| Abstract: | Source Authentication is one of the most important issues in information security. When authenticating real time streams, people are always concerned with the efficiency and pace of authentication. By using the hash function technology and the digital signature technology, this an authentication protocol for real time streams is designed and analyzed. This protocol has improved the efficiency of online phase and is applicable to the authentication of the real time streams in an insecure network. |
