AB  - An efficient and optimized secure group communication plays a vital role in 
  many emergency communication. The operations on group key management protocol 
  like joining or leaving the group dynamically and rekeying the group key when 
  changes happen in the group are performed in many protocols. In the proposed 
  system, a trust node is elected and a contributory group key is generated using 
  the 24 bit color values (RGB) that provides a secure communication of messages 
  among the group members in the dynamic environment through Diffie Hellman key 
  exchange. The proposed system also reduces the cost of rekeying the group key 
  when the mobility of the node increases. It was simulated to analyze the various 
  issues related to group key management protocols like reliability, cost of contracting 
  the group key when member join or leave the group dynamically, membership duration 
  on re-keying overhead, inter-move variation on decryption/re-encryption overhead 
  with member arrival duration. The above parameters are analyzed with respect 
  to various other group key generation protocols and results are produced. The 
  proposed system provides an optimized secure group key generation protocol for 
  MANETs.
