L'azienda ExpressVPN ha annunciato l'apertura del codice sorgente dell'implementazione del protocollo Lightway, sviluppato per garantire un tempo di connessione minimo mantenendo un alto livello di sicurezza e affidabilit\u00e0. Il codice \u00e8 scritto in C ed \u00e8 distribuito con licenza GPLv2. L'implementazione \u00e8 molto compatta e si \u00e8 adattata in duemila righe di codice. \u00c8 dichiarato il supporto per le piattaforme Linux, Windows, macOS, iOS, Android, router (Asus, Netgear, Linksys) e browser. Per la compilazione \u00e8 necessario utilizzare i sistemi di build Earthly e Ceedling. L'implementazione \u00e8 presentata come una libreria, che pu\u00f2 essere utilizzata per integrare le funzioni client e server. VPN<\/a> nelle proprie applicazioni. <\/p>\n

Nel codice sono impiegate funzioni crittografiche consolidate fornite dalla libreria wolfSSL, gi\u00e0 utilizzata in soluzioni che hanno ottenuto la certificazione FIPS 140-2. In modalit\u00e0 standard, il protocollo utilizza UDP per la trasmissione dei dati e DTLS per creare un canale di comunicazione crittografato. Come opzione per garantire il funzionamento in reti UDP inaffidabili o restrittive, server<\/a> \u00e8 disponibile una modalit\u00e0 di streaming pi\u00f9 affidabile, ma meno veloce, che consente di trasmettere dati su TCP e TLSv1.3. <\/p>\n

I test condotti da ExpressVPN hanno dimostrato che, rispetto ai protocolli precedenti (ExpressVPN supporta L2TP\/IPSec, OpenVPN, IKEv2, PPTP, WireGuard e SSTP, ma non specifica a cosa siano stati confrontati), il passaggio a Lightway ha permesso di ridurre il tempo di connessione in media di 2,5 volte (in oltre la met\u00e0 dei casi, il canale di comunicazione si stabilisce in meno di un secondo). Il nuovo protocollo ha anche consentito di ridurre del 40% il numero di interruzioni delle connessioni in reti mobili inaffidabili con problemi di qualit\u00e0 del segnale. <\/p>\n

Lo sviluppo dell'implementazione di riferimento del protocollo avverr\u00e0 su GitHub, offrendo la possibilit\u00e0 di partecipare agli sviluppi da parte dei rappresentanti della comunit\u00e0 (per inoltrare modifiche \u00e8 necessario firmare un accordo CLA di trasferimento dei diritti su codice). Sono invitati a collaborare anche altri fornitori di VPN, che possono utilizzare il protocollo proposto senza restrizioni. <\/p>\n

La sicurezza della realizzazione \u00e8 stata convalidata dai risultati di un audit indipendente condotto da Cure53, che in passato ha realizzato audit per NTPsec, SecureDrop, Cryptocat, F-Droid e Dovecot. L'audit ha incluso il controllo dei codici sorgente e ha comportato test per identificare potenziali vulnerabilit\u00e0 (le questioni legate alla crittografia non sono state esaminate). In generale, la qualit\u00e0 del codice \u00e8 stata valutata come alta, tuttavia, l'analisi ha identificato tre vulnerabilit\u00e0 che possono portare a interruzioni del servizio e una vulnerabilit\u00e0 che consente di utilizzare il protocollo come amplificatore di traffico in attacchi DDoS. I problemi segnalati sono stati gi\u00e0 risolti e i suggerimenti per migliorare il codice sono stati presi in considerazione. L'audit ha anche esaminato vulnerabilit\u00e0 e problemi noti nei componenti di terze parti coinvolti, come libdnet, WolfSSL, Unity, Libuv e lua-crypt. In generale, i problemi sono di poca importanza, ad eccezione di un problema MITM in WolfSSL (CVE-2021-3336).
