摘　　要：跳频通信技术因为具有较好的抗干扰和低截获性能,在军事通信中占有重要的地位,因此提高系统的保密性有着很重要的意义.为了提高保密性,提出了两种提高系统保密性的方法,其核心思想是将加密算法应用到跳频系统,分别在跳频通信系统发送端和接收端进行加密和解密.理论分析和仿真结果表明,该算法不仅充分的利用了信源加密算法,而且有效提高了系统的安全性.Hopping communication technology, because of its better anti-interference and low interception performance, occupies an important position in the military communications. Therefore, it is important to improve the confidentiality of the system. Two algorithms were proposed in this paper to achieve the confidentiality, whose core ideas were introduced the eneryption technologies into the frequency-hopping system, and made the encryption and de- cryption on the transmitter and receiver. Theory and simulation analysis result showed that these algorithms not only used the encryption algorithms effectively, but also highly improved the security of the system.
