUND XMPP EXTENDED PROTOCOLS PROJECT MILESTONES CONCLUSION COMMENTS & QUESTIONS What do you think?
