Dreamstation 2 Encryption Idea

Post by jdm2857 » Tue Oct 26, 2021 8:30 pm

I don't know if this is practical, but instead of trying to decrypt the DS2 data (which could be virtually impossible), might it be possible to flash the machine with revised firmware that omits the encryption step?

Just a thought.

As demonstrated by the AirBreak project on ResMeds, flashing a modified firmware *might* be a possibility.

The practicality is still prohibitive:
  • The AirBreak project is dying on the vine, I'm guessing a similar project to bypass encryption would have a similar fate
  • The skill level required is significant
  • The market share for DS2 is tiny compared to Air10s, this reduces eligible devices, people available for the task.
  • Assuming it was possible, the market share of modded devices would be so low, I doubt the OSCAR team would be interested in spending the resources to support it.

Just interested, what is the market share of Phillips DS1 to Resmed AirSense 10 ?????

You can put gold paint on a turd, but it is still a turd.
