Abstract:
|
Communication via self-organization is a practical and most common model for wireless sensor network. Its security, efficiency and cost and corresponding key management are one of the key research topics on WSN security. This paper proposes a group key management scheme for WSN based on an original self-organized structure, grid-loop. The group which we called Grid-loop is constructed on distributed Minimum Spanning Tree. Our group key management scheme has many advantages over cluster-based scheme. The analysis and comparison demonstrates its feasibility, efficiency and security for key establishment and maintenance in Wireless Sensor Networks.
