A system for unlocking and/or opening an openable member of a motor vehicle comprises a control unit, transmitter/receiver means connected to said control unit, and a transponder worn or carried by a user. The transmitter/receiver means of the vehicle comprise at least one antenna situated on the openable member or in the vicinity thereof, said transmitter/receiver means entering into dialogue with the transponder only when it is situated in the immediate vicinity of said antenna. The control unit causing the openable member to be unlocked and/or opened when the transponder is presented in a predetermined sequence to the antenna(s) of the transmitter/receiver means of the vehicle.

Proprietary cryptography is a term used to describe custom encryption
techniques that are kept secret by its designers to add additional security. It is questionable if such an approach increases the cryptographic strength of the underlying mathematical algorithms. The security of proprietary encryption techniques relies entirely on the competence of the semi - conductor companies, which keep the technical description strictly confidential after designing. It
is difficult to give a public and independent security assessment of the
cryptography, without having access to the detailed information of the design.
The first part of this dissertation is dedicated to an introduction of the
general field of computer security and cryptography. It includes an extensive description of the theoretical background that refers to related literature and gives a summary of well - known cryptographic at
tack techniques. Additionally, a broad summary of related scientific research on proprietary cryptography is given. Finally, the technical part of this doctoral dissertation presents serious weaknesses in widely deployed proprietary cryptosystems, which are still actively used by billions of consumers in their daily lives.

A door handle (82) for a vehicle which can miniaturize a transmitter provided on the vehicle and reduce a cost of the system is provided. The door handle (82) includes a handle body (87, 88) which is mounted on an outer face (84) of a door (80) of the vehicle. A least a transmitting antenna (11) of a transmitter (11, 14) which transmits a radio signal toward outside of the vehicle is integrated with the handle body (87, 88). A smart entry system for a vehicle using the door handle (82) is also provided.

A remote control system for locking and unlocking a passenger space in a motor vehicle has an on-board unit that includes an emitter of signals SE of a first type and receiver of signals SP of a second type. There also is a portable device that has a receiver of first type signals SE and an emitter of second type signals SP. The apparatus also detects that the portable device has been forgotten inside the passenger space by determining the relative position of the portable device in relation to the interior of the passenger space. The apparatus for determining the position of the portable device in relation to the interior of the passenger space is integrated into the portable device with the portable device emitter of the second type signal Spforgotten in the event of detection of the portable device having been forgotten inside the passenger space.

In a method for detecting a portable transponder (6), locked inside a vehicle, for a key-less access system for vehicles, in which method the position of the transponder is detected and possibly a signal is triggered via a question/answer dialogue triggered during the locking, the dialogue is triggered when a locking command is issued and the locking is only carried out when the transponder is detected outside the vehicle (1).

Method for detecting portable transmitter left inside vehicle

A keyless entry system for locking and unlocking vehicle doors, and for opening the trunk is described. This system utilizes a small (ordinary credit-card size) card transponder with a built-in personal identification code that can be carried in a pocket or a briefcase and the user does not have to take it out for use because the signal transmission is effected by inductive coupling between the card and loop antennas built into the door mirror housing and rear bumper. By touching a switch provided near the trunk keyhole, the user can open the door or trunk as if there were no locks. For anti-theft security and reliability, the system incorporates a twin-loop antenna that generates a rotating magnetic field, and a detection system to prevent the card transponder from being left inside the vehicle. This system has been installed in the luxury classes of Nissan models in the Japanese market. >
