    Abstract: A method and a payment terminal enable verification of the authenticity of a payment terminal. More particularly, a method is provided for processing a piece of initial data, carried out within the payment terminal, the payment terminal being configured to authorize a verification of its authenticity by using the piece of initial data. The method includes: obtaining at least one piece of information external to the payment terminal, called a piece of initial data; cryptographic processing of the piece of initial data, delivering a piece of processed data; visual and/or sound rendering of the piece of processed data.

    Abstract: A method is provided for authenticating a user's communications terminal with an authentication server connected to a gateway terminal by using a communications network. The method includes: obtaining a piece of data representing an identity of the user from the gateway terminal; configuring, by the authentication server, a data transmission link between the authentication server and the terminal, using a predefined data transmission interface of the gateway terminal and as a function of the piece of data representing the identity of the user; transmitting, by the authentication server, to the terminal, a piece of encrypted data for checking authentication, using the data transmission link; receiving, by the authentication user, coming from the terminal, a piece of encrypted data for counter-checking authentication; issuing an assertion of authentication of the user when the piece of data for the counter-checking of authentication corresponds to the piece of data for checking authentication.

    Abstract: It is proposed a device and method for finding nilcatenations, and proposes nilcatenation detection techniques, which can be applied to blockchains, and even constitute a proof of useful work, as the periodic removal of nilcatenations keeps a ledger size as small as possible. Banks and blockchains need to keep track of an ever-increasing list of transactions between the accounts owned by their users. However, as time goes by, many of these transactions can be safely “forgotten”, in the sense that purging a set of transactions that compensate each other does not impact the network's semantic meaning i.e. the vector Bt of amounts representing the balances of users at a given point in time t. Nilcatenation refers to a collection of past transaction vectors having no effect on Bt. Removing these transactions yields a smaller, but equivalent set of transactions.

    Abstract: The invention relates to a method for transmitting data from a first terminal, called a sender terminal (TermE), to a second terminal, called a receiver terminal (TermR), the method being characterized in that it comprises: a step (100) for obtaining a piece of current time data (DTC); a step (110) for determining a piece of transmission time data (DTC) as a function of the piece of current time data (DTC) and at least one predetermined parameter; a step (120) for obtaining a piece of data to be encrypted (DaCh) from at least one piece of data to be transmitted (DaTr) and from at least one piece of current time data (DTC); a step (130) for encrypting, by means of an encryption key (KeyC), said preliminarily obtained piece of data to be encrypted (DaCh), this step delivering a piece of encrypted data (DCh); a step for transmitting said piece of encrypted data (DCh) as a function of said piece of transmission time data (DTT).
