La criptograf\u00eda de clave p\u00fablica, tambi\u00e9n conocida como criptograf\u00eda asim\u00e9trica, representa uno de los avances m\u00e1s revolucionarios en la seguridad de la informaci\u00f3n. A diferencia de los sistemas tradicionales, este modelo utiliza dos claves matem\u00e1ticamente relacionadas pero computacionalmente distintas: una clave p\u00fablica que puede compartirse libremente y una clave privada que debe mantenerse en secreto.<\/p>\n\n\n\n

Este paradigma, introducido por Whitfield Diffie y Martin Hellman en 1976, resolvi\u00f3 el problema fundamental de la distribuci\u00f3n segura de claves que afectaba a los sistemas sim\u00e9tricos. El principio fundamental radica en que los mensajes cifrados con la clave p\u00fablica solo pueden descifrarse con la correspondiente clave privada, mientras que la informaci\u00f3n firmada con la clave privada puede verificarse con la clave p\u00fablica.<\/p>\n\n\n\n

Los criptosistemas de clave p\u00fablica basan su seguridad en problemas matem\u00e1ticos computacionalmente dif\u00edciles, como la factorizaci\u00f3n de n\u00fameros enteros grandes, el logaritmo discreto o las curvas el\u00edpticas, que resultan pr\u00e1cticamente imposibles de resolver con la capacidad computacional actual.<\/p>\n\n\n\n
