| 摘要 |
The invention concerns a method and device for securing electronic data exchange between an industrial programmable device (2) implementing industrial process control and a portable programmable device (4), said portable programmable device (4) being adapted to be operated by a user and to exchange electronic data with said industrial programmable device (2) via a first communication protocol, each of said industrial programmable device and portable programmable device comprising a communication module (6, 30) enabling said first communication protocol. The method comprises, on each of the devices (2, 4), reading a user identifier, disabling the communication modules of said devices if the user identifier is not recognized in a locally memorized set of authorized users, and verifying whether a first user identifier read on the industrial programmable device (2) and a second user identifier read on the portable programmable device (4) are identical, and in case of negative verification, disabling the communication module (6) of the industrial programmable device (2) and/or disabling the communication module (30) of the portable programmable device (4). |
