Anything we transmit without protection is being raid by the intruders. Hence it is necessary to impart security to the signal transmitted. In this paper we present the concept of giving security to the transmitted power signal which is to be received by a receiver in a wireless medium. The present techniques of wireless power transmission consists of a pair of strongly magnetically coupled resonators that allow power transmission of tens of watts over a few meters, but anything without security becomes unreliable. With the goal in achieving security to the power signal, we introduce the concept of encryption decryption algorithm using RF module.
