We present a novel scheme of broadcast encryption that is suitable for broadcast servers such as pay TV services. The important feature of our scheme is that the length of a broadcast string in our scheme is independent of the number of receivers in the system; hence it is suitable for large groups. Our scheme is based on a trapdoor encryption technique under the RSA assumption. We also describe a variant of our scheme which provides stronger security.
