El funcionamiento de los criptosistemas asim\u00e9tricos se basa en operaciones matem\u00e1ticas unidireccionales que son f\u00e1ciles de calcular en un sentido pero extremadamente dif\u00edciles de revertir sin conocer ciertos par\u00e1metros secretos.<\/p>\n\n\n\n

Proceso b\u00e1sico de funcionamiento:<\/strong><\/p>\n\n\n\n

    \n
  1. Generaci\u00f3n de claves:<\/strong> Cada usuario genera un par de claves (p\u00fablica y privada) mediante algoritmos especializados.<\/li>\n\n\n\n
  2. Distribuci\u00f3n:<\/strong> La clave p\u00fablica se distribuye libremente, mientras la privada se mantiene en secreto.<\/li>\n\n\n\n
  3. Cifrado:<\/strong> El remitente utiliza la clave p\u00fablica del destinatario para cifrar el mensaje.<\/li>\n\n\n\n
  4. Descifrado:<\/strong> Solo el poseedor de la clave privada correspondiente puede descifrar el mensaje.<\/li>\n<\/ol>\n\n\n\n

    Algoritmos representativos:<\/strong><\/p>\n\n\n\n

      \n
    1. RSA (Rivest-Shamir-Adleman):<\/strong> Basado en la dificultad de factorizar el producto de dos n\u00fameros primos grandes. Es vers\u00e1til y se utiliza tanto para cifrado como para firmas digitales.<\/li>\n\n\n\n
    2. DSA (Digital Signature Algorithm):<\/strong> Dise\u00f1ado espec\u00edficamente para firmas digitales, basado en el problema del logaritmo discreto.<\/li>\n\n\n\n
    3. ECC (Elliptic Curve Cryptography):<\/strong> Utiliza propiedades de curvas el\u00edpticas sobre campos finitos, ofreciendo la misma seguridad que RSA pero con claves m\u00e1s cortas.<\/li>\n\n\n\n
    4. Diffie-Hellman:<\/strong> Permite el establecimiento de una clave compartida a trav\u00e9s de un canal inseguro sin necesidad de intercambiar claves previamente.<\/li>\n\n\n\n
    5. ElGamal:<\/strong> Sistema basado en el problema del logaritmo discreto, usado tanto para cifrado como para firmas digitales.<\/li>\n<\/ol>\n\n\n\n
