With the development of mobile internet, wireless communications via mobile devices in the form of Delay Tolerant Networks (DTNs), becomes a hot research topic. One critical issue in the DTNs with social characteristics is that there could exist selfish nodes which are unwilling to forward messages from strangers and malicious nodes which intentionally impair normal communication. Although there are a lot research works addressing various issues in the DTNs, most current research works only take communication behavior into account. In view of these defects in the existing works, we propose a novel solution to address the selfish and security issues in the social DTNs. A dynamic trust model is proposed to prevent bad-mouthing and ballot stuffing attacks and the Shannon entropy function is introduced to avoid blackhole and greyhole attacks. The simulation results show that our proposed scheme can significantly improve the performance of the social DTNs.
