Abstract  Abstract

The present invention relates to a method and apparatus for secure transmission. Each user is provided with a registration key. The long-time updated broadcast key is encrypted using the registration key and periodically provided to the user. The short-time updated key is encrypted using the broadcast key. Short-time keys are available for each broadcast message, where sufficient information to compute the short-time key is provided in the Internet Protocol header prior to the broadcast content. The broadcast message is then encrypted using the short-time key, where the user decrypts the broadcast message using the short-time key.
