Scalable P2PSIP conference key management scheme
可扩展的P2PSIP会议密钥管理协议

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.
