Trust Based Security in Battlefield-of-Things

Abstract

Trust evaluation is an alternate security field, which does not follow the traditional domain of cryptography and its allied mechanisms. Trust is important in any Self-Organising Network (SON) and applicable to mission critical systems where the emergence of system-wide adaptive structure in adhoc deployment and functionality from simple local interactions between individual entities is paramount. Transactions are thus collaborative for control and data transfers. Battlefield-of-Things (BoTs) is a use-case which demonstrates deployment of collaborative wireless sensor network, extensible to employ the Internet of Things. Trust evaluation mechanisms are applied in this work in BoTs to achieve secure transactions in hostile environment. The work proposes a distributed Agent based Trust Evaluation for BoTs. The work addresses the heterogenity of BoTs and the multimodal sensor approach in the battlefield along with the issue of adversary BoT participating in network transactions; hence only a benign BoT is allowed to participate in network operations. Transacting BoTs evaluate trust for all sensitive data transfers thereby demonstrating data trust.
