  • Publication number: 20110092253
    Abstract: The invention provides a method for activating the subscription of an UICC, said UICC comprising an activation application, said method comprising the step of activating the subscription of the holder of the UICC by sending a message to an activation server, said message being sent by the activation application to the activation server by using an IP based communication.

  • Patent number: 7925878
    Abstract: A system and method for creating a trusted network capable of facilitating secure transactions via an open network using batch credentials, such as batch PKI certificates, is presented. A certificate is bound to a group, or batch, or devices. This certificate is referenced by an activation authority upon processing a request for service by a device. Information regarding the device batch certificate is maintained in a permanent, or escrow, database. A user identity is bound to a device, as a device key is used to sign a user key created on the device in the presence of the user, and a copy of the device key is later used to decrypt the signed user key upon its transmission and receipt.

  • Publication number: 20080276090
    Abstract: A chip card needs to be allocated in a secured manner to a network operator via a personalization center in order to determine a final authentication key which is attributed to a subscriber of the operator without its being transmitted via a network. The following is loaded into a card by a module: an algorithm and an allocation key; an algorithm for determination of the authentication key and at least one intermediate authentication key. A module transmits an allocation message which includes a final identity number, a random number and an allocation signature from the center to the card. The card authenticates the message by means of the allocation algorithm as a function of the allocation key and the allocation signature, and determines the final authentication key as a function of the intermediate key and the random number.

  • Patent number: 7222783
    Abstract: A device external to a terminal transmits a specific application identifier and an encrypted first key and number to a first chip card in service in the terminal. In the first card, if the decrypted first number satisfies a first condition, the specific application is called up, application data are read, the data are encrypted using the decrypted first key to transmit them to the external device, and the application is made inoperable. Following replacement of the first card by a second card, the external device transmits the identifier and an encrypted second key and number to the second card. In the latter, if the decrypted second number satisfies a second condition, the encrypted data are transmitted to the second card so that the latter calls up the application, decrypts the encrypted data using the decrypted second key and installs said data.

  • Publication number: 20050279826
    Abstract: Transfer of data between two chip cards A means (SS, CT) external to a terminal (TM) transmits a specific application identifier and an encrypted first key and number to a first chip card (CA) in service in the terminal. In the first card, if the decrypted first number satisfies a first condition, the specific application is called up, application data are read, the data are encrypted using the decrypted first key in order to transmit them to the external means, and the application is made inoperable. Following replacement of the first card by a second card (CB), the external means transmits the identifier and an encrypted second key and number to the second card. In the latter, if the decrypted second number satisfies a second condition, the encrypted data are transmitted to the second card so that the latter calls up the application, decrypts the encrypted data using the decrypted second key and installs said data.
