Abstract

Método para proteger información confidencial. Comprende: i) cifrar información por medio de una clave pública generada por una tercera parte de confianza (T); y ii) descifrar, un usuario o miembro (U1, U2, ..., Ut) de un grupo de usuarios autorizados (U), dicha información cifrada por medio de una clave privada generada por dicha tercera parte de confianza (T). Comprende además generar, por dicha tercera parte de confianza (T), dicha clave pública como una clave pública común y una pluralidad de claves privadas diferentes, una para cada uno de dichos usuarios (U1, U2, ..., Ut), estando asociadas cada una de dicha pluralidad de claves privadas diferentes a dicha clave pública común y pudiendo utilizarse para dicha etapa de descifrado ii).
