Abstract

Un sistema de firma multi-etapa y método usa dispositivos de firma multiples para fijar una firma unica que puede ser verificada usando una clave verificacion publica unica. Cada dispositivo de firma posee una porcion de la clave de firma y fija una firma parcial en respuesta a la autorizacion desde una pluralidad de agentes de autorizacion; en una modalidad serial, después de que una primer firma parcial ha sido fijada, un segundo dispositivo de firma exponencia la primera firma paracial; en una modalidad paralela, cada dispositivo de firma , fija una firma parcial, y la pluralidad de firmas parciales son multiplicada juntas para formar la firma final; la seguridad del sistema es provida por las capacidadesd de distribucion para fijar firmas entre una pluralidad de dispositivos de firma y para distribuir autoridades a firmas paraciales fijas entre una pluralidad de agentes de autorizacion.
