    Abstract: In this study we used standard groups and Hosoya polynomial to implement Diffie-Hellman method
to generate matrix key cryptosystem instead of the number which is generate as a key in this method. Also, we
using Dihedral group with Hosoya polynomial for group graph to encrypt plain text and to decrypt cipher text
and we produce the statistical table for the ratio to any letter in plain text and every letter in cipher text.
