With the requirements of mobility, flexibility, and rapid response, wireless mesh networks are widely used for emergency services to improve efficiency public safety communication prevent or respond incidents that harm endanger persons property. In this paper, we propose a practical scheme key agreement with asymmetric encryption based on station-to-station protocol privacy enhanced directed signature using elliptic curve ElGamal cryptography in networks. result, only both participants can gain shared secret key, however, any party else not understand process clearly. We analyze properties security comparison encryption. The results experiment show provide resistance unknown key-share attacks, protection sensitive information included better terms computational cost.
