These switching means can also be distributed and dispersed on each element of the network.
- FIG. 3 illustrates an embodiment of means of switching in the form of an electronic circuit subsequently called the MUX multiplexing circuit.
- multiplexing is understood to mean transmitting data on two link channels selected from at least three channels, the data coming from the first of the two selected channels being transmitted to the second selected channel, and conversely, the data coming from the second selected channel being transmitted to the first selected channel.

- the transmitter then comprises a security module MS which has at least one secret identification key Kt in an inaccessible memory zone.
- the security module of the transmitter generates a pseudo-random number Rndl. From 'these two numbers Rndl and Kt, the DES algorithm implemented by the security module calculates a session key Kt •.
- the sender of the message to be certified requests the recipient, the central body 1 for example, to provide it with a second random number Rnd2.
- the DES algorithm is again applied to the session key Kt 'and to the second random number Rnd2 by the security module of the transmitter to calculate a certificate C.
- the data message is then sent to the recipient accompanied by the certificate C and the random number Rndl calculated by the card.
- the keys used in particular the secret identification key Kt and the session key Kt ', are not exchanged.
- Data message authentication is performed by recalculating a C certificate from the same data.
- the algorithm is therefore used a second time to authenticate the message by the recipient of the message.
- the recipient must therefore include a second security module, with the secret identification key Kt in memory.
- the second secure module can then calculate the session key Kt 'from the identification key Kt and the random number Rndl.
- the second secure module still has the random number Rnd2 which it previously supplied to the transmitter. From these two numbers Rnd2 and Kt *, the second security module again calculates a certificate C by applying the DES algorithm a second time.
- the recipient can authenticate the data message received.
- the multiplexing circuit MUX can thus identify the transmitters sending it messages, in particular the smart cards read by transcribers, and can also encrypt and decrypt the messages transmitted by each transmitter on the network.
- the multiplexing circuit MUX can also be responsible for encrypting data relating to the balance of value units and transfers of value units, that is to say the amounts transferred during gaming operations.
- the central computer sends a message intended for a slot machine 200.
- the MUX circuits of the switching devices 400, 401 and 402 receive the start of the message.
- the slot machines 201 and 202 can however exchange messages with their member transfer unit for value units 301 and 302, respectively.
- the circuit MUX of the device 400 places the channel 430 on standby towards the transfer member 300, the IT interface sending a wait signal.
- the circuit MUX of the device 400 translates the message, the microprocessor MP or the translators TR and TM translating the data of a protocol towards the protocol recognized by the electronics of the machine. Finally, the IM interface of the MUX circuit sends or repeats this message to the slot machine 200 via the link 420.
- the device 400 does not wait for the response from the machine 200 and prepares to accept a message from any channel 410, 420 or 430 to transmit this new message while the machine calculates its response. In this case, at the end of the first message, the device suppresses any waiting signal on its channels 410, 420 and 430. The device 400 can also wait for the response from the machine 200.
- the response message returns to the multiplexing MUX of the device 400, the circuit analyzes, translates and repeats the message to the central management unit 1 via the link channel 123 of the network.
- the multiplexing circuit MUX frees the channel 430 connected to the transfer unit 300. The slot machine can then resume the exchanges of data and d 'units of value with the transfer device 300.
- the slot machines 200, 201 and 202 inform the central organ of their state.
- a machine 200 can for example be in a non-operating state, a transmission error, or in a normal state.
- transfers of value units can be refused by the multiplexing circuit if the machine is in a non-operating state.
- the circuit MUX scans an indicator of the state of the slot machine. Depending on the state of the machine, it may or may not carry out the transfer unit value.
- the circuit MUX of the device 400 puts the channel 410 connected to the network on standby.
- the MUX circuit translates and repeats the transfer of value units message to the slot machine 200.
- the machine 200 checks the encryption of the message and records the amount transferred.
- the multiplexing circuit MUX waits for the response from the slot machine 200, translates it and directs it to the transfer member 300.
- the slot machine and the transfer member exchange a transfer message of units of value.
- the unit of value transfer member 300 checks the encryption of the message and delivers the winnings. If the transfer device is a data transcriber on a smart card, for example, it records the new balance of value units in the card's memory. After this operation, the transfer member 300 sends a conventional response if the operation has gone well and the multiplexing circuit MUX of the device 400 transmits it to the machine. Once the exchanges between the slot machine 200 and its transcriptionist 300 are completed, or preferably after each message transmitted, the waiting signal transmitted on the channel 410 by the IR interface of the multiplexing circuit MUX is deleted. It will be noted that a variant of switching means according to the invention can provide for the direct transmission of data between channel 430 of the transfer unit of value units 300 and channel 410 connected to the central computer 1 by the means of network link.
- An advantage of this variant is that the computer directly receives balance data supplied by the transfer member 300, or information on the player recorded on a chip card for example.
- a device according to the invention comprising a MUX multiplexing circuit with TM and TT translators can advantageously be used to simply translate the messages exchanged between a machine 200 and its unit for transferring value units 300, this sub-organ machine assembly 200, 300 not necessarily connected to a network.
- the device 400 then plays a simple interface role for translating the messages according to the planned protocol suitable for the recipient circuit.
- the switching means according to the invention are preferably arranged in an insulated housing which can be connected to the electronic links provided on existing machines.
- Another advantage of the invention is that it makes it possible to constitute a network with slot machines and transcriptionists using different message transmission protocols.
- the invention also makes it possible to secure data transfers, in particular transfers of value units corresponding to sums of money, by providing for the encryption of messages.
