<H3>Description</H3> <p>The purpose of the ATNAAuthentication test is for Secure Nodes (ATNA or Basic Security) to exchange certificates and then perform communication over the established connection. This implies DICOM, HL7 or other communication over the established connection.</p>  <p>Evaluation will require the both applications to show log files or other evidence that certificates were successfully exchanged and an IHE transaction occurred. The transaction will be a subset of an Integration Profile.</p>  <H3>Evaluation</H3> <p>Connectathon monitor will examine log files of both applications for evidence of certificate exchange. Systems should also be able to demonstrate that some transaction was completed (Patient ADT, MWL worklist query).</p>  <p>The systems under test need to demonstrate only one type of transaction is operational using the TLS communication.</p>
