This paper presents a constellation symbol obfuscation design approach is to fix the shortcomings that the change of secret key is limited and the key sharing process is not confidential. We treat the channel phase between the sender and the legitimate receiver as secret key to realize multi-change of secret key’s phase. We adopt conditions of time division duplex mode and channel reciprocity criterion to realize no key sharing. This paper uses SER to evaluate the security performance of the system. Aiming at the random attack mode of eavesdroppers, analyze and simulate the eavesdroppers’ performance.
