MoP-2-MoP - Mobile private microblogging.
Conference or Workshop Item
Abstract
Microblogging services have become popular, especially since smartphones made them easily accessible for common users. However, current services like Twitter rely on a centralized infrastructure, which has serious drawbacks from privacy and reliability perspectives. In this paper, we present a decentralized privacy-preserving microblogging infrastructure based on a distributed peer-to-peer network of mobile users. It is resistant to censorship and provides high availability. Our solution allows secure distribution of encrypted messages over local radio links to physically close peers. When redistributing messages, each peer rerandomizes encryptions to achieve unlinkability. Moreover, we show the feasibility of our solution using different synchronization strategies.
