摘要
本文介绍了导航信号加密认证技术的分类和优缺点比较,对目前常用的两种导航电文加密(NMA)方法 ECDSA和TESLA的原理进行介绍,并对两种方法进行了比较分析,详细介绍了欧洲Galileo和美国GPS导航系统的导航电文加密方法研究的相关背景和主流设计思想,随着卫星导航系统的不断发展,导航民用信号的安全性必将越来越受到导航系统拥有国以及研究者的关注。
This paper introduces the classification of the navigation signal authentication technology, introduces the two methods of navigation message authentication （NMA）, ECDSA and TESLA, which are commonly used, and compares and analyzes these two methods. This paper analyze the research background and mainstream design ideas of the navigation message authentication method of the Galileo navigation system from Europe and the GPS navigation system from the United States. With the continuous development of the world satellite navigation system, civil navigation security will be more and more concerned by the countries have the navigation system and the researchers.
