|
摘要
为实现卫星移动通信数据传输,并改善数据传输的安全性,文章提出了应用数字签名机制的卫星移动通信数据传输方案。该方案结合地球静止轨道卫星移动通信接口标准第2版(GMR2)的通信机制,通过在数据帧中增加同步位解决数据传输过程中的同步问题,利用增加状态位和同步位的方式实现2.4kbit/s到3.0kbit/s的数据率转换,同时引入数字签名机制,提前验证通信双方身份的可靠性,进一步保证数据安全传输。通过设计实例和测试方案验证了数据传输方案的有效性。结果表明,该方案能保证数据在卫星移动通信网络中安全传输,可为卫星移动通信数据传输研究提供参考。
In order to realize and improve the security of data transmission for satellite mobile services,this paper designs and implements a scheme of data transmission with signature mechanism for satellite mobile services.It is combined with communication mechanism of satellite mobile communication system based on GMR2(GEO Mobile Radio Interface 2).It uses synchronous bits to ensure the sychronization during transmission,and adds status bits and synchronous bits to achieve data rate transformission from 2.4 kbit/s to 3.0 kbit/s.It is introduced signature mechanism which verifies the identities of both parties and improves the security of data transmission.The validity of the scheme is verified by the example design.The results indicate that the scheme is useful for secure of data transmission for satellite mobile services and provides an reliable reference for data transmission research of satellite mobile services.
