El c\u00f3digo est\u00e1 escrito en C y se distribuye bajo la licencia GPLv2. La implementaci\u00f3n es muy compacta y ocupa dos mil l\u00edneas de c\u00f3digo. Se ha declarado soporte para plataformas Linux, Windows, macOS, iOS, Android, enrutadores (Asus, Netgear, Linksys) y navegadores. Para compilar se requiere el uso de sistemas de construcci\u00f3n Earthly y Ceedling. La implementaci\u00f3n se presenta como una biblioteca que se puede utilizar para integrar funciones de cliente y servidor. <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/es\/vpn\/\"   title=\"VPN\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"176\">VPN<\/a> en sus aplicaciones.      <\/p>\n<p> El c\u00f3digo emplea funciones criptogr\u00e1ficas verificadas y disponibles mediante la biblioteca wolfSSL, que ya se utiliza en soluciones que han obtenido la certificaci\u00f3n FIPS 140-2. En modo normal, el protocolo utiliza UDP para la transmisi\u00f3n de datos y DTLS para establecer un canal de comunicaci\u00f3n cifrado. Como opci\u00f3n, para asegurar la operatividad en redes UDP poco fiables o limitadas, <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/es\/server\/dts-prohoster\/\"   title=\"el servidor\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"3016\">el servidor<\/a> se ofrece un modo de transmisi\u00f3n m\u00e1s fiable, aunque menos r\u00e1pido, que permite enviar datos a trav\u00e9s de TCP y TLSv1.3.    <\/p>\n<p>Las pruebas realizadas por ExpressVPN han demostrado que en comparaci\u00f3n con los antiguos protocolos (ExpressVPN soporta L2TP\/IPSec, OpenVPN, IKEv2, PPTP, WireGuard y SSTP, aunque no se detalla con qu\u00e9 exactamente se llev\u00f3 a cabo la comparaci\u00f3n), la transici\u00f3n a Lightway ha permitido reducir el tiempo de establecimiento de la conexi\u00f3n en un promedio de 2.5 veces (en m\u00e1s de la mitad de los casos, el canal de comunicaci\u00f3n se establece en menos de un segundo). El nuevo protocolo tambi\u00e9n ha permitido reducir en un 40% el n\u00famero de desconexiones en redes m\u00f3viles poco fiables con problemas de calidad en la conexi\u00f3n.    <\/p>\n<p>El desarrollo de la implementaci\u00f3n de referencia del protocolo se llevar\u00e1 a cabo en GitHub, ofreciendo la posibilidad de participaci\u00f3n en el desarrollo a representantes de la comunidad (para la transferencia de cambios es necesario firmar un acuerdo CLA sobre la transferencia de derechos de propiedad sobre el c\u00f3digo). Tambi\u00e9n se invita a colaborar a otros proveedores de VPN, que pueden utilizar el protocolo propuesto sin restricciones.        <\/p>\n<p>La seguridad de la implementaci\u00f3n ha sido confirmada por los resultados de una auditor\u00eda independiente realizada por Cure53, que previamente audit\u00f3 NTPsec, SecureDrop, Cryptocat, F-Droid y Dovecot. La auditor\u00eda abarc\u00f3 la revisi\u00f3n del c\u00f3digo fuente e incluy\u00f3 pruebas para identificar posibles vulnerabilidades (los temas relacionados con la criptograf\u00eda no fueron analizados). En general, la calidad del c\u00f3digo fue evaluada como alta; sin embargo, la revisi\u00f3n encontr\u00f3 tres vulnerabilidades que podr\u00edan llevar a una denegaci\u00f3n de servicio y una vulnerabilidad que permite usar el protocolo como amplificador de tr\u00e1fico en ataques DDoS. Los problemas mencionados ya han sido solucionados y se han considerado las observaciones para mejorar el c\u00f3digo. La auditor\u00eda tambi\u00e9n resalt\u00f3 las vulnerabilidades y problemas conocidos en los componentes de terceros involucrados, como libdnet, WolfSSL, Unity, Libuv y lua-crypt. En general, los problemas son menores, excepto el MITM en WolfSSL (CVE-2021-3336).<br \/>\n<br \/>Fuente: <a content=\"nofollow\" rel=\"nofollow\"
