Les systèmes d'engagement Trapdoor sont largement utilisés pour ajouter des propriétés précieuses aux signatures ordinaires ou pour améliorer la sécurité des signatures faiblement sécurisées. Dans cette lettre, nous proposons un schéma d'engagement trappe basé sur la fonction RSA, et prouvons sa sécurité sous la dureté de la factorisation entière. Notre schéma est très efficace pour calculer un engagement. Surtout, cela ne nécessite que trois multiplications pour évaluer un engagement lorsque e=3 est utilisé comme exposant public de la fonction RSA. De plus, notre schéma possède deux propriétés utiles, la liberté d'exposition des clés et la forte ouverture de la trappe, qui sont utiles pour concevoir des schémas de signature caméléon sécurisés et convertir une signature faiblement sécurisée en une signature fortement sécurisée, respectivement.

Abstract: Trapdoor commitment schemes are widely used for adding valuable properties to ordinary signatures or enhancing the security of weakly secure signatures. In this letter, we propose a trapdoor commitment scheme based on RSA function, and prove its security under the hardness of the integer factoring. Our scheme is very efficient in computing a commitment. Especially, it requires only three multiplications for evaluating a commitment when e=3 is used as a public exponent of RSA function. Moreover, our scheme has two useful properties, key exposure freeness and strong trapdoor opening, which are useful for designing secure chameleon signature schemes and converting a weakly secure signature to a strongly secure signature, respectively.
