摘要
传感器网络中有必要使用加密技术对节点间的通信进行保护。基于传感器ID的密钥管理方案采用二元多项式,实现了包括密钥分配,密钥更新和对传感器被破坏的检测等功能,被破坏的密钥能够自动恢复,同时减少了对内存和计算能力的要求,更能适应传感网络的环境。
WSNs require cryptographic protection of communications between sensor nodes. Adopting bivariate polynomials, ID-Based key management scheme has these functions including key distribution, key updating and sensor capture detection. Compromised nodes can recover automatically. Meanwhile, with lowered demands on memory and computational ability, this scheme is more suitable for sensor networks.
