摘要：
The present invention discloses an apparatus and method for securely generating a content decryption key in an endpoint device. In one example, a nonce is acquired from a packet header from a message received at the endpoint device. The content decryption key is derived utilizing a one-way content function that uses a channel key and the nonce as input parameters.
