摘要
为了减少在密钥生成时的数据通信,在分析Park密钥预分配方案的基础上,提出一个基于传感器ID的密钥管理方案。该方案不仅明显降低了生成密钥时的通信开销,而且确保所有的节点均能建立安全链路。分析表明,该方案还具有较强的抵抗攻击能力。
In order to reduce the communication cost in the sensor networks key establishment, proposed a key distribution scheme based on the node ID on the basis of analysis of the Park' s pre-distribution mechanism. It not only reduced the communication cost, but also ensured that all nodes can establish secure links. The analysis indicates that the proposed scheme substantially enhanced the ability against attacks.
