Easy, the check that requires it to be sent to a compliant display is dependent on the decrypt functionality (or the other way around).
This is only hard if you try to make it hard.
- MereInterest 5y agoIt's only hard if an adversarial relationship is making it hard, which is exactly the case for DRM implementations. If you're writing code that runs in a trusted environment, then it is as simple as enabling decryption conditional on checking the display. That's only appears because trusted environments are nice simple places where code, file checks, system calls, CPU instructions, and all the other niceties work as intended.
