Design and Implementation of the IMS-IPMP System in Convergence Home-Network Environment

摘要

In this paper, we have designed and implemented the IMS-IPMP system suitable for CHE. We have complemented weakness of the inflexible contents distribution among fixed subjects of the existing system. To take into account the environment where a single user can be flexibly changed in CHE, it supports interactive contents transaction within an identical domain. Furthermore, it supports contents super-distribution among multi-domains that a CC well known the market characteristic of the specific domain, can be easily changed and transact contents for the 2nd distribution. Moreover, it supports license format which can be flexibly used in multimedia devices under the wire/wireless environment. Finally, the proposed system support security including device spoofing attack prevention, illegal license alteration attack prevention, illegal user's attack against contents prevention, and so on.
