The development of wireless communications provides mobility and accessibility to the wire communication users. Wireless sensor network is one of the leading wireless communication techniques. The security mechanism for wired network communication cannot be applied to wireless sensor network because of the limited resource and computing capability of nodes. Furthermore, communication errors frequently occur and the speed is low. Thus, efficient key management scheme is required in low-speed environment. In this paper, we proposed an efficient and secured master key-based scheme compared to the existing scheme. The advantage of our scheme is that establishing and renewing the pair-wise key is possible. In addition, it provides functions such as establishing group keys and renewing it. Furthermore, adding nodes is enabled through our scheme. The master key-based scheme can be applied to military operations and to radio communications for confidential communications. |
