Connecting a UPIC client to a server application
The requirement for encryption between an openUTM server application and a UPIC client is the availablitiy of cryptographic functions.
- In openUTM server applications on BS2000 systems the encryption functionality is always available.
In openUTM server applications on Unix, Linux and Windows systems the encryption functionality is only available after successful loading of an appropriate openSSL library.
As UPIC client an openUTM-Client for the UPIC carrier system must be used that supports the encryption functionality. For UPIC clients on BS2000 this is always the case. For UPIC clients on Unix, Linux and Windows systems the encryption functionality is only available after successfully loading an appropriate openSSL library.
Details on the use of the openSSL library in Unix, Linux and Windows systems can be found in the openUTM manual "Using UTM Applications on Unix, Linux and Windows Systems".
Connecting a terminal emulation to a server application (BS2000 systems only)
The encryption of VTSU is offered for connections between UTM applications on BS2000 systems and terminal emulations. VTSU-B uses a separate key management. The data and system access control mechanisms that come in conjunction with encryption are in effect, however. openUTM receives information from VTSU via the encryption level that was negotiated for the connection to the client.
The following requirements must be fulfilled:
One requirement is the use of VTSU-B and the VTSU-SEC selectable unit. Which of the current versions you must use is described in the release notes for openUTM. You can consult the Release Notice for VTSU-SEC to determine which VTSU parameters must be set.
A terminal emulation must be in use on the client that supports the encryption functions.
These communication partners are called VTSU partners in the following.
