Sorry for an extremely nooby question, but your comment makes me wonder:
Are Snapdragon and Exynos architectures that alike? I mean, do you have any preliminary idea how easy it would be to apply your Snapdragon method to an Exynos SoC?

However, Exynos uses a TrustZone TEE implementation to implement the KeyMaster module, just like Qualcomm's Snapdragon. This means that unless that TEE implementation uses a hardware key which is not software accessible, the same issue would be present. Of course, reverse-engineering a new TEE implementation would take a long time... But it sounds like it could be fun.
You should be aware that people like you are unsung heroes and I'd like you to know that many of us who are busy struggling to stay afloat are feeling better knowing that people like you are doing the work you do.
Have that in mind. I wish you well.
