Abstract: The hopping pattern is one of the key technologies of frequency hopping communication system, which directly affects the security of the frequency hopping communication system, so design a good hopping pattern is particularly important. In order to enhance the security of the frequency hopping system, this paper proposes wide interval frequency hopping pattern based AES encryption algorithm RS codes. The performance analysis shows that the frequency hopping pattern not only with password features, but also has a good correlation between the frequency and the spacing between adjacent significantly increased.
