In case you are using RTMPe to protect your content, pRTMP is a new feature that is amazingly easy to upgrade to, and significantly increases your content protection. pRTMP is the equivalent to PHDS, secure content protection based on Adobe Access 3.0, but without requiring the actual license server.
Flash Media Server encrypts on-demand media files and embeds a Flash Access 3.0 license in the DRM metadata of the content. Flash Player and AIR clients communicate with Flash Media Server to play the media. Protected RTMP does not require a license server; the license is embedded in the content metadata and a client receives it along with the media.
Protected RTMP is more secure than RTMPE because it uses Flash Access 3.0 DRM content protection. Protected RTMP encrypts the content whereas RTMPE protects the communication channel. Because data is unencrypted, companies like comScore and Nielsen can measure protected RTMP video.
Because the content is encrypted, unauthorized replay is impossible. Protected RTMP content can be decrypted only by Flash Player and AIR clients that have the shared domain private key.
There is no way to use an RTMPE connection between servers and decrypt the content on Flash Media Server. Different applications that access common media files must have consistent setup with respect to Protected RTMP. That is, you should not access the same media file over both protected and unprotected RTMP.
Protected RTMP simplifies deployment and increases security because:
- Flash Media Server is the only server required.
- No license server is required.
- No domain server is required.
- All media can be packaged with the same common key.
- Content is encrypted with Flash Access 3.0 DRM protection.
Protected RTMP uses 128-bit AES encryption. RTMPE uses 128-bit RC4. [via Flash Media Server live docs]
If you have valuable content, and currently rely on RTMPe streaming, this is a must have security upgrade. More details on pRTMP in the Flash Media Server live docs.
