An Elevated Trust-based Security for Mobile Ad-hoc Networks
Since mobile ad-hoc networks always applies in those situations such as emergencies,crisis management,military and healthcare,so message security is of paramount importance in it.However,because of the absence of a fixed infrastructure with designated centralized access points, implementation of hard-cryptographic security is a challenging prospect.In this paper,we propose a novel method of message security using elevated trust-based routing.Less trusted nodes are given lower number of self-encrypted ,parts of a message,making it difficult for malicious nodes to gain access to the minimum information required to break through the encryption strategy.Using trust levels,we make multi-path routing flexible enough to be usable in networks with vital nodes and absence of necessary redundancy.In addition,using trust levels,we avoid non-trusted routes that may use brute force attacks and may decrypt messages if enough parts of the message are available to them.Simulation results,coupled with theoretical justification, affirm that the proposed solution is much more efficient than the traditional routing algorithms.
