Abstract :
The key problem of securing multicast is to generate, distribute and update session encryption key (SEK). A group key distribution scheme utilizing a polynomial expansion with multiseed (M-PE) is proposed. Its operation is demonstrated by using multi-seed, the group member is partitioned to many subgroups. While updating the SEK, computation is needed only in one of subgroups, the other of them will use the computation history to update their SEK. Protection against unwanted access, computation complexity, communication costs and key storage of M-PE is discussed along with the comparison with some other existing schemes
