In this paper, a new public-key broadcast encryption scheme, which is asymmetric and without involvement of trusted third parties, is proposed by using the "subset-cover" framework and the identity-based encryption scheme of Boneh and Franklin. This scheme is the first concrete construction of an asymmetric identity-based public-key broadcast encryption that does not rely on trusted agents and the costly Oblivious Polynomial Evaluation mechanism. Moreover, this novel work contains other desirable features, such as efficient encryption and decryption, low memory requirements, traitor tracing, asymmetry and non-repudiation. The tracing algorithm of this system is more efficient than that of the previous ones. © Springer-Verlag Berlin Heidelberg 2005.
