Abstract

Un método comprende:generando un isógeno que traza una pluralidad de puntos desde una primera curva elíptica hacia una segunda curva elíptica;publicando una clave pública que corresponde al isógeno;encriptando un mensaje que usa una clave de encriptación que corresponde al isógeno; yque descifra el mensaje encriptado que usa una clave de descencriptación correspondiendo al isógeno. Un método como el citado por la reivindicación 1 , en qué por lo menos una clave de encriptación o de descencriptación es una clave privada, la clave privada siendo un isógeno dual del isógeno. Un método como el citado por la reivindicación 1, en donde el isógeno se genera usando una técnica seleccionada de un grupo que comprende una generación múltiple compleja, una generación modular, una generación linealmente independiente, y combinaciones de ellas. SOLICITUDES DE PATENTES DE MODELO DE UTILIDADORDENADAS PUBLICAR EN MARZO DE 2006 IMPORTANTE:SOLICITUDES DE PATENTE DE MODELO DE UTILIDAD: A partir de la fecha de publicación de esta gaceta el solicitante cuenta con un plazo de tres (3) meses para pedir que se practique el examen de patentabilidad de la solicitud, anexando el recibo de pago de la tasa correspondiente a tal fin.
