摘要： The present invention provides a method of distributing content to a plurality of clients. The method on a server begins with accessing content to be distributed to a plurality of clients and identifying a first type of content to be distributed as crucial content and identifying a second type of content to be distributed as non-crucial content. The crucial content is any content required to properly render, after a decryption process, the content. The non-crucial content is all the other content to be distributed. The crucial content is encrypted with a first encrypting key which is unique to each of the plurality of clients. The crucial content which has been encrypted is transmitted. The non-crucial content is transmitted to the plurality of clients.
