Abstract: In wireless networks high-valued transmissions would need to be encrypted and only paying users should have the decryption keys. As a result, it is very important to securely distribute the multicast data encryption key to a set of legitimate subscribers. Secure key distribution is one of the significant challenges in secure multicast over wireless networks. In this study, we analyze number of key distribution schemes that offer a novel solutions for securely distributing the group key and re-key messages for joining and leaving a mobile host in secure multicast group. We focus on 3 different approaches of group key management The Modified Huffman Technique, Key Management Using One-Way Function Trees and Kronos. We perform a comparative study on these three techniques. We also study the issues related to multicast key management and propose some solutions to overcome those difficulties.
