摘要

随着航天技术的不断发展，航天器之间的通信日益增多。时间同步协议对航天器保持统一的时间标准起着至关重要的作用。针对深空链路质量差、节点计算能力有限、GNSS服务不稳定等特点，通过对IEEE1588协议的改进，提出了一种不依赖GNSS服务，安全安排相对完善的空间环境自主时间同步协议——空间安全增强型IEEE1588 (SEIEEE1588)。

A Security Enhanced IEEE1588 Protocol for Deep-Space Environment

With the continuous development of the space technology, increasing communication between spacecrafts. To ensure the spacecrafts keep a uniform time standard, time synchronization protocol plays an crucial role. Taking account the characteristics of deep-space: poor link quality, limited node computing power, and the GNSS service is unstable, through the improving of IEEE1588 protocol, a autonomous time synchronization protocol for the space environment is presented, which security arrangement is relatively sound, does not depend on the GNSS service - Security Enhanced IEEE1588 for Space (SEIEEE1588).
