A empresa ExpressVPN anunciou a abertura do c\u00f3digo fonte da implementa\u00e7\u00e3o do protocolo Lightway, projetado para alcan\u00e7ar o menor tempo de conex\u00e3o poss\u00edvel enquanto mant\u00e9m um alto n\u00edvel de seguran\u00e7a e confiabilidade. O c\u00f3digo \u00e9 escrito em C e distribu\u00eddo sob a licen\u00e7a GPLv2. A implementa\u00e7\u00e3o \u00e9 muito compacta e cabe em duas mil linhas de c\u00f3digo. O suporte \u00e9 declarado para as plataformas Linux, Windows, macOS, iOS, Android, roteadores (Asus, Netgear, Linksys) e navegadores. Para a compila\u00e7\u00e3o, \u00e9 necess\u00e1rio utilizar os sistemas de build Earthly e Ceedling. A implementa\u00e7\u00e3o \u00e9 apresentada na forma de uma biblioteca que pode ser utilizada para integrar funcionalidades de cliente e servidor. VPN<\/a> em seus aplicativos. <\/p>\n

No c\u00f3digo, foram utilizadas fun\u00e7\u00f5es de criptografia j\u00e1 testadas, fornecidas pela biblioteca wolfSSL, j\u00e1 utilizada em solu\u00e7\u00f5es que obtiveram a certifica\u00e7\u00e3o FIPS 140-2. No modo padr\u00e3o, o protocolo utiliza UDP para transmiss\u00e3o de dados e DTLS para estabelecer um canal de comunica\u00e7\u00e3o criptografado. Como op\u00e7\u00e3o para garantir funcionamento em redes UDP n\u00e3o confi\u00e1veis ou restritivas, servidor<\/a> \u00e9 oferecido um modo de transmiss\u00e3o mais confi\u00e1vel, mas menos r\u00e1pido, que permite a transmiss\u00e3o de dados sobre TCP e TLSv1.3. <\/p>\n

Os testes realizados pela ExpressVPN mostraram que, em compara\u00e7\u00e3o com os protocolos antigos (a ExpressVPN suporta L2TP\/IPSec, OpenVPN, IKEv2, PPTP, WireGuard e SSTP, mas n\u00e3o detalha com o que exatamente foi feita a compara\u00e7\u00e3o), a transi\u00e7\u00e3o para Lightway reduziu o tempo de conex\u00e3o em m\u00e9dia em 2,5 vezes (em mais da metade dos casos, o canal de comunica\u00e7\u00e3o \u00e9 estabelecido em menos de um segundo). O novo protocolo tamb\u00e9m permitiu reduzir em 40% o n\u00famero de interrup\u00e7\u00f5es de conex\u00e3o em redes m\u00f3veis n\u00e3o confi\u00e1veis com problemas de qualidade de sinal. <\/p>\n

O desenvolvimento da implementa\u00e7\u00e3o de refer\u00eancia do protocolo ser\u00e1 feito no GitHub, com a possibilidade de participa\u00e7\u00e3o de representantes da comunidade no desenvolvimento (para enviar altera\u00e7\u00f5es, \u00e9 necess\u00e1rio assinar um acordo de transfer\u00eancia de direitos autorais sobre o c\u00f3digo). Outros provedores de VPN tamb\u00e9m s\u00e3o convidados a colaborar, podendo utilizar o protocolo proposto sem restri\u00e7\u00f5es. <\/p>\n

A seguran\u00e7a da implementa\u00e7\u00e3o foi confirmada pelos resultados de uma auditoria independente realizada pela Cure53, que anteriormente auditou o NTPsec, SecureDrop, Cryptocat, F-Droid e Dovecot. A auditoria incluiu a verifica\u00e7\u00e3o do c\u00f3digo-fonte e a realiza\u00e7\u00e3o de testes para identificar poss\u00edveis vulnerabilidades (quest\u00f5es relacionadas \u00e0 criptografia n\u00e3o foram abordadas). De modo geral, a qualidade do c\u00f3digo foi avaliada como alta, mas, ainda assim, a verifica\u00e7\u00e3o revelou tr\u00eas vulnerabilidades que podem levar a uma nega\u00e7\u00e3o de servi\u00e7o, e uma vulnerabilidade que permite usar o protocolo como amplificador de tr\u00e1fego em ataques DDoS. Os problemas mencionados j\u00e1 foram corrigidos, e as sugest\u00f5es para melhorar o c\u00f3digo foram consideradas. A auditoria tamb\u00e9m destacou vulnerabilidades conhecidas e problemas em componentes de terceiros envolvidos, como libdnet, WolfSSL, Unity, Libuv e lua-crypt. Na sua maioria, os problemas foram considerados insignificantes, exceto um MITM no WolfSSL (CVE-2021-3336).
