| Abstract: | As muhicast communication is used extensively, its security muhicast key management becomes a problem. It is used for group members in one muhicast session to generate, refresh and transfer the keys for encryption and authentication. So the maintenance, scalability, reliability and robustness of keys should be carefully considered. This paper studies the existing problems in key management for multicast, and certain typical schemes. |
