Message multiplexing method, device and corresponding program
View Patent ↗A method is provided for multiplexing messages exchanged between a payment terminal and a communication terminal via a connection between the payment terminal and the communication terminal using the iPod Accessory Protocol, iAP. The method includes: an initialization step of initializing an external communication interface with the communication terminal, a first transmission step of transmitting, to the communication terminal, a request for creation of remote virtual channels via the external communication interface; a creation step of creating, within the payment terminal, local virtual channels corresponding to the remote virtual channels; and a second transmission step of transmitting data frames associated with the local virtual channels via the external communication interface.
1. A method for multiplexing messages exchanged between a payment terminal and a communications terminal through a connection between said payment terminal and said communications terminal using the iAP protocol, wherein the method comprises:
a step of initializing an external communications interface with said communications terminal;
a first step of transmission of a request for creating remote virtual channels, from said payment terminal to said communications terminal through said external communications interface;
a step of creating, within said payment terminal, local virtual channels corresponding to said remote virtual channels; and
a second step of transmission of associated data frames to said local virtual channels by using said external communications interface.
2. The method according to claim 1 , wherein said external communications interface is an RS232 interface.
3. The method according to claim 1 , wherein the method further comprises, prior to said step of initializing a communications interface, a step of authenticating said payment terminal in relation to said communications terminal comprising:
a step of obtaining an authentication certificate; and
a step of verifying the authorization of the payment terminal to be paired with said communications terminal using said authentication certificate.
4. The method according to claim 1 , wherein said second step of transmission of associated data frames to said local virtual channels comprises:
a step of verifying a presence, within said virtual channels, of an FLV frame intended for the communications terminal;
and when one of the channels comprises such a frame:
a step of encapsulating this FLV frame in an iAP message.
5. The method according to claim 1 , wherein said virtual channels belong to the group consisting of:
a virtual “transaction” channel for exchanging data on banking transactions;
a virtual “configuration” channel for exchanging pieces of service information;
a virtual “SSL” channel for encrypting data transmission between said payment terminal and said communications terminal;
a virtual “printer” channel for transmitting printing data;
a virtual “barcode” channel for managing the reading of the barcodes.
6. The method according to claim 1 , wherein a virtual channel is created in the form of a queue, said queue being configured to enable reception, recording and erasure of FLV frames intended for said virtual channel.
7. A device for multiplexing messages exchanged between a payment terminal and a communications terminal by means of a connection between said payment terminal and said communications terminal using the iAP protocol, wherein the device comprises:
means for initializing an external communications interface with said communications terminal;
first means for transmission of a request for creating remote virtual channels, from said payment terminal to said communications terminal through said external communications interface;
means for creating, within said payment terminal, local virtual channels corresponding to said remote virtual channels; and
second means for transmission of associated data frames to said local virtual channels through said external communications interface.
8. A non-transmissible information carrier storage device comprising a computer program product stored thereon and comprising program code instructions for execution of a method for multiplexing messages exchanged between a payment terminal and a communications terminal through a connection between said payment terminal and said communications terminal using the iAP protocol, when the instructions are executed on a computer, wherein the method comprises:
a step of initializing an external communications interface with said communications terminal;
a first step of transmission of a request for creating remote virtual channels, from said payment terminal to said communications terminal through said external communications interface;
a step of creating, within said payment terminal, local virtual channels corresponding to said remote virtual channels; and
a second step of transmission of associated data frames to said local virtual channels by using said external communications interface.
