This paper proposed a new hierarchical group key management scheme for large Ad hoc network.In the scheme,divided group based on geographical location into several sub-groups,that reduced communication overhead for limiting message transmission distance within a sub-group.It adopted the combination of key agreement and distribution to generate,distribute and update group key,that made it avoid single point of failure while improving efficiency.Based security of the scheme on solving elliptic curve discrete logarithm problem.Through analysis,the scheme provides higher availability.
