Abstract

Secure group communication systems have become
increasingly important for many emerging network applications.
An efficient and robust group key management approach is indispensable

to a secure group communication system. Motivated
by the theory of hyper-sphere, this paper presents a new group
key management approach with a group controller GC. In our
new design, a hyper-sphere is constructed for a group and each
member in the group corresponds to a point on the hyper-sphere,
which is called the member’s private point. The GC computes the
central point of the hyper-sphere, intuitively, whose “distance”
from each member’s private point is identical. The central point
is published such that each member can compute a common
group key, using a function by taking each member’s private
point and the central point of the hyper-sphere as the input. This
approach is provably secure under the pseudo-random function
(PRF) assumption. Compared with other similar schemes, by
both theoretical analysis and experiments, our scheme (1) has
significantly reduced memory and computation load for each
group member; (2) can efficiently deal with massive membership
change with only two re-keying messages, i.e., the central point
of the hyper-sphere and a random number; and (3) is efficient
and very scalable for large-size groups.
