摘要
随着卫星通信技术的发展,语音通信成为其主要的服务内容,基于卫星的语音通话安全问题日益受到关注。欧星电话是由萨拉亚(Thuraya)提供的卫星和GSM双模移动电话,在分析其通信安全问题的基础上,设计并实现了一种应用于欧星电话的端到端加密系统。该系统基于STM32F405RG芯片设计完成,软件部分采用了基于频域置乱的加密算法。软件仿真和实验测试表明,该系统具有良好的保密效果。
With the development of satellite communication technology,voice communication has become its main service,and the security issues have received increasing attention. Eurostar phone is a dual-mode mobile communication system consisting of satellites provided by Thuraya and GSM. Based on analysis of its communication security issues,this paper designs and implements an end-to-end encryption system for Eurostar phones. The system is implemented based on the STM32 F405 RG chip,and the software is designed by using an encryption algorithm based on frequency domain scrambling.Simulations and experiments verify the security of the proposed algorithm and system.
