Abstract

24 The rest of this paper will focus primarily on stateless BMDs, wherein the paper ballot is the only way to know the voter's intent, and where vote casting is a manual process, where the voter moves the ballot to a 20 VVSG Vol 1, Version 1.1, section 3.2.2.2, pp. 48-49. 20 For hand-marked ballots, these scanners can flag common error modes, including when a voter has indicated more than one vote in a contest which allows at most one vote (i.e., "overvoting", which can never happen with a BMD, but is possible with hand-marked paper). 58 He offers as an example an election with 20 BMDs, each of which prints 140 ballots during an election, for a total of 2800 ballots, of which 14 ballots have been altered by malware in the BMDs. For contrast, consider the paper ballot in Broward County, Florida in 2018, where the contests for U.S. Senate and Congressional Representative were placed under the long ballot instructions in the left column, leading a potentially significant number of voters to miss them entirely 11. 7 Procedures for voters to spoil their ballots vary from state to state.

Abstract

The article discusses the publication process for academic papers in computer science (CS) and provides a proposal for CSPub (clean-slate or computer science publication), an open-access publication system. The author identifies problems which he believes could be addressed by CSPub including low acceptance rates, the resubmission of rejected papers, and short incremental work which is published due to the demands of promotion and tenure systems.

Abstract

STAR-Vote is a collaboration between a number of academics and the Travis County (Austin), Texas elections office, which currently uses a DRE voting system and previously used an optical scan voting system. STAR-Vote represents a rare opportunity for a variety of sophisticated technologies, such as end-to-end cryptography and risk limiting audits, to be designed into a new voting system, from scratch, with a variety of real world constraints, such as election-day vote centers that must support thousands of ballot styles and run all day in the event of a power failure. This paper describes the current design of STAR-Vote which is now largely settled and whose development will soon begin.

Abstract

International audience; POST is a decentralized messaging infrastructure that supports a wide range of collaborative applications, including electronic mail, instant messaging, chat, news, shared calendars and whiteboards. POST is highly resilient, secure, scalable and does not rely on dedicated servers. Instead, POST is built upon a peer-to-peer (p2p) overlay network, consisting of participants' desktop computers. POST offers three simple and general services: (i) secure, single-copy message storage, (ii) metadata based on single-writer logs, and (iii) event notification. We sketch POST's basic messaging infrastructure and show how POST can be used to construct a co-operative, secure email service called ePOST.

98. Web Spoofing: An Internet Con Game

Author

Balfanz, Dirk ., Dean, Drew., Felten, Edward W., Wallach, Dan S., Balfanz, Dirk ., Dean, Drew., Felten, Edward W., and Wallach, Dan S.

Abstract

The Safe Internet Programming group at the Princeton University Department of Computer Science in 1996 published a paper on the practice known as "web spoofing," through which an attacker intervenes between an end-user browsing the Web and real Web sites. The attacker sets up a shadow copy of the Web, and as users request pages from sites they will receive pages from the attacker's site instead. This process also enables attackers to gather data (possibly credit card numbers, etc.) submitted through bogus web forms. The nine-page paper describes how the con game works and suggests remedies. The article is available in PostScript, compressed PostScript, Microsoft Word, and zipped Microsoft Word format. Unfortunately, it is not available online as HTML.

99. A Taxonomy of Rational Attacks.

Author

Castro, Miguel, Renesse, Robbert, Nielson, Seth James, Crosby, Scott A., and Wallach, Dan S.

Abstract

For peer-to-peer services to be effective, participating nodes must cooperate, but in most scenarios a node represents a self-interested party and cooperation can neither be expected nor enforced. A reasonable assumption is that a large fraction of p2p nodes are rational and will attempt to maximize their consumption of system resources while minimizing the use of their own. If such behavior violates system policy then it constitutes an attack. In this paper we identify and create a taxonomy for rational attacks and then identify corresponding solutions if they exist. The most effective solutions directly incentivize cooperative behavior, but when this is not feasible the common alternative is to incentivize evidence of cooperation instead. [ABSTRACT FROM AUTHOR]

100. Scrivener: Providing Incentives in Cooperative Content Distribution Systems.

Author

Alonso, Gustavo, Nandi, Animesh, Tsuen-Wan "Johnny" Ngan, Singh, Atul, Druschel, Peter, and Wallach, Dan S.

Abstract

Cooperative peer-to-peer (p2p) applications are designed to share the resources of participating computers for the common good of all users. However, users do not necessarily have an incentive to donate resources to the system if they can use the system's services for free. In this paper, we describe Scrivener, a fully decentralized system that ensures fair sharing of bandwidth in cooperative content distribution networks. We show how participating nodes, tracking only first-hand observed behavior of their peers, can detect when their peers are behaving selfishly and refuse to provide them service. Simulation results show that our mechanisms effectively limit the quality of service received by a user to a level that is proportional to the amount of resources contributed by that user, while incurring modest overhead.
