Aiming at the problem that the two-dimensional uniformity of the frequency hopping pattern in differential frequency hopping communication is poor. and the frequency hopping frequency is easy to be eavesdropped. this paper designs an encryption scheme based on the pseudo-random sequence of logistic chaotic map to randomly scramble the frequency hopping pattern.
