Michalas, A., Dimitriou, T., Giannetsos, T. , Komninos, N. & Prasad, N. R. (2012). Vulnerabilities of Decentralized Additive Reputation Systems Regarding the Privacy of Individual Votes. Wireless Personal Communications, 66(3), pp. 559-575. doi: 10.1007/s11277-012-0734-z
Abstract
In this paper, we focus on attacks and defense mechanisms in additive reputation systems. We start by surveying the most important protocols that aim to provide privacy between individual voters. Then, we categorize attacks against additive reputation systems considering both malicious querying nodes and malicious reporting nodes that collaborate in order to undermine the vote privacy of the remaining users. To the best of our knowledge this is the first work that provides a description of such malicious behavior against such systems. In light of this analysis we demonstrate the inefficiencies of existing protocols.
