Abstract

L'invention concerne un procédé de signature numérique d'un message M par un signataire ayant une identité I et disposant d'un dispositif de signature, ledit procédé utilisant un schéma de cryptographie à clé publique et étant caractérisé en ce que le signataire dispose d'une clé publique Kp et de deux dés privées Ks et K0 la seconde dé privée Kc étant déposée auprès d'un tiers de confiance, et en ce qu'il comporte, pour chaque opération de signature, deux étapes complémentaires réalisées chacune avec une clé privée distincte, à savoir : - le calcul par le signataire d'une pré-signature Ss du message M à l'aide de sa première clé privée Ks, puis la transmission du message M et de la pré-signature Ss au tiers de confiance; - la vérification par le tiers de confiance de la pré-signature Ss, suivie du calcul par le tiers de confiance d'une signature S du message M, à l'aide d'une part de la seconde clé privée Kc du signataire déposée auprès du tiers de confiance, et d'autre part de ladite pré-signature Ss préalablement calculée par le signataire.
