Abstract: A new family of broadcast encryption schemes (BESs), which will be called linear broadcast encryption schemes (LBESs), is presented in this paper by using linear algebraic techniques. This family generalizes most previous proposals and provide a general framework to the study of broadcast encryption schemes. We present a method to construct LBESs for a general specification structure in order to find schemes that fit in situations that have not been considered before.
