Gergely Tóth, Rump Session2 PETWorkshop 2004, Toronto, Canada, May 2004 General-purpose Anonymity Framework

Gergely Tóth, Rump Session3 PETWorkshop 2004, Toronto, Canada, May 2004 Extending the OSI Model ProblemProblem: current network layer architecture does not provide anonymity extend the existing OSI modelOur 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 Session4 PETWorkshop 2004, Toronto, Canada, May 2004 The New Architecture anonymity for messages Provides anonymity for messages by relaying them through intermediate nodes in order to break the end-to-end TCP link anonymous replies Enables anonymous replies thus provides bi-directional streams security Provides security (encryption, integrity protection, authentication, etc.) Application-level Application-level anonymity services (e.g. e-voting, e-payment)

Gergely Tóth, Rump Session5 PETWorkshop 2004, Toronto, Canada, May 2004 INDICARE INDIC ARE The INformed DIalogue about Consumer Acceptability of DRM Solutions in Europe

Gergely Tóth, Rump Session6 PETWorkshop 2004, Toronto, Canada, May 2004 Aim of INDICARE ProblemsProblems with user acceptance of DRM solutionProposed solution: bring together the different involved parties: users, solution providers, service providers, etc. informed dialogueStart an informed dialogue –discussions stimulated and informed by good quality input
