Abstract: A method for authenticating data, implemented during a payment transaction between a merchant's communications terminal and a user device of the type including authentication by the communications terminal of at least one message generated by the user device, by using near field communications wireless data. The method includes the following acts by the user's device: obtaining an authentication code from the message, a piece of random data and a hash function; obtaining a first signature component from the message, the random piece of data, a public key of the communications terminal, a first private key of the user device and the authentication code; obtaining a second signature component from the message, the random piece of data, the public key of the communications terminal, a second private key of the user device and the authentication code; and transmitting the authentication code and of the two signature components to the communications terminal.

Abstract: A method of encryption of a message implemented by an electronic encryption device. The method includes: obtaining a current message; obtaining a current encryption key; determining, from a plurality of variants a basic encryption protocol, of a current variant of the encryption protocol; encrypting, by using the current variant and the encryption key, the message to be encrypted, delivering an encrypted message; and transmitting the encrypted key.

Abstract: A method for authenticating at least one piece of data during a payment transaction taking place between a merchant's communications terminal and a user device of the type including transmission, by the communications terminal, of at least one piece of data to be signed, to the user device by using a near field communications wireless data link. The method includes: obtaining the piece of data to be signed; obtaining an identifier of the communications terminal; signing, within a secured processing unit of the communications terminal, by using a key of the communications terminal, the piece of data to be signed and the identifier of the communications terminal, delivering signed pieces of data; transmission of the signed pieces of data to the user device; and reception, from the user device, of a piece of encrypted data establishing the authentication of the signed pieces of data.

Abstract: A method is provided for managing a display of a view of an application, executed on a non-secured processor of an electronic data entry device that furthermore includes a secured processor. The application delivers at least one current view having a set of pixels to be displayed on a screen of the device. The managing is implemented under the control of the secured processor and includes: analysis of the current view, delivering at least one piece of data representing a presence of at least one suspect pattern; and, when a presence of a suspect pattern is detected within the current view, implementing by the secured processor at least one protection measure.
