Abstract(in English) Download of multimedia contents is an attractive communication service for high speed networks such as the ADSL.Under such au environment, digital streaming protocols are often used.The difficulty to authenticate the digital streaming data is as follows.First, the overhead of signing and verification processes causes a delay of transmission.Second, authentication must be possible even if some packets in the sequence are missing.To solve the above issues, we propose a practical authentication mechanism for digital streaming service.Our mechanism is based on hash chains of authenticating packets, which contains two layered chaining hierarchies.We also study a comparison with the other mehtods to show that our mechanism is practical and efficient.
