Compania ExpressVPN a anun\u021bat deschiderea codului surs\u0103 pentru implementarea protocolului Lightway, dezvoltat pentru a atinge un timp minim de conectare, p\u0103str\u00e2nd \u00een acela\u0219i timp un nivel \u00eenalt de securitate \u0219i fiabilitate. Codul este scris \u00een limbajul C \u0219i este distribuit sub licen\u021ba GPLv2. Implementarea este foarte compact\u0103 \u0219i se \u00eencadreaz\u0103 \u00een dou\u0103 mii de linii de cod. Se declar\u0103 suport pentru platformele Linux, Windows, macOS, iOS, Android, routere (Asus, Netgear, Linksys) \u0219i browsere. Pentru compilare, este necesar\u0103 utilizarea sistemelor de compilare Earthly \u0219i Ceedling. Implementarea este realizat\u0103 sub form\u0103 de bibliotec\u0103, care poate fi utilizat\u0103 pentru a integra func\u021biile clientului \u0219i serverului. VPN<\/a> \u00een aplica\u021biile sale. <\/p>\n

\u00cen cod sunt folosite func\u021bii criptografice dovedite, furnizate de biblioteca wolfSSL, deja utilizat\u0103 \u00een solu\u021bii certificate FIPS 140-2. \u00cen mod normal, protocolul folose\u0219te UDP pentru transmiterea datelor \u0219i DTLS pentru crearea unui canal de comunicare criptat. Ca op\u021biune pentru a asigura func\u021bionarea \u00een re\u021belele UDP nesigure sau restrictive, serverul<\/a> se ofer\u0103 un mod de transmisie mai fiabil, dar mai lent, care permite transmiterea datelor peste TCP \u0219i TLSv1.3. <\/p>\n

Testele efectuate de compania ExpressVPN au ar\u0103tat c\u0103, comparativ cu vechile protocoale (ExpressVPN suport\u0103 L2TP\/IPSec, OpenVPN, IKEv2, PPTP, WireGuard \u0219i SSTP, dar nu se detaliaz\u0103 cu ce anume s-a realizat compara\u021bia), trecerea la Lightway a redus timpul de conectare \u00een medie cu 2.5 ori (\u00een mai mult de jum\u0103tate din cazuri, canalul de comunica\u021bie se stabile\u0219te \u00een mai pu\u021bin de o secund\u0103). Noul protocol a permis, de asemenea, reducerea num\u0103rului de \u00eentreruperi ale conexiunilor \u00een re\u021bele mobile nesigure, av\u00e2nd probleme cu calitatea semnalului, cu 40%. <\/p>\n

Dezvoltarea implement\u0103rii de referin\u021b\u0103 a protocolului va avea loc pe GitHub, oferind oportunitatea de participare la dezvoltare reprezentan\u021bilor comunit\u0103\u021bii (pentru a transmite modific\u0103rile, este necesar\u0103 semnarea unui acord CLA de transfer al drepturilor de proprietate asupra codului). De asemenea, sunt invita\u021bi la colaborare al\u021bi furnizori de VPN, care pot utiliza protocolul propus f\u0103r\u0103 restric\u021bii. <\/p>\n

Securitatea implement\u0103rii este confirmat\u0103 de rezultatul unui audit independent efectuat de compania Cure53, care a realizat anterior audituri pentru NTPsec, SecureDrop, Cryptocat, F-Droid \u0219i Dovecot. Auditul a implicat verificarea codului surs\u0103 \u0219i a inclus desf\u0103\u0219urarea de teste pentru identificarea posibilelor vulnerabilit\u0103\u021bi (\u00eentreb\u0103rile legate de criptografie nu au fost analizate). \u00cen general, calitatea codului a fost evaluat\u0103 ca fiind ridicat\u0103, \u00eens\u0103, auditul a identificat trei vulnerabilit\u0103\u021bi care pot duce la refuzul serviciului \u0219i o vulnerabilitate care permite utilizarea protocolului ca amplificator de trafic \u00een atacurile DDoS. Problemele men\u021bionate au fost deja rezolvate, iar comentariile formulate pentru \u00eembun\u0103t\u0103\u021birea codului au fost luate \u00een considerare. Auditul a mai ar\u0103tat \u0219i asupra vulnerabilit\u0103\u021bilor \u0219i problemelor cunoscute \u00een componentele ter\u021b\u0103 parte, cum ar fi libdnet, WolfSSL, Unity, Libuv \u0219i lua-crypt. \u00cen principal, problemele sunt nesemnificative, cu excep\u021bia MITM \u00een WolfSSL (CVE-2021-3336).
