Abstract
(EN) The invention provides a method of verifiable generation of public keys. According to the method, a self-signed signature is first generated and then used as input to the generation of a pair of private and public keys. Verification of the signature proves that the keys are generated from a key generation process utilizing the signature. A certification authority can validate and verify a public key generated from a verifiable key generation process.
(FR) L'invention concerne un procédé de production vérifiable de clés publiques, consistant à produire d'abord une auto-signature, que l'on utilise ensuite comme entrée pour la production d'une paire de clés privée et publique. La vérification de la signature prouve que les clés sont issues d'un processus de production reposant sur la signature. Une autorité de certification peut ainsi valider et vérifier une clé publique établie à partir d'un processus de production de clé vérifiable.
