Increasingly, national and international governments have a strong mandate to develop national e-health systems to enable delivery of much-needed healthcare services.  Research is, therefore, needed into appropriate security and reliance structures for the development of health information systems which must be compliant with governmental and alike obligations.  The protection of e-health information security is critical to the successful implementation of any e-health initiative.  To address this, this paper proposes a security architecture for index-based e-health environments, according to the broad outline of Australia’s National E-health Strategy and National E-health Transition Authority (NEHTA)’s Connectivity Architecture.  This proposal, however, could be equally applied to any distributed, index-based health information system involving referencing to disparate health information systems.  The practicality of the proposed security architecture is supported through an experimental demonstration. This successful prototype completion demonstrates the comprehensibility of the proposed architecture, and the clarity and feasibility of system specifications, in enabling ready development of such a system.  This test vehicle has also indicated a number of parameters that need to be considered in any national indexed-based e-health system design with reasonable levels of system security.  This paper has identified the need for evaluation of the levels of education, training, and expertise required to create such a system.
