Key Management Scheme Applicable to Various Topologies of Sensor Networks

A sensor node has extremely limited power supply capacity and operation performance, therefore, key management schemes that can be achieved with less calculation in sensor networks have been proposed. However, these key management schemes cannot be flexibly applied to various connection topologies and network configurations. In this paper, we propose a key management scheme that can be generally used in a network that supports various connection topologies and that is capable of adding new nodes. Finally, we implement and evaluate our scheme.
