摘　　要：证券业务数据具有较高的私密性需求,因此在个人移动终端密钥进行更新可以降低数据的泄露风险。目前密钥主要使用Internet接入、GPRS等公网进行分发。传统的密钥分发方式导致成本高、安全性较低的问题。因此文章依据行人移动距离基于幂截顶分布的规律,提出基于延迟容忍移动传感器网络技术的无线密钥分发方案。通过仿真实验验证终端覆盖率,结果显示基于洪泛方法的密钥分发方式,移动节点更新率在81小时后达到90%,并减少了密钥在公网中的传输机会。The securities business data has high confidentiality requirements, thus the update of personal terminal key can decrease the risk of data leakage. At present, the key uses Internet to access and GPRS network to distribute. Traditional key distribution mode leads to high cost and low security, therefore according to the rule that the pedestrian distance distribution is based on power cut top, this paper puts forward a wireless key distribution scheme based on delay tolerant mobile sensor network technology. Terminal coverage is verified by simulation experiments, and results show that based on the flooding method of key distribution, the update rate of mobile nodes in 81 hours reached to 90% and transmission chance of secret key in public network is reduced.
