摘要： A ring-signature scheme is adapted so that at least one of the variability parameter values used is an identity trace of the anonymous signatory, determined as a function of anonymity withdrawal data stored and held secret by an anonymity withdrawal entity in connection with an identification of the anonymous signatory. This provides a subsequent controlled capacity of withdrawing the anonymity of the signatory, either by an authority, or by the signatory himself.

摘要： The cryptographic resources are supplied by at least one cryptographic source having a specific access interface. The application is presented with a mutualized interface substantially independent of the cryptographic sources and of their respective access interfaces. A translation module is placed between the mutualized interface and each interface for accessing a cryptographic source to provide access to the cryptographic resources from the application via the mutualized interface.

摘要： For signing of data by a given one of M delegates mandated by N titleholders, where M≧2 and N=1 or M=1 and N≧2, the terminal of the given delegate reads in a delegation server information on the delegates and the titleholders of the group thus constituted. The data and the information read and a private key of the given delegate are applied to a cryptographic algorithm to produce a signature which therefore carries a cryptographic delegation mark. The data, information, and signature are transmitted to a user terminal that can trace the characteristics of the signature delegation.

摘要： In order to apply an electronic signature from a client station having authentication resources at a server, the following steps are carried out: the client station is authenticated at the server, thus establishing an authenticated communication channel; a private key/public key pair is generated at the client station; a signature certificate request generated by means of at least the public key is transmitted from the client station to the server via the authenticated channel; a signature certificate obtained in response to the request is returned via the authenticated channel; this certificate is verified at the client station; an electronic signature is calculated at the client station by means of the private key, after which this private key is destroyed; and the calculated signature is formatted with the aid of the signature certificate received via the authenticated channel.

摘要： A device is provided for controlling secure transactions using a physical device held by a user and bearing at least one first pair of asymmetric keys, including a first device public key and a first corresponding device private key. The control includes, prior to implementing the device, certifying a first device public key and characteristics data of the physical device by signing with a first certification key, delivering a factory certificate, after verifying that the device private key is housed in a tamper-proof zone of the physical device. At least one second pair of asymmetric keys is generated, including a second device public key and a second device private key housed in a tamper-proof zone of the device. A second device public key is certified by signing with at least the first device private key, delivering a provisional certificate. The factory and provisional certificate are verified using, respectively, a second certification key corresponding to the first certification key, and the first device public key. In case of positive verification, the method includes delivering by a trusted third party a device certificate corresponding to the signature by the provider at least the second device public key and an identifier of the user and the characteristic data of the device.

摘要： This method provides for electronic certificate assignment in a certificate assignment infrastructure distributed in a network. The infrastructure includes at least one certificate server, an identity server and a registration server linked to the network. Prior to a certificate application request, information relating to the identity of a certificate applicant is stored in the identity server, the identity information being accessible by way of an identifier. In this method, an applicant requests a certificate from the registration server; the identifier is dispatched to the identity server; after verification of the identifier, the identity server dispatches the previously registered identity of the applicant, said identity being provided to the registration server; after receipt of the identity, the registration server dispatches a certificate request including the identity of the applicant to the certificate server, and the certificate server dispatches the certificate destined for the applicant.

摘要： The invention relates to a public key cryptographic method and system, a certification server and memories adapted for said system. In said public key cryptographic system, there is insufficient information contained in an electronic public key certificate alone to retrieve the public key. The inventive system comprises at least a second memory (52, 72) in which complementary information is stored, which can be used to retrieve the public key when used together with the information contained in the certificate. According to the invention, access to said complementary information is reserved to a limited number of authorised terminals among the group of terminals that can verify the certificate signature.
