摘要:
Technologies for secure content packaging include a source computing device that transmits a secure package to a destination computing device. The destination computing device establishes a content policy trusted execution environment and a key policy trusted execution environment. The content policy trusted execution environment may be established in a secure enclave using processor support. The key policy trusted execution environment may be established using a security engine. The key policy trusted execution environment evaluates a key access policy and decrypts a content key using a master wrapping key. The content policy trusted execution environment evaluates a content access policy and decrypts the content using the decrypted content key. Similarly, the source computing device authors the secure package using a content policy trusted execution environment and a key policy trusted execution environment. The master wrapping key may be provisioned to the computing devices during manufacture. Other embodiments are described and claimed.
