![]() WSEmail’s architecture, especially its automatic plug-in download feature, allows for rich extensions without changing the base protocol or libraries. WSEmail offers an alternative vision of how instant messaging and email services could have evolved, offering security, extensibility, and openness in a distributed environment instead of the hardened walled gardens that today’s rich messaging systems have become. In this work, we revisit WSEmail, a system proposed over 10 years ago to improve email by redesigning it as a family of web services. Web services offer an opportunity to redesign a variety of older systems to exploit the advantages of a flexible, extensible, secure set of standards. Running our ConScript prototype JavaScript client generates a dummy message forĪ mix-net in 81 milliseconds and it generates a dummy message for aĭoS-resistant DC-net in 156 milliseconds. Implementation results demonstrate the practicality of ConScript: a workstation We discuss the ethical issues related to deploying such a system. We outline ConScript'sĪrchitecture, we address a number of potential attacks against ConScript, and Verifiable shuffle-style anonymity systems. Increase the anonymity set size available to users of remailer, e-voting, and Creating such conscripted anonymity sets can Messages through the anonymity system use a browser plug-in to replace theseĭummy messages with real messages. "dummy" messages into the anonymity system. Serves a JavaScript application that instructs the browser to create and submit ![]() ![]() When a Web user visits a cooperative Web site, the site We present the design and prototype implementation of ConScript, a frameworkįor using JavaScript to allow casual Web users to participate in an anonymousĬommunication system. We will detail approaches for implementing a variety of features required for user productivity in a manner that satisfies user-defined privacy concerns. The paper presents CryptPad, an open-source reference implementation which features a variety of editors which employ the described access control methodology. This system separates access to the information ("the key") from the responsibility of hosting the content ("the carrier of the vault"), allowing privacy-conscious editors to enjoy a modern collaborative editing experience without relaxing their requirements. Encryption keys are distributed as the portion of a URI which is not shared with the server, enabling users to adopt a variety of document security workflows. We describe a novel scheme for collaborative editing in which clients enforce access control through the use of strong encryption. ![]() Traditionally, access control policies have been enforced by a central authority, usually the server hosting the content, a single point of failure. However, collaboration via the web has shown a tendency to centralize information, making it accessible to subsequent uses and abuses, such as surveillance, marketing, and data theft. The World Wide Web and other communication means have contributed to this evolution. Of making encrypted instant messaging accessible and portable.ĭocument editing has migrated in the last decade from a mostly individual activity to a shared activity among multiple persons. Highly accessible mediums, and to address the technical and social challenges Goal is to investigate the feasibility of implementing cryptographic systems in Privacy is not achieved without addressing the problem of accessibility. If a cryptographic system is technically highly qualified, securing user That accessibility and ease of use must be treated as security properties. ![]() We have found that encrypted communications, while in manyĬases technically well-implemented, suffer from a lack of usage due to theirīeing unappealing and inaccessible to the "average end-user". Order to allow encrypted instant messaging an opportunity to better permeate onĪ social level. We aim to investigate how toīest leverage the accessibility and portability offered by web technologies in Makes use of web technologies in order to provide easy to use, accessible,Įncrypted instant messaging to the general public. Cryptocat is a Free and Open Source Software (FL/OSS) browser extension that ![]()
