【摘要】 随着国际空间任务的交叉合作以及互联网在空间任务中的应用,空间数据安全性受到威胁,空间数据的加密日益受到设计人员的重视。CCSDS于2004年推荐AES算法作为空间数据系统的加密标准。本文根据高速数据处理的实际需求,采用了在FPGA上实现AES算法的数据加密方案,仿真结果表明,AES是一种优选的加密算法,能够满足高保密性、加密速率快、硬件资源占用少等任务要求。更多还原

【Abstract】 Civil space mission and ground system developers must now consider the security of space data with the advent of more open systems for increased Internet connectivity, and cross support activities. AES was recommended as the encryption standard for space data system by CCSDS in 2004. In this paper, AES is implemented on FPGA on the basis of system specifications. It is proved that AES could meet the high level security, high speed process, and less hardware resource occupation requirements of missions.更多还原
