%X Key Distributed Center(KDC) is an important component for generating symmetric key in multicast communication without using public key cryptography.It is important to keep KDC security and provide efficient symmetric key service.Different from the current partition to domain or replication solution,the proposed scheme uses bivariate polynomials to construct threshold distributed pseudo-random function,distribute the bivariate polynomials across the KDC servers,only the united authorized set of servers can compute the pseudo random for key.It ensure certain number of unauthorized server will not threaten the security of the whole network after being attacked.Therefore,enhance the security of distributed KDC servers was enhanced,and bottlenecks or single points of failure can be prevented.
