Abstract

Une clé publique (PK) dépendant d'une clé secrète est accessible à une entité émettrice (2) et à des entités réceptrices. Une clé privée associable à une entité réceptrice dépend de la clé secrète et d'un paramètre d'identité (IDj) de cette entité. Le chiffrement d'un message (M) à destination d'un ensemble de s entités réceptrices (s > 1) comprend la génération d'une clé de chiffrement symétrique (K) et un cryptogramme (Hdr) associé, en fonction de la clé publique, des paramètres d'identité des s entités réceptrices et d'un nombre choisi par l'entité émettrice. Le cryptogramme donne accès à la clé de chiffrement associée par combinaison avec la clé publique, les paramètres d'identité des s entités réceptrices et la clé privée d'une entité réceptrice identifiée de l'ensemble. Le message est chiffré dans l'entité émettrice avec la clé de chiffrement générée et diffusé sous cette forme chiffrée, accompagné dudit cryptogramme.
