Secure communication is when two entities are communicating and do not want a third party to listen in. For that, they need to communicate in a way not susceptible to eavesdropping or interception. Two varieties of security mechanism, cryptography and steganography are being applied. At the preceding stage, encryption is being provided to secret plain text using Vernam cipher (One-Time Pad) transposition technique. At the later stage, it transforms ciphertext into bytes and divides each byte into pairs of bits and assigns the decimal values to each pair, which is known as a master variable. Master variable value range will vary between 0 to 3. Depending upon the master patchy value, add that cipher text in the career image at Least Significant Bit (LSB) 6 th and 7 th bit location or 7 th and 8 th bit location or 7 th and 6 th or 8 th and 7 th bit location. Vernam cipher show good performance metrics regarding less CPU running time, fIle size same after Encryption and strong avalanche effect compare with all transposition cipher. After completion of embedding and sending the stego image to the receiver side, retrieving process of the cipher text from the said locations will be done. Moreover, then decryption process to get the secret plain text back will be performed using the Vernam cipher transposition algorithms.
