  • Systems and methods for broadcast encryption optimization and scalability
    Patent number: 8483390
    Abstract: A content distribution method with broadcast encryption, comprising: executing a setup process, comprising: generating public domain parameters, generating a server secret, and generating one or more client private keys, one for each content receiving client; executing an encryption process, comprising: generating a cipher text using the server secret, a subscriber set, and a randomness, the cipher text being constant and independent of total number of content receiving clients in a distribution network, generating a plain text using the server secret and the randomness, encrypting an original content into an encrypted content using the plain text; distributing the client private keys to the content receiving clients; distributing the cipher text to the content receiving clients; broadcasting the encrypted content through the distribution network; and executing a decryption process on the encrypted content by each of the content receiving clients in the distribution network.
