Double Encryption, Decryption Process Using Graph Labeling Through Enhanced Vigenere Cipher

Abstract

In this paper, we promote Double encryption process of our secret text initially through Difference Labeling of Signed Graphs and then through the Vigenere Cipher technique. Thus we propose Double encryption and their corresponding decryption process thereby making prediction of secret text complicated.

Encoding And Decoding Process Using Prime Graceful Labeling

“…The original secret text from the sender to the receiver which requires to be transformed into some version is called Plaintext. Definition 3: [3] The required version of our Plaintext is called Ciphertext. Definition 4: [3] The process of transforming Plaintext to Ciphertext is called Encryption.…”

“…Definition 3: [3] The required version of our Plaintext is called Ciphertext. Definition 4: [3] The process of transforming Plaintext to Ciphertext is called Encryption. Definition 5: [3] The transformation of Ciphertext to Plaintext is termed as Decryption.…”

“…Definition 4: [3] The process of transforming Plaintext to Ciphertext is called Encryption. Definition 5: [3] The transformation of Ciphertext to Plaintext is termed as Decryption. Definition 6: [3] The essential tool that encodes the Plaintext and also decodes the Cipher text is called Key.…”

An Improved Encryption Process using One-Time Pad Together with Graph Labeling

“…For some basic terminologies on Graph labeling we refer [1]. In [2] our work on double encryption process using Graph labeling through enhanced Vigenere Cipher Technique encouraged us to carry out some more research in this area with slight variations and our current work is one among them. Further from [9] the idea of introduction of Cipher Graphs to transmit secret message to the receiver has greatly motivated our current work in connection with Graph Labeling.…”

“…Fan Graph f 8 and Friendship Graph F 4 are harmonious by [2].Our Cipher Graph is a combination of Fan Graph and Friendship Graph is the Cipher message to which the receiver applies Harmonious Labeling to find the edge labels with the help of Cipher clue…”
