    Abstract: An authentication method is performed between a first party and a second party. The method includes: i) determining a challenge; ii) sending the challenge to the second party; receiving a response from the second party including a second cryptogram; computing a first cryptogram using the challenge and the key of the first party; determining if the first cryptogram matches the second cryptogram received from the second party. If the first cryptogram does not match the second cryptogram, the method further includes performing a computation using the first cryptogram and the second cryptogram; and comparing a result of the computation with a stored set of results to recover a first data element carried by the second cryptogram.

    Abstract: Methods and device for personalizing a secure element (e.g., a eUICC) may include or implement operations for receiving a personalization request issued by an operator to download a personalized profile in compliance with a model into the secure element, and the request may include personalization data, an identifier of the secure element and the identifier of the model. Other operations may include using the identifier of the secure element to identify a pre-personalization server suitable for pre-personalizing the secure element; obtaining a message from the pre-personalization server, the message including a pre-personalization script for the secure element based on the description of the model; generating a personalization script for the secure element by using the pre-personalization script and the personalization data; and sending the personalization script to the secure element, the secure element being suitable for executing the personalization script to install the personalized profile in the secure element.

    Abstract: A method is provided for producing a smart card including at least one chip and another electronic component having a face accessible from the outside. The method includes: forming a card body having two opposing faces and in which at least two recesses are formed, one being a through-recess extending from one of the faces to the other, forming a first module including the chip and forming a second module separate from the first module and including the other electronic component, the second module including a support to which the component is secured opposite the face that must be accessible, securing the second module in the through-recess from the face of the body that is opposite the face through which the face of the component must be accessible, via a shoulder in the through-recess, and securing the first module in the other recess.

    Abstract: A method that may be performed by a profile management server for managing the profiles of a secure entity, such as an embedded universal integrated circuit card. The method may include sending a message to the secure entity in order to modify the active profile of the entity; initializing and starting a timer; and in the event that the server does not receive a message indicating which profile is active in the secure entity before the expiry of a predetermined duration after the starting of the timer, then starting an audit procedure for determining which profile is actually active in the secure entity.
