Code modulation based encryption & descryption technique for secure communication in wireless

  1. 1. CODE MODULATION BASED ENCRYPTION & DECRYPTION TECHNIQUE FOR SECURE COMMUNICATION IN WIRELESSABSTRACTIn Today’s Electronic communication take important role. Today’s Communication technologythe chatting system from one Place to another is easy and fast. But security is of some concern,for that we send the data by the system named as Advanced chatting system usingMicrocontroller.In our project we have two sections, one is transmitter section and another one is Receiversection. The two sections are designed around a microcontroller as a control unit with all thedevices interfaced to it. The main aim of the project is to transmit the data using wirelesscommunication by encrypting the data. At the receiver side, the encrypted data is decrypted andis shown in the PC.According to this project the person who wants to send the data to a remote place has to type thedata from the PC. The data is received by microcontroller and is sent to RF transmitter afterencrypting it. The RF receiver receives the data decodes it and displays the encrypted data inPC. If the actual data is to be viewed then a password is to be pressed. Now the cipher text isconverted into plaintext.
