A comment on EME, CDM, AES, CENC, and Keys – Building Blocks of DRM. Parent comment
- How does the program making use of it make sure it's not been patched so the code that's supposed to run in the enclave runs without one?
- How does it know it's not being run on an emulated CPU or in a VM? And that those checks haven't been patched out, too?
- How does it make sure the OS is cooperating? I assume there is some cooperation required from the kernel at least.
