【 摘 要 】

We consider broadcast encryption schemes wherein a center needs to broadcast a secret message to a privileged set of receivers. We prescribe a probability distribution P on the privileged set. In this setting, the transmission overhead can be viewed as a random variable over P and we define its expected value as the average transmission overhead (or ATO).
