Lors d'Eurocrypt 2011, Lindell a présenté des schémas d'engagement pratiques, statiques et adaptatifs, sécurisés UC, basés sur l'hypothèse DDH. Plus tard, Blazy et al. (à l'ACNS 2013) a amélioré l'efficacité des programmes d'engagement de Lindell. Dans cet article, nous présentons des schémas d'engagement statiques et adaptatifs sécurisés UC basés sur la même hypothèse et améliorons encore la complexité de communication et de calcul, ainsi que la taille de la chaîne de référence commune.

Abstract: At Eurocrypt 2011, Lindell presented practical static and adaptively UC-secure commitment schemes based on the DDH assumption. Later, Blazy et al. (at ACNS 2013) improved the efficiency of the Lindell's commitment schemes. In this paper, we present static and adaptively UC-secure commitment schemes based on the same assumption and further improve the communication and computational complexity, as well as the size of the common reference string.
