Authentication and Encryption in the Snow Disease Surveillance Network

The paper presents how authentication and encryption is implemented in the Snow disease surveillance network. Requirements for the authentication mechanism were collected from General Practitioners (GPs). The identity of each Snow user is preserved across health institutions allowing GPs to move freely between health institutions and use the system independent of location. This ability is combined with close to zero user account administration within the participating institutions. The system provides global user certificate revocation and end-to-end encryption.
