A method of radio communication of a slave device with a master device, the method comprising steps of:

Method for radio communication of a slave device with a master device

The present invention relates to a device () such as a connected object comprising a first electronic circuit () comprising:

Device such as a connected object provided with means for checking the execution of a program executed by the device

Method for controlling commands suitable to be processed by a peripheral () comprising the following steps implemented by a control circuit () connected to a communication bus (), a command circuit () and the peripheral () also being connected to the communication bus (): granting or refusing authorization to the command circuit () to transmit a command signal of the peripheral via the bus (), detecting the possible transmission of the command signal for the peripheral by the command circuit via the bus (), implementing protection measures () when the control circuit detects that the command signal has been transmitted as the control circuit has not granted authorization, or that the command signal has not been transmitted as the control circuit has granted authorization.

Method for controlling commands suitable to be processed by a peripheral such as an actuator

The present invention concerns a method for securing data transmitted by a data source () of a connected object () against attacks affecting a control circuit () of the connected object (), the connected object () also comprising an electronic signature circuit () and a communication bus () connected to the control circuit (), connected to the electronic signature circuit () and connected to the source (), wherein the method comprises the following steps implemented by the electronic signature circuit ():

Method and system for securing data transmitted by a connected object against attacks affecting a control circuit of said object

Method for verifying data generated by an electronic device included in equipment, the electronic device including a computing unit, a one-time programmable memory and a volatile memory, the equipment including a rewritable non-volatile memory and a communication bus enabling the electronic device to store data in the rewritable non-volatile memory. The method includes: creating a secured channel by encryption between the equipment and a server; obtaining an authentication key from the server; loading data and a message authentication code from the rewritable non-volatile memory to the volatile memory, the message authentication code obtained by the electronic device from the authentication key and said data prior to the storage of said data and message authentication code in the rewritable non-volatile memory, the electronic device not having kept the authentication key following the obtaining of the message authentication code; verifying said data using the secret key and the message authentication code.
