    Abstract: A method for operating an attribute assertion device having a processor and memory to create an unlinkable digital signature-equivalent of an assertion message that is verifiable—by a service provider receiving the unlinkable digital signature-equivalent—as being generated from a digital signature of a known attribute provider having a public key PKAP. Operating the processor of the attribute assertion device to transform a digital signature of the attribute message into an unlinkable digital signature-equivalent using a one-way transformation of the signature, with the transformation process using a random value generated by the attribute assertion device and a challenge provided by the service provider.

    Abstract: This invention relates to a method for managing the status of a connected device by publishing assertions in an immutable distributed database composed of a plurality of compute nodes, a pair of keys comprising a public key and a private key being associated with the connected device. The method comprises the steps of: receiving from a first terminal associated to a first user an instruction message; verifying that the first user is allowed to modify the status of the connected device; sending an assertion request to the immutable distributed database for publishing an assertion comprising the status information.

    Abstract: The invention is a method for managing an application that includes a generic part and an additional part. The generic part is pre-installed on a device. The device gets a fingerprint of itself and after a user authentication sends to a server a request for getting the additional part. The request comprises credentials associated with the user or a reference of the user, the fingerprint and a reference of the application. The server generates a ciphered part of the additional part using a key based on both the credentials and the fingerprint and builds an auto-decrypt program configured to decipher the ciphered part. The device receives the ciphered part and the auto-decrypt program. It gets the fingerprint and the credentials and retrieves the additional part by running the auto-decrypt program with said fingerprint and credentials as input parameters.

    Abstract: The invention is a method for managing a secure channel between a server and a secure element embedded in a first device, wherein a user agent embedded in a second device establishes a HTTPS session with the server and retrieves a web application from the server, the method comprising the steps: the server sends to the web application an application certificate which is linked to a specific data reflecting the identity of the server, the secure element gets the application certificate and the specific data, the secure element checks the validity of the application certificate and that the application certificate is consistently linked to the specific data, in case of successful checks, the secure element and the server generate an ephemeral session key and use it for opening a secure channel.

    Abstract: The invention specifically relates to a method for virtually connecting two persons, with the first person having a first NFC device and the second person having a second NEC device. One of the NFC devices is a telecommunications terminal comprising an application, and both NFC devices comprise the identity of the person to which they belong. According to the invention, the method includes transmitting the identity of the first person from the first NFC device to the second NFC device; transmitting the identity of the second person from the second NFC device to the first NFC device; generating a secret shared by the persons using the application, with the shared secret giving access to an Internet space shared by the persons; and storing the shared secret in the NFC devices, with a reference relating to the virtual connection thereof.

    Abstract: The invention is a method for deploying a trusted identity for a user issued by an issuer. The user has a user device configured to send a request for signature to an issuer device handled by the issuer. The request comprises a user public key allocated to the user. The issuer device is configured to compute an issuer signature by signing both the user's trusted identity and the user public key using an issuer private key allocated to the issuer. A block chain transaction containing the issuer signature is created and submitted to a Block Chain for transaction verification and storage.
