Abstract
- ABSTRACT Most of broadcast encryption schemes do not provide source authentication property. This allows an adversary to launch impersonating attacks. Therefore, broadcast encryption scheme without source authentication is not applicable in our real life as it is. In this paper, we propose two source-authenticated broadcast encryption schemes that achieve both confidentiality and authenticity simultaneously. Ciphertexts in both schemes are of constant size, independent of the size of the receiver set. The first scheme is particularly efficient in case of pre-computation, whereas the overall performance of the second scheme is better than that of Selvi et al.'s scheme.
