Key pre-distribution scheme based on block design for wireless sensor networks
无线传感器网络中基于区组设计的密钥预分配方案

Key management is paramount for wireless sensor networks. A key distributing protocol based on block design and Blom's scheme was proposed. With the advantage of the block design, this scheme can substantially improve the network's connectivity. In contrast to other key pre-distribution schemes, this one has higher resilience to node compromise
