title = "A collusion resilient key management scheme for multi-dimensional scalable media access control",
abstract = "This paper proposes a novel key management scheme for multi-dimensional scalable multimedia access control. We build up a collusion-attack model and prove that the proposed scheme is indeed resilient to collusion attack. The lower bound of number of the segment keys is also given in the analysis. We consider the key management problem on partially order set and propose a general approach consists of a poset decomposition step and an element projection step. Under the proposed framework, a novel hierarchical 3D poset decomposition approach is further developed. The proposed scheme is the first provable collusion resilient scheme in 3-dimension (and higher) scenario. It can be easily adapted to other scalable dependence structure and higher dimension. Analysis on the proposed scheme proves its collusion-resilient property.",
