Protecting Flash Lite content packaged in a Symbian installer with OMA DRM 1.0 Forward Lock

As a mobile architect, I've spent some time researching the solutions to deliver Flash Lite content protected with digital rights management (DRM). Recently I authored a Developer Center article titled How to protect Flash Lite content with OMA DRM 1.0. To follow up on that research to protect Flash Lite media, I went a step further and found a way to protect Flash Lite content that is packaged using a Symbian installer, which uses the .sis file format.

A Symbian installer for Flash Lite content offers two major functionalities:

  • A launcher (Symbian C++ application) which launches Flash Lite content
  • A menu icon that allows the user to easily launch the Flash Lite content

To learn more about working with OMA DRM 1.0, please refer to the article referenced above.

You can use the method described here to protect Flash Lite content packaged into .sis format (also known as a SIS installer) on the following platforms:

  • Nokia S60
  • Samsung (based on S60 technology)

In this article, I'll provide information on how to package your Flash Lite mobile content into a Symbian installer, which is the first important step. I'll also cover how to create a Protected Installation Package (PIP) and describe the process for applying and testing the PIP package. For the purposes of this article, we'll be using the Nokia Mobile Internet Toolkit.
