Abstract

Un procedimiento de firma de un mensaje (m) llevado a cabo por unos medios de tratamiento de un dispositivo usuario de un miembro (Mi) perteneciente a un grupo de miembros (G) generado por una autoridad de gestión de claves, poseyendo dicho dispositivo usuario una clave de firma secreta (ski), que comprende una etapa de generación (E301) para el mensaje (m) de una firma de grupo (σ) que permite a dicho miembro (Mi) probar su pertenencia al grupo de miembros (G) y una etapa de generación (E302) de un seudónimo (nymij) que identifica al miembro (Mi) dentro de un dominio (Dj) de un proveedor de servicios (SPj), comprendiendo dicho dominio un conjunto de terminales en comunicación con un servidor de dicho proveedor de servicios, estando dicha firma de grupo (σ) construida de manera tal que dicho miembro (Mi) puede probar al firmar el mensaje (m) su conocimiento de dicha clave de firma secreta sin divulgarla, y caracterizado por que dicha firma de grupo (σ) está construida de manera tal que la pertenencia del miembro (MI) al grupo es verificable independientemente del seudónimo (nymij), y por que la clave de firma secreta (ski) del miembro (Mi) comprende por lo menos una primera parte de clave (fi) generada por los medios de tratamiento del dispositivo usuario de dicho miembro y desconocido por la autoridad de gestión de las claves, y por que dicho seudónimo y dicha firma son función de una segunda parte (xi) de dicha clave de firma secreta del miembro (Mi), y están construidos de manera tal que prueban que el miembro identificado por el seudónimo es el firmante del mensaje (m) y por que dicho seudónimo (nymij) del miembro (Mi) es específico para el dominio (Dj).
