  1. 1. 1 https://social.samsunginter.net/@rzrSamsung Open Source Group 2018 Build "Privacy by design" Webthings With IoT.js on TizenRT and more #MozFest, Privacy and Security track Ravensbourne University, London UK <2018-10-27> Philippe Coval <p.coval@samsung.com> Samsung Open Source Group / SRUK
  2. 2. 2 https://social.samsunginter.net/@rzrSamsung Open Source Group 2018 Hello world, $who am I ? ● Philippe Coval – Samsung Software engineer ● belongs to OpenSource Group ● member of SRUK team – based in Rennes, France ● Interests: – Libre Soft/Hard/ware communities – Embedded, IoT, Web, DIY… ● Need help? Find me online: – https://wiki.tizen.org/wiki/User:Pcoval
  3. 3. 3 https://social.samsunginter.net/@rzrSamsung Open Source Group 2018 Agenda ● Context: – IoT status, Privacy matters ! – Motivations for Web of Thing ● Mozilla Webthings framework ● Constrainted IoT devices – With Javascript ! – using webthing-iotjs ! ● Demos & Hands on session ● To be continued: – @ MozIoT booth – Privacy+Security space ● Level 9 – Online: ● irc://irc.mozilla.org/#iot
  4. 4. 4 https://social.samsunginter.net/@rzrSamsung Open Source Group 2018 IoT status ● The Internet of Things is a system of physical objects – that can be discovered, monitored, controlled, – or interacted with by electronic devices – that communicate over various networking interfaces ● and eventually can be connected to the wider Internet. ● Addresses many domains: – Health, Agriculture, Transport, Cities, Industry ● Critical in many cases: Need to Secure & Privacy Proof
  5. 5. 5 https://social.samsunginter.net/@rzrSamsung Open Source Group 2018 Privacy is about Trust and Control ● Ownership of personal data – Shared, Transferred, Revoked, Logged, Retrieved and DELETED ● depend on time and context ● Services operators should comply regulations: – EU: General Data Protection Regulation (GDPR 2018) ● Risk to privacy in the IoT is HIGH!!! ● “Privacy by design” opportunities – Prevent data collection in first place→Keep data local if possible ● Limit usage of cloud, apps or “captive models” – New security challenges (Decentralize, reduce surface of attacks)
  6. 6. 6 https://social.samsunginter.net/@rzrSamsung Open Source Group 2018 Motivations for Open Web Of Things ● Open web platform promises: – Security (isolation in browser) – Enhanced privacy (DNT) ● Security is not same as Privacy ! ● Think decentralized ! – may be harder to secure ● But more resilient – Edge: Computation on nodes ● Web of Things (WoT) – An application layer for IoT – with interoperability – Specification work by W3C – And FLOSS implementations
  7. 7. 7 https://social.samsunginter.net/@rzrSamsung Open Source Group 2018 Project Things by
  8. 8. 8 https://social.samsunginter.net/@rzrSamsung Open Source Group 2018 Mozilla’s IoT Project Things Overview ● Framework of software/services – for connecting "things" to the web ● Things Model: Semantic to describe properties ● WebThings: provide Http(s) REST API ● Gateway to connect WebThings – Rule engine and nice Web UI (PWA) ● Cloud: Remote access facilities
  9. 9. 9 https://social.samsunginter.net/@rzrSamsung Open Source Group 2018 W3C WebThing model & Thing Description ● Models complies to W3C schemas served on HTTP – using Javascript, C/C++, Rust, Python, uPython etc… ● Actuator example: RGB Lamp (webthing-ardiuno/example) curl http://esp8266.local [{"name":"Dimmable Color Light", "type":"dimmableColorLight", "href":"/things/dimmable-color-light", "properties":{"on":{"type":"boolean", "href": "/things/dimmable-color-light/properties/on"}, "level":{"type":"number", "href": "/things/dimmable-color-light/properties/level"}, "color":{"type":"string", "href": "/things/dimmable-color-light/properties/color"}} }] Names = endpoints
  10. 10. 10 https://social.samsunginter.net/@rzrSamsung Open Source Group 2018 Mozilla IoT gateway ● Purpose: – Connect all webthings in a LOCAL network – Provides GUI: Progressive web app ● to monitor and control things – Create Users and Access control using JWT – Optional remote control using mozilla’s proxy ● GNU/Linux Support: – Download Reference RaspberryPi image (2, 3) – Port to ARTIK5 or ARTIK7 (ARMv7) use node-10 or docker container – https://github.com/rzr/webthing-iotjs/wiki/Gateway
  11. 11. 11 https://social.samsunginter.net/@rzrSamsung Open Source Group 2018 Sharing flow between owner and user ● Owner setup gateway (connect lamp): – create and allow user(s) to control thing ● User login to GW using OAuth (JWT issued) gateway="https://sosg.mozilla-iot.org" or "gateway.local" thing="things/http---esp8266.local-things-dimmable-color-lamp" property="properties/color" curl "$gateway/$thing/$property" -H "$auth" -H 'Accept: application/json' {"color":"#ffff6f"} ← Or use alternative app: webthings-webapp: Tizen or Android/SamsungInternet (PWA)
  12. 12. 12 https://social.samsunginter.net/@rzrSamsung Open Source Group 2018 Gateway is extensible using add-ons ● Support other protocols: ZigBee... ● Start with virtual things adapter – Usage: “Burger menu” / Settings / Addons / “Virtual Things” Add ● Contrib: Generic sensors – Abstractions of I2C drivers/modules: ● Temperature, AmbientLight … – plugged on gateway’s device ● Today we’ll use “Thing URL” Adapter – to connect webthings using HTTP URL
  13. 13. 13 https://social.samsunginter.net/@rzrSamsung Open Source Group 2018 Every project has challenges, and every project has its rewards. ~Stephen Schwartz
  14. 14. 14 https://social.samsunginter.net/@rzrSamsung Open Source Group 2018 IoT Problems and Solutions ● Constrained IoT devices: – Cloud connected ● Privacy issues – Easy to prototype: ● Arduino – Harder to deploy at scale ● Limited on resources ● Native development – on many RTOS ● Few experts developers ● Technical strategies: – Edge computing ● Data stay on nodes or in LAN – Abstraction with high level API ● Port runtimes not apps code – Portability and standards ● Script languages for MCU – JavaScript, Python, LUA… ● Target existing developers base
  15. 15. 15 https://social.samsunginter.net/@rzrSamsung Open Source Group 2018 JavaScript: Language of the Web for IoT ? ● JavaScript is everywhere! – Many web developers → Many application developers – Easy leaning curve, Faster and Lower cost of development: ● Standardized and established communities: – is the leading JavaScript runtime (based on V8 engine) – NPM repo over 500K modules ● JS Interpreter can fit even into constrained devices – Few embedded devs to focus more on platforms than apps – Can run on even low end devices using JerryScript ● (RAM:64K+ROM:200K) Integrated in IoT.js, Zephyr.js, Tizen:RT "Any application that can be written in JavaScript, will eventually be written in JavaScript" ~Jeff Atwood
  16. 16. 16 https://social.samsunginter.net/@rzrSamsung Open Source Group 2018 Tizen:RT extends Tizen ecosystem ● Tizen – Is based on Linux Kernel – Shipped into ● High end consumer electronics – Mobile, TV, Wearables etc – Open to developers ● Native, C/C++ (EFL) ● HTML5 ● DotNet ● TizenRT – Is based on NuttX Kernel ● for constrained devices: – Ie: Cortex M3 (RAM=30KB Flash=512KB) – For low end IoT devices: ● Open APIs (C, JavaScript) ● Connectivity ● Reliability ● Security – Support: ● Qemu, ARTIK05x
  17. 17. 17 https://social.samsunginter.net/@rzrSamsung Open Source Group 2018 WebThing-IoT.js to power WebThings on IoT.js ● IoT.js runtime is powered by JerryScript – Features: GPIO, I2C, https and more – Prototype on GNU/Linux Debian derived OS – Deploy to constrained device: 05x on RT ● Webthing-iotjs is a fork of webthing-node for IoT.js – Continuously rebasing to align – Limitations: ES5.1, and some parts removed: ● mDNS, Websockets (actions, events)… – https://github.com/rzr/webthing-iotjs/wiki
  18. 18. 18 https://social.samsunginter.net/@rzrSamsung Open Source Group 2018 050X board as WebThing ● Running: – TizenRT – IoT.js – Webthing-iotjs ● Actuators – LEDs (GPIO) ● Sensors – Button (GPIO) – Analog (ADC)
