摘　　要：针对现有的动态密钥种子分配方法,存在密钥种子分配安全性较差、平均能耗较大、速度较慢等问题,提出基于混沌映射的云存储动态密钥种子分配方法,该方法首先需要构建一个基于混沌序列的动态密钥模型,然后将构建的动态密钥模型分成网络密钥种子和会话密钥种子,最后通过动态密钥种子部署、动态密钥种子安全簇建立、数据传输和密钥更新四个阶段,实现对云存储动态密钥种子的分配。仿真结果表明,所提方法能够在高安全性、低平均能耗的情况下,实现对动态密钥种子的分配,且分配速度较快,能够满足对动态密钥种子分配速度的需求。Due to poor security of key seed distribution, high average energy consumption and slow speed of current methods, this paper puts forward a method to allocate the cloud storage dynamic key seeds based on chaotic mapping. Firstly, this method needed to construct a dynamic key model based on chaotic sequence, and then the constructed dynamic key model was divided into the network key seed and session key seed. Through the dynamic key seed deployment, the establishment of dynamic key seed security cluster, data transmission and key update, the allocation of cloud storage dynamic key seeds was achieved. Simulation results show that the proposed method can realize the allocation of dynamic key seeds with high security and low average energy consumption. Meanwhile, the allocation speed is fast and the requirement of dynamic key seed allocation speed can be satisfied.
