A KEY AGREEMENT FOR LARGE GROUP USING BILINEAR MAPSKey Agreement Scheme • March 21st, 2013
A key agreement scheme for large dynamic multicast group systems has been designed to cope with such applications including pay-tv, teleconferencing, collaborative work, online games, and so forth. To avoid heavy loads and unauthorized accesses to the system, it is necessary to construct an efficient and secure scheme. Some recently released schemes have tree-based underlying structures. The efficiency of these tree-based schemes is closely associated with the height of the underlying tree. In this paper, we propose a secure and efficient key agreement scheme for large groups that adopts a quad tree as the underlying key tree.
