Figure 6. Graph showing dependencies between IHE profiles (Grouping Dependencies): in (A), the diagram shows the dependencies among the profiles for the initial configuration of the Central Registry use case, as illustrated in (B), it is noteworthy that a security gap exists, as some profiles do not depend on XUA, while Figure 4 displays the dependencies between the profiles in the IHE IT Infrastructure Technical Framework, we can immediately detect that all the profiles depend on ATNA. IHE: Integrating the Healthcare Enterprise; XUA: cross-enterprise user assertion; IT: information technology; ATNA: Audit Trail and Node Authentication.
