s

Strictly confidential / Released

 

-keyfile ./democa/private/cakey.der -certfile ./democa/cacert.der

6.Export private key from server certificate

-The private key is needed for the (HTTPS or Secure Connection)server configuration.

-execute command

>java -jar getprivatekey.jar -alias server

-keystore customer.ks -storepass keystorepass -keypass keypass -keyfile server_privkey.der

Result:

-You have a keystore for the configuration of the Java Security of the module

-You have a signed server certificate (files ““server.pem” or “server.der”)

-You have a private key file for your server configuration

11.2Execution Control

The Java environment of the TC65 module has two modes.

unsecured mode:

•The device starts all java applications (MIDlets).

secured mode

•The customer can activate the secured mode of the device. For this the customer sends a root certificate (x.509 certificate) to the device (over an AT-Interface). The device changes from “unsecured mode” to the “secured mode”. From this time the module will only start java applications with a valid signature. In addition, the device will only accept special commands from the customer if they are marked with a signature. The device examines each command with the public key of the customer root certificate

The secured mode is activated by a special AT-command.

Siemens supplies modules with unsecured mode as the default configuration.
