Yes..I already went through the links but didn't understand what to do because I am new to DCM4CHE and DICOM. Just today I learned what they are. Can you please elaborate on what to do.

IHE ATNA includes 2 independent requirements:
- using TLS for all network protocols (https, dicom-tls, hl7-tls)
- sending/receiving XML Audit Records via syslog-tls and/or syslog-udp

https://github.com/dcm4che/dcm4che/tree/master/dcm4che-audit/src/main/java/org/dcm4che3/audit provides classes for creation of the XML Audit records

syslog-tls and/or syslog-udp

dicom-tls and hl7-tls is supported by

Hii gunterze,

I had a look at the code, I understood how are the XML Audit Records being created and how they are being sent/received.
 
Now to implement ATNA, can you explain me what should be the input and the stepwise attainment of the goal. This would be very helpful to me. And how is the class createMessage in the creation of the XML Audit records getting the input?

Can you tell me, how to manually create a DeviceExtension ???I know we have a class DeviceExtension, but in that, the setDevice(Device device) is a private method...and I want to access it in another project

There are lot of samples for subclassing DeviceExtension in dcm4che and dcm4chee-arc-light. Method setDevice is not intended to be used externally! It's only purpose is to update the relation on adding/removing a Device Extension by Device::addDeviceExtension / Device::removeDeviceExtension

Everything is working fine..but when I am sending the XML to a Syslog server, I am facing the below error

XML string expected but the following exception occurred on parsing expected XML data: Data at the root level is invalid. Line 1, position 1.
It means that the hidden character is BOM. How to remove this?
In the AuditLogger class, there is a field called BOM, but didn't understand why it is enabled to true and the purpose of it??

Seems your syslog receiver is not compliant with RFC 5424 The Syslog Protocol :
If a syslog application encodes MSG in UTF-8, the string MUST start with the Unicode byte order mask (BOM)

Anyway, you can control inclusion the BOM by AuditLogger property "includeBOM".

Here according to your code, there will be a sending device and a receiving device ryt. I am able to set the receiving device, but when I want to set the sending device, the method setDevice() in the AuditLogger class is made default. Now how can I access it?. I checked if that method is being called in some public method. But didn't find any clue.

I am using an iwatt server and configured it to a secured tls connection. When i configure the protocol in the atna code to use Syslog_tls, i am getting a message that the audit message is sent but couldn't see the message in the server.
Can you help me with this?
