Figure 56: Mode 2 - Server Certificate and self signed root Certificate in module form a chain
11.1.1
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
. The openssl documentation can be found here
)
A CA Root certificate is generated. This certificate can be placed on the HTTPS-Server. Anoth-
er possibility is to use the private key of the certificate in order to sign thereby a server certifi-
cate. 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.
