In order to meet the requirements of low latency and high scalability for P2PSIP conference,this paper proposed a hierarchical conference key management protocol-HOAKA.In HOAKA,conference nodes were divided into two classes according to their capabilities,a small amount of high-performance nodes managed the conference,and all the conferees agreed on a conference key by using one-way accumulator.The results show that HOAKA has not only high security,but also low computing and storage overhead as well as small key update delay.It has good scalability.
