12.1.1

Create a Secure Data Transfer Environment Step by Step

The following steps describe the configuration:
• The certificate exists within the module (see
• Certificate verification is activated for a data connection (HTTPS or SecureConnection).
The steps described below use the cygwin + openssl environment (for installation see
www.cygwin.com/. The openssl documentation can be found here
docs/apps/openssl.html)
A CA Root certificate is generated. This certificate can be placed on the HTTPS-Server.
Another possibility is to use the private key of the certificate in order to sign thereby a server
certificate. Both certificates form then a chain, which can be examined by the ME. A step-by-
step description for the latter scenario can be found below.
