Abstract: Due to their applications in situations such as emergencies, crisis management, military and healthcare, message security is of paramount importance in mobile ad-hoc networks. However, because of the absence of a fixed infrastructure with a designated centralized access points, implementation of hard-cryptographic security is challenging. In this talk, I will discuss the different issues and challenges underlying the problem of message security in mobile ad-hoc networks and we propose a novel method of message security using trust-based multi-path 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 minimun 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.
