  • Patent number: 11593805
    Abstract: A system for authenticating an electronic device by means of an authentication server in order to authenticate a user of said electronic device. The system is adapted to perform an authentication based on a fictive payment transaction and includes the authentication server which is adapted to execute a fictive payment transaction with a predetermined transaction amount with said electronic device and during said execution to receive a first cryptogram from said electronic device; send said first cryptogram to a banking server; and receive from said banking server an acknowledgment if said first cryptogram is valid; when said fictive payment transaction has been executed, compute an authentication identification based on said electronic device's data; said electronic device which is a payment electronic device and which is adapted to execute said fictive payment transaction with said authentication server and during said execution to send said first cryptogram to said authentication server.

  • Publication number: 20190268169
    Abstract: This invention relates to a physical key for provisioning a communication device with data allowing said communication device to access a vehicle resource by operating remotely a vehicle lock system in which a first cryptographic key called master key is stored, comprising a secure enclave also storing the master key, the physical key being configured to: establish a communication link with the communication device; derive by the secure enclave a second cryptographic key called derived key from the master key; transmit to the communication device via the secure communication link the derived key for enabling the communication device to answer a security challenge from the vehicle lock system and the vehicle lock system to verify said answer, the access to the vehicle resource being allowed if the answer is successfully verified.

  • Patent number: 9825917
    Abstract: Method and System for enhanced privacy in privacy-preserving identity solutions. The technology provides for a redirect of a request to generate a proof of an attribute from a service provider to a separator. The separator removes source identification from the attribute-proof request and redirects the attribute-proof request, free of original source identification, to a credential issuer which issues the credential. A security device of the user generates a presentation token from the privacy-preserving credential and presents the presentation token to the service provider as proof of the attribute. Other systems and methods are disclosed.

  • Patent number: 9124563
    Abstract: A method to securely and asynchronously provisioning keys from one source secure device to a target secure device through a key provisioning server, in which the keys to be provisioned via the method remain unknown. The method includes the steps of, for the source secure device, encrypting a key to be transferred using a transport key so that only the target secure device can decrypt, and sending the encrypted key to the provisioning server and, for the target secure device, when available, getting the encrypted transferred key, and decrypting the transferred key using the transport key.

  • Patent number: 8200937
    Abstract: The invention is a method of managing flash memory-allocation in an electronic token. Said token has a memory comprising a list area and a managed area. Said managed area comprises allocated spaces and at least one free memory chunk. Said list area comprises at least one valid entry referencing a free memory chunk. Said valid entry comprises a state field. Said method comprises the step of selecting a free memory chunk further to an allocation request where said free memory chunk is referenced by an old entry, and the step of identifying a new allocated space in the selected free memory chunk. The state field of said valid entry is preset with a virgin state. Said method comprises the step of invalidating the old entry referencing the selected free memory chunk.
