Abstract
A method and system for transmitting content from a content provider to a caching server and then from the caching server to a viewer. The method comprises encrypting the content with a pre-encryptor application before the content is transmitted to the caching server. The pre-encryptor application uses a pre-encryption subkey provided by a key storage service to perform the pre-encryption. The key storage service is a stand-alone component of the system and generates, stores, and distributes the pre-encryption subkeys.
