Abstract: In this paper, we present an authentication scheme for group-based peer-to-peer 3D streaming that takes advantage of secure group communication to reduce computation overheads of authentication. Users of the same interest first form a group, and one of the users is then elected to be the trusted leader, who is to download 3D contents, to verify their authenticity and integrity, and to send group members a checksum value for each 3D content piece via group secure channels. By the encrypted checksum values, a group member can authenticate 3D contents downloaded from any source. Since checksum is cheap to compute, much computation is saved. We have evaluated the computation saving of the proposed scheme for the case of progressive meshes based on the hash chain signature 3D streaming authentication scheme. We have also evaluated the rendering quality when embedding hash chain signatures into the least significant bits (LSBs) of the mesh data to make the signatures imperceptible. © 2009 IEEE.
