Recent trends and growth in Network and Internet Technology create unbelievable transaction in communication methodology. Distributed and Parallel Processing are the mile stones for network growth. Since technology has been developed, it is mandatory to take care of implementation difficulties. Installation Cost, Development Issues, Security Issues, Reliable Analysis and Resource Management are the major areas to do the research in implementation. Group Communication (GC) model is applied in most of the Distributed and Parallel Processing system. To provide security services, key based cryptography approaches are applied. Encryption key is dynamically changed in associate with the change in the group strength. Huffman code is used to regenerate the group key at minimum cost.
