摘　　要：分析了PRS服务的安全架构,包括信号加解密、PRS安全模块、PRS密钥管理设施和PRS管理框架。详细阐述了PRS拓展密钥与辅助信息分发渠道而采用的二级通道技术,介绍了常规接收机和基于服务器的接收机2种PRS接收机结构并进行对比,最后介绍了PRS用户段相关研究。In this paper, we analyzed the security architecture of PRS service, including signal encryption and decryption, PRS security module(SM), PRS key management infrastructure and PRS regulatory framework. Then, we illustrated the use of secondary channel by Galileo as an alternative means to support PRS key update. Finally, we described and contrasted two major PRS receiver architectures, namely the regular one with SM and the remote server based one without SM. The PRS user segement preparing work is also outlined.
