摘要:
Techniques for securing content in an untrusted environment are provided. Content is encrypted and stored with a content delivery service in an encrypted format. Encrypted versions of a content encryption/decryption key and a first key are also housed and distributed by the content delivery service. The first key is used to decrypt the encrypted version of the content encryption/decryption key. The content delivery service is unaware of the content encryption/decryption key and the first key; and the content held by the content delivery service is encrypted with the content encryption/decryption key. Principals securely share, create, manage, and retrieve the encrypted versions of the content encryption/decryption key and the first key from the content delivery service using secure communications. The encrypted content is obtainable via insecure communications from the content delivery service.
