Abstract: An apparatus is configured to protect the privacy of shared objects by loading shared object into a user memory of a rich execution environment. The shared object has an encrypted segment and metadata. A request for decryption is sent to a trusted execution environment and the encrypted segment is decrypted based on the metadata and a predetermined platform key to produce a decrypted segment.
