2 Intro Tizen Linux kernel based Embedded OS for wide range of devices, where Mobile, Wearable, TV are maintained as device profiles with managed APIs for the backward compatibility of applications Tizen IoT New direction of Tizen to support IoT Devices, where the features of IoT devices cannot be limited with a fixed set of APIs 2 Welcome to visit us at the exhibition booth, Tizen IoT Bringup & Remote Firmware Update Tizen IoT Platform UX : Macaron

3 3 From Tizen 4.0 WHAT IS TIZEN IOT?

4 Embedded OS for IoT Devices Tizen IoT is a linux kernel based Embedded OS for IoT Devices, where the form factors of IoT Devices are not limited with a fixed set of APIs like Mobile, Wearable or TV Profile. Tizen 3.0 or before Tizen 4.0 or after Headless Device Type 4 No Headless Device Type Could not create new device via PDK Only Mobile/Wearable/TV Profile maintained - Profile is not maintained. - Any headless device can be created via PDK. Headed Device Type - TV/Mobile/Wearable Profile are maintained. - Any headed device can be created via PDK.

5 Device Ecosystem for IoT Building blocks qualified in legacy profiles will be reused for creating new IoT devices. A small number of IoT device presets will be given in PDK/TIC (Tizen Image Creator). Any IoT device will be created with TIC and contributed as a new IoT device preset. Open Source Contribution Building Blocks IoT Device Presets Open Device Contribution Sensor Location Voice Web/Widget FW MM UI FW Headed Presets 5 Multimedia Network Input System Network Window Tizen IoT Core System Window UI FW Tizen IoT Core Lightweight App FW Lightweight App Security IoT.js FW System Network Sensor Tizen IoT Core Headless Presets Peripheral IO Wifi/IoTivity Open Hardware (RPi3, Artik5, Artik7)

10 Peripheral IO FW All device drivers of various peripherals cannot be included in Embedded OS for IoT Devices. Low-level Peripheral Interfaces for IoT Apps Native Application & User Space JS Application &. Drivers GPIO, UART, SPI, PWM, I2C will be supported. User Space Drivers IoT.js/JerryScript The access control and resource management for each peripheral b/w IoT applications should be provided with Service Daemon. Peripheral-io API Service Daemon (periperal-bus) 10 IoT Board kernel GPIO UART SPI PWM I 2 C Sensor Actuator LED 7-segment display GPS Images from samsung.com

11 Extensible Sensor FW More flexible way to add new application-level sensors with legacy sensor APIs The former way is to implement kernel drivers and sensor HAL, but not suitable to support the variety of IoT devices. Native API for creating application-level sensors in Sensor Provider App It allows sensor provider apps to define/publish new sensors for sensor listener apps. No limit on the sensor data sources. E.g. Peripheral IO, Platform Sensor Sensor Lister App Sensor Provider App Listen Create Publish 11 Platform Platform Sensor Sensor Sensor Framework Application Sensor Sensor Sensor Sensor HAL Sensor Plugins Sensor Sensor Data Sources Peripheral IO OCF Kernel Drivers Images from samsung.com

12 12 What do we provide for Tizen IoT? 3. IOT APP MODEL

13 Supported App Types Characteristics of IoT App App developers want to develop a simple IoT App quickly and easily. e.g. sensing and collecting data from the device, communicating with IoT cloud IoT App Model may not need legacy UI framework. e.g. APIs for controlling simple LED might be supported IoT App Types Headless (with Lightweight App FW) C Native App JS Native App based on IoT.js runtime Headed (with Legacy App FW) C Native App C# Native App based on.net runtime Applications Core JS Native Applications IoT.js Native API C-Native Applications C-Native API Web FW App FW UI FW Messaging Location Context Multimedia Graphics & Window Telephony Network & Connectivity System FW Sensor C#-Native Applications C#-Native API Security.Net FW 13 Base Library Linux Kernel & Drivers

14 Lightweight App FW Package Manager to Deploy Apps Install/Uninstall/Update App packages with legacy Tizen Packaging format (tpk) Apps can be preloaded, downloaded and installed/updated/uninstalled in runtime Application Launcher to Manage the Process Life Cycle of Apps Manage App processes : Launch, Terminate, Recover App processes Each App is launched as a separated process with its protected memory Some Apps can be launched when system boots and keep running state while the system is on Some Apps can be launched on demand by some commands App launch request app A 1. App package install/uninstall/update request Package Manager Application Launcher app B 2. Manages App package db 5. App process is forked by the launcher app package database 3. Load App info from db

15 IoT App Security App Sandboxing Each app has its own Smack(Simplified Mandatory Access Control Kernel) label. Each app can not send IPC and signal, read/write other app files. Access Control Important system objects are Smack labeled System daemons will make use of Smack and enforce access control The privileged accessibility (ex. Privacy related access) by apps is controlled by Cynara (Policy Checker Service) App Signing To ensure app integrity and identify a developer and distributor Key Manager Secure Repository for keys, certificates, and sensitive data 15
