Enhancing MANET Security Using Secret Public Keys

Mobile ad hoc network (MANET) technology spreads widely in these days. It is suitable for environments that need on fly setup. A lot of challenges come with implementing these networks. The most sensitive challenge that MANET faces is the security issue. Traditional public key cryptography (PKC) and identity based cryptography (IBE) are slow and not suitable for these environments because of the nodes resources limitations. This paper is going to discuss the security of MANET using the PKI schemes in an efficient way. It will define new solution for securing MANET networks using a four keys security scheme. This solution provides a secure way for MANET nodes to authenticate each other and to secure data sent by each other.
