On Parameters for the Secure Dispersed Data Transfer Scheme Using a Multipath Routing Method

Ad hoc networks are autonomous distributed networks without the fixed communication infrastructures such as base stations. Ad hoc networks are at risk of a variety of attacks such as node capture attacks that result in tampering or leaking data. The secure dispersed data transfer method is a method to prevent node capture attacks. The performance of the dispersed data transfer method can be improved by the specific configuration of its parameters and using multiple paths with few bottleneck nodes. In this paper, we propose a configuration to maximize performance of the multipath routing method, which reduces the control packet count and reduce bottlenecking between shared elements. We have implemented our proposed method with the secure dispersed data transfer method on a network simulator, to confirm its effectiveness. In this paper, we discuss the appropriate parameters that give a promising advantage to the secure dispersed data transfer method.
