Mobile Ad-hoc Network (MANET) is a collection of wireless mobile nodes which dynamically forms a temporary network without the use of any existing network infrastructure or centralized administration. The security in MANETs has become a primary concern in order to provide protected communication between mobile nodes in a hostile environment. In this paper, we present the Secure Message Transmission (SMT) protocol, which safeguards the data transmission against arbitrary malicious behavior of other nodes in multipath environment. The basic idea is to transform a secret message into categories of information in multiple paths. In our study, we have found that necessity of multipath along with secure routing protocol is mandatory when the path get disconnected. We present the overall system architecture and algorithm for message dispersion and message transmission. We also consider the routing stability in MANET because its environment is more selfish. So we extended the data dispersion along with Multipath Optimized Link State routing protocol. Our simulation study shows that this approach is useful as it enhances the security in multipath routing.
