Identity-based secure group communications using pairings

In this paper, we discuss the construction and implementation of identity-based signature schemes that make use of bilinear pairing to get shorter signatures, and their application to authenticated group key agreement. Besides the introduction of two new signature schemes, the aim of this contribution would be to show that through such schemes one can get implementations for identity-based secure group communications that scale sufficiently well with respect to the number of involved parties. We run a set of experiments that corroborate our expectations.
