碩士 === 國立中正大學 === 通訊工程研究所 === 101 === The P2P-SIP multimedia conferencing concept is to let users to share conference resources through a network to improve the the problems that traditional model of centralized architectures meeting, such as high loading at centralized component, single point of failure and expensive infrastructure costs. By using the p2p model, the service industry can achieve the benefits of decentralization effectively. But, owing to the service component is not provided by the industry as traditional centralized architecture, so the data transmission security and privacy will not as good as before. By these reasons, this paper proposes a key management scheme based on P2PSIP multimedia conferencing communication. The main purpose is, we hope to design a key management scheme upon the established application multicast tree. Without changing the structure of the P2P environment, it is still has some privacy and communications security. When user uses Internet communication services, it should not only change the public and private key encryption information period, but also based on the forward and backward security issues. In other words, the meeting will process the communication encryption key during the conference period, according to the user join and leave behavior. In addition, we also hope that through reduced the overall time of rekeying to further improve system performance and reduce the possibility of the important data disclosed.
