Space key management schemes play a critical role in space information network security services. However, the existing space key management schemes are inefficient. To overcome these problems, this paper proposed a cluster group key management scheme, in which the space nodes are divided into different clusters. The ground control center (GCC) is used as a private key generation center. The threshold technique based on low-density parity-check code (LDPC) is used in the group key management of the cluster-heads. The key escrow is transferred to GCC, which is a compromise of efficiency and security. The logical key hierarchy is used to manage the group key of the cluster. Furthermore, the bilinear paring-based cryptosystem is employed to provide the identification. The formalized security proof of the protocol using the Extended Canetti–Krawczyk (ECK) model is introduced to prove the authentication and security. The consistency, forward secrecy, backward secrecy, ability to against the collusion attack and performance are analyzed and simulated. The result shows that the proposed scheme takes lower storage cost and computational cost.

基于阈值秘密共享和双线性对的集群空间密钥管理方案

空间密钥管理方案在空间信息网络安全服务中发挥着关键作用。然而,现有的空间密钥管理方案效率低下。针对这些问题,本文提出了一种集群组密钥管理方案,将空间节点划分为不同的集群。地面控制中心(GCC)用作私钥生成中心。基于低密度奇偶校验码(LDPC)的阈值技术用于簇头的组密钥管理。密钥托管转移到 GCC,这是效率和安全性的妥协。逻辑密钥层次结构用于管理集群的组密钥。此外,采用基于双线性配对的密码系统来提供标识。引入了使用 Extended Canetti-Krawczyk (ECK) 模型的协议形式化安全证明来证明身份验证和安全性。对一致性、前向保密性、后向保密性、抗共谋攻击能力和性能进行了分析和仿真。结果表明,所提出的方案具有较低的存储成本和计算成本。
