Abstract: A method for parameterising a device for performing banking operations in which biometric data of the holder of the device for performing banking operations are used to authenticate the user of the device. The present invention: activates a plurality of commands using identifiers of a standard relating to banking transactions available for effecting commands not predefined by the standard; creates, from an identifier of the standard relating to banking transactions available for effecting commands not predefined by the standard, in the device for performing banking operations, a container able to store reference biometric data of a user of the device for performing banking operations; and stores reference biometric data, using an identifier of the standard relating to banking transactions available for effecting commands not predefined by the standard, in the container of reference biometric data of the user of the device for performing banking operations.

Abstract: Challenge-response authentication process of a secure element (SE) in a micro controller unit (MCU) devoid of a random number generator. The process includes the following steps conducted by the micro controller unit (MCU): receipt of at least one random datum (T, IDX) generated randomly by the secure element (SE), generation of a challenge datum (Z) specific to the micro controller unit (MCU) from the received random datum (T, IDX), sending of the generated challenge datum (Z) to the secure element (SE), receipt of a response datum (R) generated by the secure element (SE) as a function of the challenge datum (Z), and determination of an authentication result as a function of the received response datum.

Abstract: The invention especially relates to a challenge-response authentication process (106) of a secure element (SE) in a micro controller unit (MCU) devoid of a random number generator, the process comprising the following steps conducted by the micro controller unit (MCU): receipt of at least one random datum (T, IDX) generated randomly by the secure element (SE), generation (206, 208, 210) of a challenge datum (Z) specific to the micro controller unit (MCU) from the received random datum (T, IDX), sending (212) of the generated challenge datum (Z) to the secure element (SE), receipt of a response datum (R) generated by the secure element (SE) as a function of the challenge datum (Z), determination (220) of an authentication result as a function of the received response datum.
