A method for processing data insertion and/or modification requests, which is implemented by an electronic processing device including a communication interface to receive the requests from a communication network. The method includes distributing data, within a plurality of buffers. Each buffer is associated with a record of a database. The association is made via a database record identifier present within the received insertion and/or modification requests. The data is inserted in the form of buffer records, including a value to be updated in and/or inserted into the database. The method also includes allocating data within the records of the database, from the buffers of the plurality of buffers. The allocation phase includes, for the buffer records that include an operational marking, executing, from a configuration file, a computer program specifically dedicated to the record and/or specifically dedicated to the data type of the value to be updated and/or inserted.

A transaction method for a user using a first and a second terminal and connected to a server via a first and a second communication channel, respectively. The first terminal sends a transaction amount to the server. The server establishes a verification code whose length depends on the transaction amount, then sends a request to the first terminal and the verification code to the second terminal. The user returns the request filled in with a copied code to the server using the first terminal. The server compares the verification code with the copied code and sends a transaction validation or invalidation message to the first terminal depending on the comparison.

In a method for cogenerating a shared cryptographic material implemented within a first electronic device, which is connected to a second electronic cogeneration device and to a third electronic cogeneration device, a shared encryption material (pkx) is determined, as a function of a set of cogeneration parameters ECG. The shared encryption material (pkx) is transmitted, and corresponding shared encryption materials (pky, pkz) are received from the other devices. A shared seed (mx) is computed as a function of the shared encryption materials (pkx, pky, pkz) and the set of cogeneration parameters ECG. A masked form (Ox) of said shared seed (mx) is transmitted, and masked forms (Oy, Oz) of corresponding shared seeds (my, mz) are received. A final seed (ad) is computed as a function of the masked forms (Ox, Oy, Oz) of the shared seeds (mx, my, mz) and the set of cogeneration parameters ECG.

The invention concerns a method for supplying data relating to a payment transaction to a communications terminal. A payment device capable of carrying out a payment transaction with said communications terminal, according to at least two distinct payment transaction modes, generates (E) a first signal relating to a first payment transaction mode, said first signal comprising at least one piece of information making it possible to set up the payment transaction via a first communications channel, and sends (E) said first signal, via said first communications terminal. Then, the payment device generates (E) at least one second signal relating to a second payment transaction mode, said second signal comprising at least one piece of information making it possible to set up the payment transaction via a second communications channel, and sends (E) the second signal, simultaneously with the sending of the first signal.
