Abstract: In this paper, we design plaintext through product edge labeling for a Cyclegraph. The edge labels thus obtained is further processed through Caesar cipher method. The ciphertext thus obtained is subjected to Bifid Cipher for which we apply matrix multiplication. The decryption is performed using Inverse matrix multiplication and subsequent application of Bifid cipher and Caesar Cipher yields our plaintext. This methodology is considered highly efficient and secure as it combines Cryptographic technique together with Graph Labeling thereby making it difficult for any Adversary to hack the plaintext. We investigate the above technique using Non- singular square matrices.
