Abstract: In this Research paper we discuss the encryption technique of secret messages using One -Time Pad encryption technique accompanied with Graph Labeling. Theoretically the One – Time Pads (OTPs) are recognized as the truly unbreakable Ciphers as messages are encrypted with unique keys based on randomness thereby paving no way to “Crack the Code” when applied properly. Though OTPs have their own limitations the efficiency of this Cipher can be improved by maintaining the utmost secrecy of the ciphering key and destroying it immediately after its implementation. To add a feather to its features the encryption procedure through One -Time Pads can be further enhanced by joining hands with Graph labeling Technique. The resulting Ciphertext is represented as a Cipher Graph which is passed over to the receiver. We apply Harmonious labeling technique to this Cipher graph which together with the clue reveals the Ciphertext and the corresponding decryption yields the plaintext back. Thus cryptography clubbed with Graph Labeling technique provides absolute security of message transmission.
