Mobile Ad hoc NETworks (MANETs) can be defined as a collection of large number of mobile nodes that form temporary network without aid of any existing network infrastructure or central access point. Due to the nature of MANETs to design and maintaining security is challenging task for researcher in an open and distributed communication environment. This paper, the authors proposed security architecture for MANET grid and optimal key management by combines symmetric key technique and elliptic curve public key technique. The proposed architecture and optimal key management eliminates threats including the man-in-the-middle attack and the Black hole attack can be effectively eliminated under the proposed scheme.
