Technical requirements for the handover interfaces for the execution of telecommunications surveillance

 PTSS sends an email with the interception order. The order is a deactivation order using the UPDATERequest action in the XML (see details in section 4.3.3.1.5). The body and the attachments of the email are signed and encrypted with the OpenPGP keys.

 CSP confirms the reception of the secure email order by sending back the received email body but without the attachments. The email's original subject is prefixed with the Re:

denoting a response. No signing and encryption is necessary for this step as the original email was already signed and encrypted.

 Once the interception order has been deactivated the CSP sends back the filled-in order form as a signed and encrypted attachement. The CSP shall use the UPDATEResponse action in the XML file (see details in section 4.3.3.1.5).

 PTSS will acknowledge the reception of the filled in order form to the CSP by sending a simple email response with no content. No signing and encryption is necessary for this step.
