With the continuous development and increasing popularity of satellite networks, more and more countries and researchers are focusing on proposing communication solutions for satellite networks. The space-terrestrial integrated network (STIN) concept is proposed for terrestrial users to communicate with satellite networks. STIN is mainly composed of a space-based backbone network, a space-based access network, and a terrestrial backbone network to provide services for all types of space-based users, aviation-based users, marine-based users, and land-based users. For instance, marine-based users often encounter sudden accidents in distant oceans, which may need emergency rescue with the help of STIN. The emergency data involved in the rescue is often users' private data and needs to be protected. In this article, we propose a novel secure emergency data protection scheme for such users in a STIN. The novel scheme is composed of three phases: emergency data transmission, group block-design- based key agreement, and secure satellite information acquisition. The performance analysis shows that the novel scheme is secure and efficient.

天地一体化网络安全应急数据保护方案


随着卫星网络的不断发展和日益普及，越来越多的国家和研究人员开始致力于提出卫星网络的通信解决方案。天地一体化网络（STIN）概念是为地面用户与卫星网络通信而提出的。 STIN主要由天基骨干网、天基接入网、地面骨干网组成，为各类天基用户、航空用户、海洋用户、陆基用户提供服务。用户。例如，海上用户经常会在遥远的海洋中遇到突发事故，可能需要借助STIN进行紧急救援。救援中涉及的应急数据往往是用户的隐私数据，需要受到保护。在本文中，我们为 STIN 中的此类用户提出了一种新颖的安全紧急数据保护方案。该方案由紧急数据传输、基于组块设计的密钥协商和安全卫星信息获取三个阶段组成。性能分析表明该方案安全、高效。
