Nowadays, the use of digital technology for communication is constantly growing.As a result, algorithms that provide more secure communication must be employed.Despite the fact that there are numerous encryption algorithms, app developers are constantly looking for a new or updated versions of the algorithms.In this proposed work, the vertex odd mean labeling method is used to produce edge values for a graph that serve as the encoded numbers for the characters of a plaintext.The complement of that graph is taken to generate a cipher graph.Communication will be safer since each text will have a distinct cipher graph.The text is encrypted and decrypted using the symmetric key technique.This algorithmic approach is useful for all texts with or without special characters.
