“…It got the network performance and happened network overhead too much because of the security resource to provide safe and efficient multicast services and the structure in this model. He also explained his other idea in [Hoon Ko, 2006]. It showed that the distributed/hierarchical scheme minimize the overhead and reduce the number of key and key updating operation than other multicast schemes.…”

Many users who are in a cyber-space usually want to join the social group to have or to share their information. Now, there are two ways to join the group, the group manager invites them, and the users who want to join ask the owner. These days the group polices usually follow this way. But, it can be faced a security problem when the manager send group messages in near future because they don't have any securities. Therefore, the security modules to join groups will be needed when they join the group or when they read the group messages. To set the security, we have to think how to keep the key such as a generation /an update/an arrangement, because all users need the key to join the groups or to read the group messages by decrypting. The key are going to be used to joining the group when it dynamically changes such as frequent group joining and leaving. If it applies or uses the existing methods in the smart cities which consider the users who will move globally, it could easily assume that the overhead/the cost of CPU will be increased and it follows capacity down because of lots of the key updates. So, to let them down, we suggest three key strategies, a group key, a subgroup key and a session key in this paper.

“…A common design for key management protocol is to support the security of network, transport and application layer [4]. When a change in group membership occurs, the new key needs to be generated and then sent to all members of the group [5]. It means one user/member can affect all members to be updated, which is referred to 1-affect-n problem.…”

Key management is one of the challenging issues in group communications. It is generally used to secure multicast data transmission as well as preventing potential eavesdropping by malicious attackers. Group security key should be maintained for data encryption, while group key update and dissemination processes are required when a new user joins or leaves the group, which eventually lead to high communication cost. Since eavesdrop activities can be initiated by capturing the disseminated keys, higher communication cost due to frequent updates may also increase the possibility of attack of multicast transmission. In this paper, a key management scheme for IPv6 networks is proposed to reduce communication cost and therefore, fewer security risks. The obtained results from test-bed implementation show the efficiency of proposed method in terms of communication cost, number of updated paths and security index due to key updating, while at the same time achieving both forward and backward secrecy.
