Providing authentication protocols for real time streams is a challenging task. This is because the authentication rate is very important for real time streams, whereas it is usually a bottleneck. Using improved online/offline signatures and hash chain techniques as tools, our proposed protocol greatly reduces the online computational and communicational cost and thus is more applicable to authenticate real time streams.
