Abstract: A secure method for establishing communications to provision modules in an industrial control system generates a certificate signing request to obtain a signed security certificate. A mobile device is located proximate to the module with the certificate signing request, and the mobile device has previously established itself as a secure communication interface on the network. The mobile device establishes a first connection between the module and the mobile device via a short-range protocol and a s second connection between the mobile device and a signing server via a network. The mobile device retrieves the certificate signing request via the first connection and transmits the certificate signing request to the signing server via the second connection. Because the mobile device has previously established itself as a secure interface, the transmission of the certificate signing request to the signing server may be made via a secure connection.
