Abstract

A method and device for securing electronic data exchange between an industrial programmable device implementing industrial process control and a portable programmable device, said portable programmable device being adapted to be operated by a user and to exchange electronic data with said industrial programmable device via a first communication protocol, each of said industrial programmable device and portable programmable device comprising a communication module enabling said first communication protocol. The method comprises, on each device, 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 and a second user identifier read on the portable programmable device are identical, and in case of negative verification, disabling the communication module of the industrial programmable device and/or the portable programmable device.
