在基于散列链密钥分配方案的基础上,对密钥池组成、密钥预分配以及对偶密钥的建立方式等进行了改进。改进后的方案能够充分利用散列链的特点,提供更加安全的网络连通性和更强的网络抗毁性。理论分析和仿真结果均验证了改进方案的有效性。
This paper based on hash chain based key distribution scheme,made some improvements on form of key pool,keys pre-distribution scheme and establishment of pair-wise key.The improved scheme could take full advantage of hash chains,provide more secure network connectivity and enhanced network survivability.Theoretical analysis and simulation results verify the effectiveness of the improved scheme.
