| Abstract: | Based on discussing the security demand of WSN, and analyzing the challenges to the key management scheme in the WSN and describing the metrics of it, it introduced two kinds of key management models for WSN. One based on the key distribution center （KDC） and the other based on key pre-distribution. By analyzing and comparing the previously-proposed random key pre- distribution schemes in terms of the connectivity, resilience against node capture and the max network size, it indicate their merits, weaknesses and the suitable scenarios. |
