Definitions

• a portable box intended to allow a player to perform one or more tests of games of chance, success or failure in said tests conditioning a score or a level of gain according to predetermined rules of the game .
• This box then also constitutes the transaction element for the payment of the gain and includes all the elements necessary for the verification thereof.
• each autonomous unit can be used only once. This naturally poses an economic and ecological problem due to this unit use combined with an estimated distribution of the order of several tens of millions of units per month.
• the portable object which is intended to contain both the digital game data defining the game itself, as well as the result information allowing the player to validate this result so as to touch possibly his gain.
• the portable object here constitutes the transaction element while the box is only used by the player for playing.
• the device according to the invention generally comprises several boxes and several portable objects. Also, when the authentication of the set of game data of one of the portable objects has been verified and that said set has been stored in the working memory of one of the boxes, any subsequent operation is advantageously prohibited. by any of the boxes, from the set of game data for this portable object.
• any validation station knows this encryption-game key since it is common to all the elements of the device. This being so, when the encryption-result key is not known in advance by the validation station, provision is made for storing in the portable object cooperating with the box, key information associated so one-to-one with said encryption-result key, the validation station then having access to said encryption-result key by reading said key information stored in the portable object.
• the processing unit is capable, during cooperation between the communication interface-box and the first communication interface of the object, of verifying the authentication of the set of game data stored in the object and to store said assembly in the working memory so as to allow the progress of the game at the level of the housing.
• the processing unit of the box is also capable of encrypting result information dependent on said game, using the encryption-result key, and of communicating this encrypted result information to the communication-box interface for the purposes of its storage in the result memory of the object.
• the validation station includes means able to determine said encryption-result key and processing-station means able to read the encrypted result information via the communication interface.
• the station processing means may include station decryption means capable of decrypting the encrypted result information for the purpose of its determination.
• the processing unit of the box is able to also communicate the unencrypted result information to the communication-box interface for the purpose of its storage in the result memory of the object.
• the station-processing means are then further able to read the unencrypted result information via the station-communication interface. They then include station-encryption means capable of encrypting said unencrypted result information using the encryption-result key, as well as comparison means for comparing the recalculated encrypted result information with the information. result result stored in the result memory of the portable object. This comparison thus makes it possible to verify the result information.

• the device according to the invention comprises several autonomous electronic boxes BT, several portable objects OB and several validation stations ST.
• the game memory MJ for example a read only memory, is intended to receive a set of digital game data, or game software, representative of a particular type of game.
• the ESC interface includes means of cooperation with a homologous interface ESB of the box BT (FIG. 2) and a homologous interface ESS of the station ST (FIG. 3). These cooperation means may consist of a mechanical connector or alternatively of capacitive / inductive, or optical coupling means.
• the hardware electronic structure of the portable box BT is articulated around a processing unit UT, such as a microprocessor or a microcontroller.
• This processing unit UT is connected via a bus to a working memory MT, accessible by writing and reading, for example a random access memory (RAM), to a program memory MM as well as to a standard memory of key MC which is a protected memory which can be a part of the memory MM-
• the unit of processing is also connected to a liquid crystal display screen AF as well as to a keyboard C1 comprising for example keys for controlling movements in two orthogonal directions.
• the processing unit is connected to a communication interface-ESB box capable of cooperating with the communication interface ESC, and which can for example include a mechanical connector disposed in a housing in which the connector of the portable object.
• the ESB interface also includes serial / parallel conversion means connected to the internal bus of the box. All of the means of this box are supplied by autonomous supply means AL such as batteries. All or part of the components of this case can be made in the form of an Asia.
• each validation station ST comprises a processing block articulated around a processor PR connected to an input / output interface ESS capable of cooperating with the input / output interface ESC of the portable object. Furthermore, the station is connected via an appropriate link, to a central file TB containing information necessary, as will be seen in more detail below, for the verification of the result information contained in the portable object.
• the station's PR processor software embeds the various functional means necessary for its operation (encryption, decryption, comparison, reading, etc.).
• the digital game data set JE On a manufacturing site, the digital game data set JE, forming the game application software, is processed by processing means comprising a well-known authentication certificate calculation algorithm of the SHA (Secure Hash Algorithm) type. of the skilled person. The latter may however, for more details, refer to publication 180-1 of May 31, 1994 issued by the FIPS (Federal Information Processing Standards).
• SHA Secure Hash Algorithm
• calculation means determine a CTF audit certificate from logical functions operating on the bits of the digital game data (step 1).
• the authentication certificate comprises for example 120 bits.
• the authentication verification of the JE game software can be done either "on the fly", or when all of the software has been transferred in the working memory MT, this latter solution requiring a greater capacity of random access memory.
• step 21 After storing Tir-formation of encrypted result IFRc in the result memory of the object, it is checked whether this alteration has taken place (step 21). If so, allow the storage in the result memory MR ' and if not, this storage is prohibited.
• This ICR information can be, for example, the encryption-result key proper or else an identifier of the box which is associated in a one-to-one fashion with the box and consequently the encryption-box key Kf which has been stored.
