Paper Abstract:
|
Numerous European countries are currently engaging in e-government initiatives that often comprise
issuing digital identification cards to citizens. As most of these cards base access control solely on the
identity of the cardholder, the issue of privacy arises. We present a scenario where it is desirable that
citizens can access services while remaining fully anonymous. We consider the requirements for an
anonymous access from the perspective of both government and citizens. Starting from the idea of
mapping the problem of anonymous access to a group membership problem we present a credentialbased
solution in which digital credentials are used to extend the digital identity of the citizen. We
consider the infrastructural components that an administrative body must introduce when using
credentials for service access. We finally propose cryptographic means for the implementation of such a
system with low-cost cryptographic credentials and smart cards. The implications of the smart card as a
computationally restricted environment are discussed and an outlook on future research on credentials in
e-government use is given. |
