摘要: 基于对称密码体制的密钥管理方案的关键是取得安全与性能的平衡。针对卫星网络节点资源受限的特点, 提出了按照随机矩阵分配节点密钥元素的方法。该方法简化了密钥环的构造,而且能够确保任意节点之间可建立互 不相同的会话密钥。给出了相应的密钥更新机制。仿真结果表明,该方法能够在保证安全性的同时显著降低密钥存 储与计算开销。

Abstract: To key management scheme based on symmetrical cryptographic system, it is crucial to get balance of securi- ty and performance. According to satellite network nodes resource constraints, a key elements distribution method was introduced based on random matrix for nodes. It simplified the construction of key rings, and can make sure that any node can establish different session keys with different other nodes. Then we gave the corresponding key update mecha- nism The simulation results show that this method can guarantee security and reduce storage and computing cost by keys significantly at the same time.
