组播密钥的批次更新算法，基于LKH的单次密钥更新方案和Batch Rekeying方案的原理、结构和密钥更新过程等。并着重对 Batch Rekeying 方案的性能与单次密钥更新方案作了简单的比较。 通过比较和分析得到结论:定时更新的Batch Rekeying 方案在更新开销上比单次更新更有优势 -Multicast key batch update algorithm, Based on the LKH single Rekeying program and the program Batch Rekeying principle, Rekeying structure and processes. And Batch Rekeying focused on the performance of the program with a single Rekeying program with a simple comparison. By comparing and analyzing conclusions : regularly updated Batch Rekeying program in the updated overhead than a single update more advantages
