Abstract: In the absence of a centralized coordinating authority, peers in decentralized applications interact directly with each other and make local autonomous decisions. Open decentralized systems do not regulate the entry of peers into the system making peers susceptible to the potential attacks of malicious peers. Trust management solutions serve to provide effective protective measures against such malicious attacks. However, research in trust management has given little focus to how trust models can be composed into a decentralized architecture. The PACE (Practical Approach for Composing Egocentric Trust) architectural style provides structured and detailed guidance on the assimilation of trust models into a decentralized entity's architecture. This poster describes our experiments with incorporating four different reputation-based trust models into a crisis response decentralized application using the PACE architectural style.
