SU Jin-hai · Jisuanji gongcheng · 2010
The ideas of group re-keying algorithms based on secret sharing using the LKH tree are proposed in this paper.The algorithms construct a message using secret sharing with the dynamic change of group members.The group members can reconstruct the new group key.It is proved that the new algorithms have obvious superiority than that of the previously proposed algorithms on communication and computation,and are suitable for large dynamic group.
