    摘要: A process for the dissimulation of concealment of a secret code in a data authentication device by encrypting the secret code by an encrypting function for forming an image of the secret code and storing the secret code image in the authentication device. Beforehand, an encrypting function is chosen such that with each stored secret code image corresponds a plurality of antecedent codes all differing from the secret code, but which, once encrypted by the encrypting function have an image identical to that of the secret code. The secret code of a user has an authentication device in which is stored the secret code image.

    摘要: A process for controlling communication between a first and a second smart card using key-based cryptography is provided. In the disclosed process, a first identity code is stored in the first smart card and a second identity code is stored in the second smart card. The smart cards are customized by writing into each of the smart cards an identical group secret key and respective algorithms for processing the identical group secret key and the first and second identity codes stored in the first and second smart cards, respectively. The smart cards are used by transmitting the first identity code to the second smart card, transmitting the second identity code to the first smart card, and calculating using the respective processing algorithms stored in the smart cards, first and second session keys for the first and second smart cards, respectively.

    摘要: A process is provided for authentication in a data processing system using a data processing terminal having a programmable memory. The terminal supplies to a server an identify code (ID), the server checks the identify code, and in the case of agreement, supplies a random number (ALEA-A) to the terminal. The terminal encodes the random number using a signature algorithm (B) defined by a secret key (SID), and supplies a first signed random number (ALEA-S) to the server, which applies a signature checking algorithm (T, B, C) to the number (ALEA-S). The identity code and an encrypted secret key (KID) are written into the memory. The secret key (SID) used for the signature of the random number is determined using a decrypting algorithm (INVA) using the encrypted secret key (KID) and a password (MP) supplied by the terminal user. Particular utility for the present invention is found in the area of data processing, although other utilities are also contemplated.

    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: At least one expired decryption key intended to be used for asymmetrical decryption of encrypted data is recovered in a terminal after generation of a cryptographic encryption key/decryption key pair stored in a cryptographic medium such as a microchip card. The expired decryption key is stored in a database accessible to a user of the terminal and encrypted beforehand as a function of the new generated encryption key. In the terminal connected to the cryptographic medium, the encrypted expired encryption key is decrypted as a function of the decryption key stored in the cryptographic medium so that the encrypted data is decrypted as a function of the thus decrypted expired decryption key.

    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.
