摘要 密钥更新是DTMSN中的数据传输安全的保证,现有DTMSN中的密钥更新模型都是基于节点接触率相等的假设上提出的.本文针对实际DTMSN中节点接触率不相等的问题,通过对基于转发节点的密钥更新模型的研究,提出了一种适用于不等接触率的DTMSN的密钥更新模型,并通过仿真程序对模型进行了验证. The key updating ensures the safety of data transmission in Delay Tolerant Mobile Sensor Net works. Existing key updating models in DTMSN are based on the assumption that node contact rates are equal. By analyzing the characteristics of the key updating module based on forwarding nodes, this paper proposes a key updating model in DTMSN with variable contact rate and validates it by simulation.
