摘要
TLCH协议是一个适用于安全组播通信且可扩展性较好的组播密钥管理协议。它基于LKH的思想,采用双层的控制者的层次结构,并使用单向函数进行密钥更新,达到了较低的计算开销。使用hash函数对TLCH组播密钥管理方案中成员加入时的密钥更新算法进行改进。与原来的TLCH相比,改进后的TLCH可以进一步降低了通信开销。
TLCH protocol is used in secure multicast communication, and it is a very scalable multicast key management protocol. It is based on the idea of LKH. TLCH relies on two levels of managers, and use one - way function to rekeying. So it achieved a lower computation overhead. In the present paper, we will use hash function to improve the rekeying algorithrn of multicast key management scheme TLCH. Comparing with original TLCH, the improvement of TLCH can reduce communication overhead more.
