dc.description.abstractThis paper proposes a novel broadcast encryption (BE) approach which combines the traditional one and time-bound cryptographic keys. The developed BE provides heavy reduced cumulative communication overhead and yields increased security. The reduction of the communication overhead is achieved via employment of time-bound session encrypting keys (TB-SEKs). The increased security against ciphertext only attack appears as a consequence of the reduced communication overhead and the increased security against the chosen-plaintext attack is obtained via employment of the time-bound key-encrypting keys (TB-KEKs). Appropriate methods for management of TB-SEKs and TB-KEKs are given. The proposed scheme is compared with traditional BE schemes and the advantages as well as the related trade-offs are pointed out.en_US
