Abstract

The keypad disclosed has key values which are not predefined. Definition of these keys is carried out at randum and possibly in a conventional manner. Application is found in all fields where a (secret) code gives confidential access, as in the case of banking operations in particular. In such applications, the keypads are normally, but not exclusively, numeric.

Description

Clavier a initialisation aleatoire
La presente invention concerne les daviers, materiels ou affichés sur un ecran. au moyen desquels l'homme communique avec une machine et elle a pour objet d amelinrer la sécurite de cette communication.Random initialization keyboard
The present invention relates to davits, equipment or displayed on a screen. by means of which humans communicate with a machine and its purpose is to improve the security of this communication.

Dans certaines applications, bancaires notamment, mais aussi celles Lieues a un acces hahitation. véhicule. autres un usager est amene .1 composer un code pour authentifier cet acces. Au moyen des claviers connus. la présence d un tiers rend souvent cette operation peu sure. In some applications, banking in particular, but also those Lieues has a hahitation access. vehicle. others a user is brought .1 dial a code to authenticate this access. By means of known keyboards. the presence of a third party often makes this operation unsafe.

Lors de la composition d'un code, pour les claviers dont la valeur des touches est fixée definitivement a la construction du clavier. les mouvements des doigts permettent a un observateur. me me bien intentionné. de retrouver le code composé. Il est donc du plus haut intérét d'avoir des claviers dont seul l'utilisateur connaisse la valeur des louches.  When composing a code, for keyboards whose value of the keys is definitively fixed to the construction of the keyboard. finger movements allow an observer. me well-intentioned. to find the code composed. It is therefore of the highest interest to have keyboards of which only the user knows the value of ladles.

C est ce que permet un clavier realise suivant l'invention. This is what a keyboard made according to the invention allows.

Il y a déjà des claviers dont les touches peuvent prendre plusieurs valeurs. et ou cette valeur est affichée par ailleurs. Dans ces claviers la valeur de touches va s'afficher ou bien sur la touche elle me me ou bten dans une fenêtre a coté de chacune des touche, ou bien dans une seule fenétre un peu plus grande représentant le clavier Ce qui caracterise notre invention c est que cette valeur est définie de facon aleatoire. au moins dans la phase d'authentification. There are already keyboards whose keys can take multiple values. and where this value is displayed elsewhere. In these keyboards the value of keys will be displayed either on the key it me or bten in a window next to each of the keys, or in a single window a little larger representing the keyboard What characterizes our invention c is that this value is randomly defined. at least in the authentication phase.

Le prucessus automatique de définition de la valeur va utiliser un generateur de nombres pseudoaleatoires. Ce generateur peul être local. The automatic process of defining the value will use a pseudo-random number generator. This generator can be local.

Lorsque ces claviers sont relies a un appareil central ce génerateur peut aussi étre central.When these keyboards are connected to a central device, this generator can also be central.

On peut aussi avoir un tel clavier laissant a l'usager. qui le prefererait, la possibilité de travailler dès le départ avec un clavier standard. We can also have such a keyboard leaving the user. who would prefer it, the possibility of working from the start with a standard keyboard.

Les divers caractéristiques et avantages de l'invention ressortiront de la description qui va suivre. de quelques unes de ses formes possibles de realisation. etant bien entendu qu'il s'agit uniquement d'exemples non limitatifs. toutes autres dispositions pouvant être adoptees sans sortir du cadre de l'invention. The various characteristics and advantages of the invention will emerge from the description which follows. of some of its possible forms of realization. it being understood that these are only nonlimiting examples. all other provisions which can be adopted without departing from the scope of the invention.

Au cours de cette description on se réfere au dessin ci-joint sur lequel
La Fig. 1 represente un clavier (numerique) avec son initialisation habituelle.During this description, reference is made to the attached drawing on which
Fig. 1 represents a keyboard (numeric) with its usual initialization.

La Fig. 2 represente un clavier Fnumerique) non initialise.
la Fig. 3 represente le même clavier apres initialisation aléatoire. Fig. 2 represents a digital keyboard) not initialized.
Fig. 3 represents the same keyboard after random initialization.

La Fig. 4 represente le clavier I, le microprocesseur 2, le systeme central 4, l'initialisateur 3. Fig. 4 represents the keyboard I, the microprocessor 2, the central system 4, the initializer 3.

Les differentes parties d un clavier sont suffisamment connues pour que nous ne les @re@définissions pas ici. The different parts of a keyboard are sufficiently well known that we will not define them here.

Les touches n'ont pas toutes ici la méme forme @celle numerotee 0 sur la figure 1)
cette même touche nest pas valorisee sur la figure 3.The keys do not all have the same form here @ that numbered 0 in Figure 1)
this same key is not valued in FIG. 3.

Le clavier figure 1 est relie physiquement au microprocesseur n lui même relie au systeme central 4 et ce de la me me façon que le systeme habituel. Le microprocesseur est d autre part relie a la commande dinitialisation 3. le systeme recevant la carte par exemple.
e microprocesseur a deux objets:
1- Iniiialiser les touches du clavier.The keyboard in Figure 1 is physically connected to the microprocessor n itself connects to the central system 4 and this in the same way as the usual system. The microprocessor is also connected to the initialization command 3. the system receiving the card for example.
The microprocessor has two objects:
1- Initialize the keyboard keys.

7- Transmettre au systéme central les differents codes correspondant a la pression des différentes touches de 0 a 9. 7- Transmit to the central system the different codes corresponding to the pressure of the different keys from 0 to 9.

A l'introduction de la carte le clavier est dans l'état de la figure 1. nombre de microsecondes de Ihorloge du microprocesseur par exemple. va alors Anitialiser le génerateur de nombres aleatoires de ce microprocesseur @ou programme sur ce microprocesseur@. Les valeurs des touches vont safficher sur celles-ci @ou à coté de celles-ci) et vont prendre, par exemple. l"etat de celles de la figure ,1.  When the card is inserted, the keyboard is in the state of FIG. 1. number of microseconds of the clock of the microprocessor for example. will then initialize the random number generator of this microprocessor @ or program on this microprocessor @. The values of the keys will be displayed on these @ or next to these) and will take, for example. the state of those in the figure, 1.

Lors de la composition du code secret, les codes des touches pressees sont transmis au microprocesseur qui les transcode en ceux de la valeur affichée sur les touches pour les transmettre au systeme central.  When entering the secret code, the codes of the pressed keys are transmitted to the microprocessor which transcodes them into those of the value displayed on the keys to transmit them to the central system.
