摘要： A traceable method for encrypting and/or decrypting data broadcast by at least one transmitter towards several decoders includes the steps: during encryption of broadcast data, the transmitter implements (in 86) at least one first secret function to transform an unencrypted message into an encrypted message; and during decryption of the broadcast data, all the decoders implement (in 92) at least one common second secret function, each decoder using therefor a mathematical description of the second function stored in a memory (21), the mathematical description of the second function being different from one decoder to another or from one group of decoders to another such that the mathematical description used identifies exclusively the particular decoder or group of decoders.

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： A process for the identification of a claimant by a verifier. The process is of the public key type, where the public exponent is equal to 3. The claimant draws at random a first exponent .alpha., calculates r=g.sup..alpha. mod n and transmits R=r.sup.3. The verifier draws at random a second exponent .beta., calculates t=g.sup..beta. mod n, calculates T=t.sup.3 mod n and h=H.sub.1 (Z), where H.sub.1 is a hash function, and calculates Z=R.sup.3 mod n. The verifier transmits to the claimant the numbers T and h. The claimant calculates Y=T.sup..alpha. mod n, verifies the result H.sub.1 (Y), calculates H=H.sub.2 (Y), where H.sub.2 is another hash function, calculates z=rS mod n, and transmits z and H. The claimant also has a secret number S equal to the modulo n cubic root of a number I deduced from its identity so that the number S verifies S.sup.3 =I mod n. The verifier verifies that H received is equal to H.sub.2 (Z) and that z.sup.3 is equal to RI mod n.

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 cryptographic process is for protection against fraud. An allocation of a secret key K is made to a card and to an application and an input value R is defined. The card and application calculate the modulo 2 scalar product of binary vectors constituted by words of R and words of K. The application checks whether the result obtained by the card is in agreement with its own result. An exemplary application is low cost cards.

摘要： Example wireless feedback control systems disclosed herein include a receiver to receive a first measurement of a target system via a first wireless link. Disclosed example systems also include a neural network to predict a value of a state of the target system at a future time relative to a prior time associated with the first measurement, the neural network to predict the value of the state of the target system based on the first measurement and a prior sequence of values of a control signal previously generated to control the target system during a time interval between the prior time and the future time, and the neural network to output the predicted value of the state of the target system to a controller. Disclosed example systems further include a transmitter to transmit a new value of the control signal to the target system via a second wireless link.

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.
