Abstract :
In this paper, we propose a key management scheme in DRM which supports multi devices by using a secret sharing. The proposed scheme enables playing contents on registered devices only, and additional overheads are not occurring even if the number of registered devices are increased. We measured the overheads occurred by the proposed scheme through a prototype implementation, and showed that the scheme is applicable to consumer devices.
