摘要
随着无线通信和信息安全技术的飞速发展,人们对无线实时图像传输的保密要求越来越迫切。无线通信由于受其信道和带宽的限制、密码同步码的插入,将会增加无线信道的信息载荷,降低无线信道的通信效率,造成密码通信失败或通信质量严重降低。针对实时图像传输保密通信系统强实时性和通信质量要求高的特点,研究无线通信系统中密码同步方法,采用独特的密码同步码的插入技术,提高图像传输保密通信的安全性和可用性。
With the rapid development of wireless communication and infosec technologies, the demand for secure video transmission becomes even more urgent, and video security also becomes a hot-spot in scientific research field. Since wireless communication is limited by its channel and bandwidth, the information payload of wireless channel be increased and the communication efficiency of the wireless channel be downgraded with the insertion of crypto synchronous codes, this may probably impair the communication quality or even cause serious communication failure. In accordance with the characteristic the real-time image secure communication system, this paper proposes a novel method of inserting crypto synchronous codes, which could effectively improve the security and availability of real-time wireless image secure communication.
