【摘要】：随着航天技术、移动通信技术和网络技术的迅速发展以及信息化建设的逐渐深入,空间信息系统也在向着网络化的趋势加速发展,其应用前景受到了极大的关注,故其对安全的要求越来越高。文中提出的基于身份的空间网络组密钥管理方案ID-GKM中,采用分层分组式的组密钥管理机制,方案除了包括常有的组密钥生成分发、密钥更新外,还考虑了私钥更新。在私钥更新部分,采用BF提出的基于身份的公钥加密机制,提出了适合空间网络的私钥更新机制。该方案能够适应空间网络的层次化架构,满足其对强扩展性、高可靠性等的要求。另外,针对地面终端节点与空间节点不同的特点,提出地面组管理的密钥更新应采用批量更新的方案,该方案结合使用了定期和基于队列更新的思想,且可以考虑采用基于代理重加密的组密钥管理方案来解决LKH方案中组密钥更新时对用户必须在线的要求。
[Abstract]:With the rapid development of space technology, mobile communication technology and network technology, and the gradual deepening of information construction, the spatial information system is accelerating towards the trend of networking. Its application prospect has been greatly concerned, so its demand for security is higher and higher. In this paper, a group key management scheme based on identity is proposed in ID-GKM. A hierarchical grouping group key management scheme is adopted. Besides regular group key generation, distribution and key update, the scheme also considers private key update. In the part of private key update, the private key updating mechanism suitable for space network is proposed by using the identity based public key encryption mechanism proposed by BF. The scheme can adapt to the hierarchical architecture of space network, and meet its requirements for strong expansibility, high reliability and so on. In addition, according to the characteristics of the ground terminal nodes and nodes of different space, put forward the ground group management key update should adopt the batch update scheme, this scheme uses a combination of regular and queue updates based on the idea, and you can consider using proxy re encryption of the group key management scheme based on LKH scheme to solve the user must online group key update request.
