Secure and Reliable Centralized Multicast Key Management Scheme
Zhao Ze-mao · 2011
By constructing two special polynomials,a new multicast key management(MKM) scheme——Hash Function-based Multicast Key Management(HFMKM) scheme was proposed,which was based on hash function and two-variable one-way function.The properties of both centralized and distributed were combined in this scheme,so it overcame the defect of conventional centralized flat schemes,whose security totally depended on the Group Controller(GC).With Comparing and analyzing it with GKMP scheme,the results showed that the HFMKM scheme obviously improved the security and the overall performance.It is a new security MKM scheme.
