Example

[0059] - The fourth exemplary embodiment corresponds to the case where n≠0 and m≠0

[0060] - In a second step, when the smartphone SP in scan mode receives the data frame Td and therefore the identification data element RPAi, it calculates the encrypted check code R'i on the one hand. This check operation takes place in the secure area 107 by means of the same encryption function Fc as present in the vehicle Vi; the latter has been stored in the secure area 107 by means of the cardlet software element containing this encryption function Fc. The formula for R'i is as follows:

[0061] R'i=Fc(Vidi,M,N)

[0062] The data element M has been received when the RPAi is sent, the data element N is the data element obtained by the smartphone SP.

[0063] If the smartphone SP receives a data frame TD' transmitted by a vehicle Vi' other than the vehicle it has been authorized to use, the first cipher Vidi used to calculate the encrypted check code R'i will give the result (R' i=Fc(Vi...

Abstract

The invention relates to a method for automatic recognition between a mobile electronic device (SP) and a motor vehicle (Vi) equipped with an electronic communication module (120), said mobile electronic device (SP) and the electronic module (120) of the vehicle (Vi) being capable of operating according to the BLE protocol, the mobile electronic device (SP) being in a 'scanning' mode and the electronic communication module (120) of the vehicle (Vi) being in an 'advertising' mode characterised in that it comprises various steps consisting of: - in the electronic module (120) of the vehicle (Vi), obtaining identification data (RPAi) of the vehicle (Vi); - transmitting at least one data frame (Td) comprising the identification data (RPAi) of the vehicle (Vi), from the electronic module (120) of the vehicle (Vi) to the mobile electronic device (SP); - receiving the at least one data frame (Td) containing the identification data (RPAi) of the vehicle (Vi), in the mobile electronic device (SP) set in 'scanning' mode; - checking, in the mobile electronic device (SP), that the transmitted identification data (RPAi) is valid, then transmitting a connection request (110) from the mobile electronic device (SP) to the electronic module (120) of the vehicle (Vi).

Description

technical field [0001] The present invention relates to a method for automatic identification between an electronic mobile communication device and an electronic module of a motor vehicle, said mobile communication device and said electronic module of a motor vehicle being able to operate according to Bluetooth Smart or Bluetooth Low Energy (BLE) Protocol exchange signals. The technical field of the invention is the access to motor vehicles by means of not using a mechanical key (KEY). [0002] In the context of this document, the expression "electronic mobile communication device" is taken to mean any electronic device enabling a person to access data and information via at least one telecommunication network, for example of the GSM or Bluetooth type. Thus, the term "mobile communication device" includes cell phones, more specifically of the smartphone type, portable computers, tablet computers, personal digital assistants (PDAs) and the like. In this document, by way of no...
