Risultati finali Documents, reports (25) Applying Mix Nets to Email Document This report will present the use-case and requirements, based on empirical data, of the mix networking infrastructure, with a focus on usability, a mathematical analysis of the privacy set, and threat models. Complete Exploitation Plan We will update D2.5 with exploitation activities already performed including definition of business models for market adoption of results of the project. Minimum Viable Product (MVP) A functional, deployable, and demonstrable mix-net service implemented according to results and requirements from WP3, WP5, WP6 and WP7. Report on Exploitation Activities and Updated Plan for Further Exploitation Final update of the exploitation plan will be presented and a list of exploitation activities performed during the last year of the project will be reported. Requirements and User Interface Design Documents including a first version of the evotingsystem Initial report Modelling and Design elements. Describes some of the existing shuffle protocols (WP3.2), initial design options for mix-nets (WP3.1) and definitions of privacy (WP3.3) Dissemination Report I Dissemination reports will be delivered each year and the dissemination plan will be updated if necessary. Survey/Statistics: Interim report Interim report including requirements analysis and initial design. This report will describe the results of the requirements analysis and outline the initial design used to start the implementation. Modelling, Design and Analysis:Interim report First iteration of a NIZK shuffle proof. Describes the shuffle protocol that may be used in implementation within WP5; Integrates robustness into efficient mix-net designs and decryption mixes; proposes robust definitions of mix-nets as differentially private mechanisms Final Review and Assessment This deliverable will review and assess the activities, results, and progresses of Y3. This will provide a basis for each consortium member to engage in further EU projects with increased performance and efficiency. Dissemination Plan A dissemination plan will be outlined, where dissemination activities via various channels will be planned as described in Task 2.1. Final report validation & testing This report will summarize the results of the validation and testing including lessons learned. It will provide guidance to future adopters of the system. Integrated System A fully integrated, tested, and documented system, incorporating any updated requirements and designs from the experience of the MVP that can be disseminated. Y1 Review and Assessment This deliverable will review and assess the activities, results, and progresses of Y1. This will provide a basis for moving into Y2 and examine where the consortium was successful and where improvements are needed for the following year. Final report Final iteration of the NIZK shuffle proof together with security analysis, and an implementation; validation of mix-net design options and refinement of definitions to suit other WPs Standardisation Report The standardization-related efforts and achievements will be collected in this report. Y2 Review and Assessment This deliverable will review and assess the activities, results, and progresses of Y2. This will provide a basis for moving into Y3 and examine where the consortium was successful and where improvements are needed for the following year. Ethics report The ethics report details all procedures that will be implemented for data collection, storage, protection, retention and destruction and confirmation of personal information by Panoramix partners. Copies of ethical approvals by the competent Ethics Committee and copies of approvals for the collection of personal data by the competent University Data Protection Officer / National Data Protection authority will be included, and in case of data not publicly available, relevant authorisations will also be provided if applicable. This deliverable will also contain templates of the informed consent form to be used. Scientific Advisory Board Reports After each EAB meeting EAB will write a report with observations, recommendations and conclusions on actions for increasing the project impact. A summary of all reports will be compiled at the end of the project. Dissemination Report II Dissemination reports will be delivered each year and the dissemination plan will be updated if necessary. Dissemination Report III Dissemination reports will be delivered each year and the dissemination plan will be updated if necessary. Preliminary Exploitation Plan In this deliverable the first version of exploitation plan will be presented. It will be aligned with the consortium partners’ business plans and market evaluation. Analysis of User Feedback Based on the user feedback from the deployment of mix networking with email, we will determine whether or not users found the privacy sufficient. This report will also include the feedback from the living lab research, where the mobile message app is tested with 1000 test users. Final System A production-ready system and a corresponding internet service incorporating any external feedback and addressing any remaining integration issues. Initial Requirements, Design, and Prototype The first version of the system that addresses basic concerns in all three tasks that do not depend on other work packages, requirements addressing the state-of-the-art industry environments, design addressing development methodology and tools, and prototype addressing development, deployment, and the testing environment. Other (3) Open-source code of integrated system for desktops This deliverable, available as code on GitHub with a brief developer guide to the code, will allow system administrators to deploy the mixnetworking infrastructure for email, with clients for desktop and mobile (Android). Integrated Service The integrated service implements the full feature set and incorporates adjustments after the experience with the MVP. Final Service The final version of the e-voting service, fully documented for developers and users, and proven in production conditions. Demonstrators, pilots, prototypes (1) Minimum Viable Product A viable demonstration of the designs and capabilities developed by Task 5.2, in a first integration with the mix-net service. Websites, patent fillings, videos etc. (1) Public Web Page and Blog A public webpage will be created and updated throughout the duration of the project.
