Double Split Based Secure Multipath Routing in Adhoc Networks

The security in mobile ad hoc networks (MANETs) is a serious concern. This article presents a new approach namely the double split (DSPLIT) for enhancing the security features in MANET. The basic idea is to transform a secret message into categories of information and dictionary symbols. The information symbols are further splitted and delivered via multiple paths to the destination while as a position table is generated based on the dictionary symbols and the same is sent through a single path. The purpose of doing so is to provide an additional security against the adversaries that collect many shares, which leads to message reconstruction. We present the overall system architecture and discuss the model for the generation of information and dictionary symbols, position table formation and finally further dividing information symbols and allocating them to their corresponding multipaths. Our simulation study shows that this approach is useful as it enhances the security and consumes less bandwidth.
