Abstract

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 algorithm of multicast key management scheme TLCH. Comparing with original TLCH, the improvement of TLCH can reduce communication overhead more.
