Abstract: A method is intended for transforming a secure electronic device, associated to a first identifier and having a sensitive mode disabled after production, for a new sensitive use. This method comprises the steps of: (i) externally computing a cipher of the first identifier with a predetermined function fed with this first identifier and a predetermined secret key; (ii) transforming an accessible metal layer of the electronic device to form an activation pattern representing this externally computed cipher of the first identifier; (iii) getting a value representative of this activation pattern into the electronic device; and (iv) computing a second identifier with this transformed electronic device by feeding a reverse function of the predetermined function with this value and this secret key, to trigger a comeback to the sensitive mode if this second identifier is equal to the first identifier.

Abstract: The invention concerns a method for managing content on a secure element connected to an equipment, this content being managed on the secure element from a distant administrative platform. According to the invention, the method consists in: establishing, at the level of the administrative platform a secure channel between the equipment and the administrative platform, thanks to session keys generated by the secure element and transmitted to the equipment; transmitting to the administrative platform a request to manage content of the secure element; and verifying at the level of the administrative platform that this request originates from the same secure element that has generated the session keys and, if positive, authorizing the management and, if negative, forbid this management.

Abstract: The present invention relates to a method to protect, in a secured container using an encryption key, a set of mixed sensitive and public data to be transferred to an entity. The method includes the steps of: generating a random key, ciphering the set of mixed sensitive and public data using said random key to obtain a ciphered set of data, generating an initialization value, and defining configuration information for the secured container. The initialization value, the configuration information and random key form a preamble. The preamble and the ciphered set of data are encrypted. The initialization value renders the resulting encrypted data variable from a secured container to another even in case of repetitive configuration information in the preamble.

Abstract: The invention is a method of managing an object which is represented by a first instance of a class. The first instance is stored in a secure element comprising an initial operating system. The method comprises a step of updating the initial operating system to generate an updated operating system, a step of creating a metadata uniquely associated with the object, said metadata being permanently stored in the secure element and comprising a value of a parameter of said class which has been used to create said first instance. The method comprises a step of re-instantiating the object by generating an updated instance of the class in the updated operating system by using said value to set said parameter of the class, said updated instance representing the object. The re-instantiating step is automatically triggered by the step of updating the initial operating system.
