Mode 2 - Server Certificate and self signed root Certificate in module form a chain
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
Section 12.2.1
, Step 1).
•
Certificate verification is activated for a data connection (HTTPS or SecureConnection).
The steps described below use the openssl environment (for installation see
http://
www.cygwin.com/
. The openssl documentation can be found here
http://www.openssl.org/
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.
