Presently in mobile networks the energy preservation is an important issue especially in group communication. Another important factor is to prevent the possible attacks in that communication. To address the above issues in the group communication, we proposed a novel efficient heuristic algorithm called High Diffusion (HD) code with high security. By generating an active 288 bits key protocol using the Key Generation Hub (KGH) for the HD cipher encryption the high security and the confidentiality of the transformation can be achieved. This protocol is based on secret sharing scheme that KGH can broadcast information to all the members in that cluster at once and only the authorized group members can recover the group key.
