Existing solutions are vulnerable to misbehaving users, however, who may abuse their anonymity to disrupt communication. Dining Cryptographers Networks (DC-nets) leave groups vulnerable to denial-of-service and Sybil attacks; mix networks are difficult to protect against traffic analysis; and accountable voting schemes are unsuited to general anonymous messaging.<\/jats:p>\n          <jats:p>\n            <jats:sc>dissent<\/jats:sc>\n            is the first general protocol offering provable anonymity and accountability for moderate-size groups, while efficiently handling unbalanced communication demands among users. We present an improved and hardened\n            <jats:sc>dissent<\/jats:sc>\n            protocol, define its precise security properties, and offer rigorous proofs of these properties. The improved protocol systematically addresses the delicate balance between provably\n            <jats:italic>hiding<\/jats:italic>\n            the identities of well-behaved users, while provably\n            <jats:italic>revealing<\/jats:italic>\n            the identities of disruptive users, a challenging task because many forms of misbehavior are inherently undetectable. The new protocol also addresses several nontrivial attacks on the original\n            <jats:sc>dissent<\/jats:sc>\n            protocol stemming from subtle design flaws.\n          <\/jats:p>","DOI":"10.1145\/2629621","type":"journal-article","created":{"date-parts":[[2014,8,12]],"date-time":"2014-08-12T13:53:48Z","timestamp":1407851628000},"page":"1-35","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":10,"title":["Security Analysis of Accountable Anonymity in Dissent"],"prefix":"10.1145","volume":"17","author":[{"given":"Ewa","family":"Syta","sequence":"first","affiliation":[{"name":"Yale University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Henry","family":"Corrigan-Gibbs","sequence":"additional","affiliation":[{"name":"Yale University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shu-Chun","family":"Weng","sequence":"additional","affiliation":[{"name":"Yale University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David","family":"Wolinsky","sequence":"additional","affiliation":[{"name":"Yale University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bryan","family":"Ford","sequence":"additional","affiliation":[{"name":"Yale University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aaron","family":"Johnson","sequence":"additional","affiliation":[{"name":"U.S. Naval Research Laboratory"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2014,8,15]]},"reference":[{"key":"e_1_2_1_1_1","doi-asserted-by":"publisher","DOI":"10.5555\/1760479.1760484"},{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1093\/ietfec\/e89-a.1.99"},{"key":"e_1_2_1_4_1","volume-title":"Proceedings of the 4th International Conference on Electronic Voting.","author":"Allepuz Jordi Puiggali","year":"2010","unstructured":"Jordi Puiggali Allepuz and Sandra Guasch Castello . 2010 .
