A novel secure encryption using the recieved signal strength indicator (RSSI) has been proposed in this paper. RSSI signals are time variant and irregular, especially in more complicated environment. Changes of RSSI can generate a nonperiodical random number, and an attacker will hardly predict this number. Furthermore, we use this option, open cryptography algorithm, and rapid stream ciphers to construct an efficient encryption system for wireless communication network.
