[1] [2] SGX is designed to be useful for implementing secure remote computation, secure web browsing, and digital rights management (DRM). [3] Other applications include concealment of proprietary algorithms and of encryption keys. [4] SGX involves encryption by the CPU of a portion of memory (the enclave).
Firefox's implementation of EME uses an open-source sandbox to load the proprietary DRM modules, which are treated as plug-ins that are loaded when EME-encrypted content is requested. The sandbox was also designed to frustrate the ability for services and the DRM to uniquely track and identify devices.
FairPlay-protected files are regular MP4 container files with an encrypted AAC audio layer. The layer is encrypted using the AES algorithm. The master key required to decrypt the audio layer is also stored in encrypted form in the MP4 container file. The key required to decrypt the master key is called the "user key".
