This session discusses the extension of the OSI model to support anonymity, introduce new layers for different functions, and provide an implementation for general-purpose anonymity. Topics include application-level anonymity services and the new architecture for relaying messages through intermediate nodes.

  1. PETWorkshop 2004 — Rump Session Gergely Tóth Budapest University of Technology and Economics Department of Measurement and Information Systems SEARCH Laboratory Gergely Tóth, Rump Session 1 PETWorkshop 2004, Toronto, Canada, 26-28 May 2004

  2. General-purpose Anonymity Framework Gergely Tóth, Rump Session 2 PETWorkshop 2004, Toronto, Canada, 26-28 May 2004

  3. Extending the OSI Model • Problem: current network layer architecture does not provide anonymity • Our aim: extend the existing OSI model in order to support anonymity • introduce new layers for different functions • create an implementation (open source free software) Gergely Tóth, Rump Session 3 PETWorkshop 2004, Toronto, Canada, 26-28 May 2004

  4. Application-level anonymity services (e.g. e-voting, e-payment) Provides security (encryption, integrity protection, authentication, etc.) Enables anonymous replies thus provides bi-directional streams The New Architecture Provides anonymity for messages by relaying them through intermediate nodes in order to break the end-to-end TCP link Gergely Tóth, Rump Session 4 PETWorkshop 2004, Toronto, Canada, 26-28 May 2004

  5. INDICARE The INformed DIalogue about Consumer Acceptability of DRM Solutions in Europe Gergely Tóth, Rump Session 5 PETWorkshop 2004, Toronto, Canada, 26-28 May 2004

  6. Aim of INDICARE • Problems with user acceptance of DRM • Proposed solution: bring together the different involved parties: users, solution providers, service providers, etc. • Start an informed dialogue • discussions stimulated and informed by good quality input Gergely Tóth, Rump Session 6 PETWorkshop 2004, Toronto, Canada, 26-28 May 2004

  7. How to Benefit from INDICARE • Comprehensive and informative website • Electronic discussion forum • Newsletter • Five workshops • State of the art reports • Consumer survey • Publications for specifically targeted audiences “e-Payments for Digital Content” October 28, 2004 Budapest, Hungary together with HISEC Gergely Tóth, Rump Session 7 PETWorkshop 2004, Toronto, Canada, 26-28 May 2004
