Multi-User
Tizen IVI Multi-user system 12
Tizen Multi-user requirement ● Guest log in by default ● Start Generic Application ● (e.g. rear cam, radio, ...) ● User logging in shall not stop running applications ● ID user is added on top of Guest. ● Multiple user can share the same Display ● (e.g. passenger and drivers) ● Users can exchange seats ● (and so Display) ● Security must protect the user data and the system data. 13
Dissociate Seat and User ● General Linux ● Before Login → No use ● Seat = Display ● IVI ● Before Login → Guest ● Login → add user to a seat ● User can change seat 14
What needs to change ● Application Frame work ● ● Login Manager ● ● Startup procedure ● ● Sécurity model To know more : join the session on Multiuser 15
Security
¿ Security in a Car ? 17
Tizen an integrated security ● Application isolation with controlled sharing ● No access to system privileges ● No undeclared data sharing ● No direct launch in session ● Per Application control over privileged resources ● Extensive control of system resources ● Fine grain control of the ressource ● HTML5 and Native Applications ● Multiple users on a device ● Application available for all or individual user ● No data contamination of uncontrolled sharing. 18
Three Domains Model A new simplified model for more efficiency in Tizen 3 ● "User" : user domain for user processes and data, ● "System" : system domain for system processes and their private data ● "_" : floor domain for static public data. ● Peers domains are used for ● System process change ID whenever possible ● Each User has a unique UID ● Each Application has a unique Smack label. 19
Per Application Manifest ● Manifest are fined grained e.g. Bluetooth ● bluetoothmanager ● bluetooth.spp (Serial Port Profile) ● bluetooth.opp (Object Push Profile) ● bluetooth.health (Health Device Profile) ● bluetooth.gap (Generic Access Profile) ● bluetooth.admin 20

Web Run Time
CrossWalk Architecture • Shared process model WebApp WebApp WebApp WebApp • BP is shared with all WebApps • Extension Extension Extension Extension WebApp contains EP and RP Process (EP) Process (EP) Process (EP) Process (EP) • RP is sandboxed and can’t do OS calls • Render Render Render Render RP delegates OS calls to BP via IPC Process (RP) Process (RP) Process (RP) Process (RP) • EP is not sandboxed and can do OS calls I I I I P P P P C C C C Browser Process (BP) Browser Process (BP) Tizen OS Tizen OS 23
CrossWalk Security • Policy is created during WebApp installation • API permission is checked against the policy during runtime • Policy contains <application context>, <privilege> tuple • Permission check has simple answer: ALLOW, DENY or ASK USER 24
Modello HTML5 UI ● HTML5 UI ● Proof of concept ● Reference ● Open Source Option ● Fully functional 25
Nice add-on
Tizen Goodies ● Graphic ● Build Systems ● Weston 1.5 with XDG and Layers ● OBS ● EFL 1.9 ● Yocto ● QT 5.3 ● Eclipse SDK ● Architecture ● Ozone ● IA 64 bits ● Gstreamer 1.2 ● IA 32 bits ● Automotive Middleware ● Automotive Message Broker ● ARM 32 bits ● Murphy resource management ● DLNA, WiFi P2P, DNLA, NFC, ... 27
