===== Lessons learnt from Tizen 3 security model =====

One of the major topic of an open system is the ability to install new applications. The applications installed must:

  * do what they claim, not more
  * respect the privacy of the users

To achieve that goal, Tizen 3 implements a model based on authorisations named "privilege" and on package  signatures made by distributors.

This document also contains in appendices a short description of the model of security of Tizen 3.
