WHAT IS TIZEN IOT?

From Tizen 4.0

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.

No Headless Device Type

Could not create new device via PDK

Only Mobile/Wearable/TV Profile maintained

Headless Device Type

- 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.

Tizen 3.0 or before Tizen 4.0 or after

□ All device drivers of various peripherals cannot

be included in Embedded OS for IoT Devices.

□ Low-level Peripheral Interfaces for IoT Apps

– GPIO, UART, SPI, PWM, I2C will be supported.

– The access control and resource management for

each peripheral b/w IoT applications should be

provided with Service Daemon.

11

Extensible Sensor FW

Images from samsung.com

□ 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.

3. IOT APP MODEL

What do we provide for Tizen IoT?

13 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

4. App launch request

5. App process is forked by the launcher

□ 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

15 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

16 16

IoT.js/JerryScript □ JerryScript

– Ultra Lightweight JavaScript Engine (Under 160KB Binary size on ARM32 Linux)

– Supports ES5.1 and a few selected ES2015 features (Promise, Typed Array and so on)

□ IoT.js : JavaScript Framework

– Easy to develop by trendy JavaScript programming methodology

– Easy to maintain & modify logic by updating script only

Easy Setup □ A sequence of set-up interactions between mobile users and IoT

devices where the IoT device is ready for users to use.

□ Once Easy-setup is done, IoT device can not only connect to

network, but also be registered to IoTivity cloud server

□ The Goal of Easy Setup is that Mobile provides an

information securely to IoT Device as follows:

– WiFi AP info. such as SSID, PWD, etc.

– Cloud Server info. such as Auth Code, IP Addr, etc.

– Initial device info. such as lang, country, etc.

① Out of box ② Transfer WiFi AP Information via Soft AP Network

OCF Cloud

Resource Directory

④ Transfer Cloud Access information via WiFi AP Network

⑤ Device Registration to IoTivity Cloud server

③ Connect to Home WiFi AP
