| Summary: | 碩士 === 國立雲林科技大學 === 資訊管理系碩士班 === 97 === P2P transmission technology is very popular at present, because it can allow two users to share files directly rather than through a third party. For the users, means users can receive the latest information from the owners, and don''t have to wait for digital content uploaded to the server. For the providers, means providers don''t have to waste the extra time and cost to manage the servers. In addition, a lot of factors accelerate the practicability of P2P network, include the increased availability of bandwidth, computing capacity raise, storage capacity expansion and network information is increased. However, P2P transmission technology is also a notorious breeding ground for illegal activities, it makes piracy and illegal use easier, and many users use it in violation of copyright law to engage in the exchange of information.
In order to solve the bad impression of the P2P transmission structure, implement Digital Rights Management (DRM) for P2P network is feasible. This study improved distributed DRM architecture, and implement the novel key management scheme, in the existing P2P live streaming. Live streaming have the characteristic that is downloaded immediately, watched immediately and deleted immediately, to prevent digital content to be reused. Implement the novel key management scheme, makes a warning only when the user there is no decryption key, and the rest of the time, users will not feel the DRM mechanisms of control, so users can upgrade the mechanism for the acceptance.
