Encryption and Decryption of Data Using Edge Bimagic Mean Labeling and Hill Cipher Technique

In the past few decades, a technology for encrypting and decrypting messages using the hill cipher crypto system and graph labeling technique has emerged. While considering two symmetric cipher types namely substitution cipher and transposition cipher, Hill cipher is a type of substitution cipher used for encrypting a group of letter. In this research, a labeling concept namely Edge Bimagic Mean Labeling has been introduced and it is substantiated for the ladder related graphs. The encryption process and the decryption process of a text using Hill cipher are also analyzed by making use of the same labeling technique.
