Improved R-LKH Algorithm
Yaping Deng · Jisuanji gongcheng · 2008
Because some disadvantage of the R-LKH scheme which is one algorithm of the multicast rekeying, such as the inefficient rekeying andhigh computing spending of group controller and member, this paper proposes an improved R-LKH algorithm which increases the rekeyingefficiency and reduces the group traffic by adopting the efficient rekeying algorithm which combinies one-way function and random number.Itanalyses and compares the traffic of multicast and unicast when the members join or leave the group.The results show that the improved algorithmneeds less traffic and computing spending than the R-LKH.
