A ap\u0103rut versiunea 1.4 a serverului proxy outline-ss-server, care utilizeaz\u0103 protocolul Shadowsocks pentru a ascunde natura traficului, a ocolit firewall-urile \u0219i a p\u0103c\u0103lit sistemele de inspec\u021bie a pachetelor. Serverul este dezvoltat de proiectul Outline, care ofer\u0103 \u00een plus un wrapper pentru aplica\u021bii client \u0219i o interfa\u021b\u0103 de gestionare, permi\u021b\u00e2nd desf\u0103\u0219urarea rapid\u0103 a serverelor multi-utilizator Shadowsocks bazate pe outline-ss-server \u00een medii cloud publice sau pe echipamentele proprii, gestionarea acestora prin intermediul unei interfe\u021be web \u0219i organizarea accesului utilizatorilor prin chei. Dezvoltarea \u0219i \u00eentre\u021binerea codului sunt gestionate de Jigsaw, o subdiviziune a Google, creat\u0103 pentru a dezvolta instrumente de ocolire a cenzurii \u0219i a organiza un schimb liber de informa\u021bii. <\/p>\n

Outline-ss-server este scris \u00een limbajul Go \u0219i este distribuit sub licen\u021ba Apache 2.0. Codul proxy-ului a fost bazat peserver<\/a> go-shadowsocks2, creat de comunitatea dezvoltatorilor Shadowsocks. Recent, activitatea principal\u0103 a proiectului Shadowsocks s-a concentrat pe dezvoltarea unui nou server \u00een limbajul Rust, iar implementarea \u00een limbajul Go nu a mai fost actualizat\u0103 de mai bine de un an \u0219i este semnificativ \u00een urm\u0103 \u00een ceea ce prive\u0219te func\u021bionalitatea. <\/p>\n

Diferen\u021bele dintre outline-ss-server \u0219i go-shadowsocks2 se rezum\u0103 la suportul pentru conectarea mai multor utilizatori printr-un singur port de re\u021bea, capacitatea de a deschide mai multe porturi de re\u021bea pentru a accepta conexiuni, suportul pentru repornirea la cald \u0219i actualizarea configur\u0103rii f\u0103r\u0103 \u00eentreruperea conexiunilor, instrumentele \u00eencorporate de monitorizare \u0219i modificare a traficului pe baza platformei prometheus.io.

\"Lansarea<\/center> <\/p>\n

\u00cen outline-ss-server a fost ad\u0103ugat\u0103, de asemenea, protec\u021bia \u00eempotriva atacurilor legate de trimiterea cererilor de verificare \u0219i reproducerea traficului. Atacul prin cereri de verificare vizeaz\u0103 determinarea existen\u021bei proxy-ului; de exemplu, atacatorul poate trimite c\u0103tre serverul Shadowsocks \u021bint\u0103 seturi de date de dimensiuni diferite \u0219i poate analiza ce volum de date serverul va citi \u00eenainte de a determina o eroare \u0219i a \u00eenchide conexiunea. Atacul de reproducere a traficului se bazeaz\u0103 pe interceptarea sesiunii \u00eentre client \u0219i serverul<\/a> ulterior, \u00eencercarea de a retransmite datele interceptate pentru a determina existen\u021ba proxy-ului. <\/p>\n

Pentru a proteja \u00eempotriva atacurilor prin cereri de verificare, serverul outline-ss-server nu \u00eentrerupe conexiunea \u0219i nu afi\u0219eaz\u0103 erori \u00een cazul \u00een care se primesc date incorecte, ci continu\u0103 s\u0103 accepte informa\u021biile, ac\u021bion\u00e2nd ca un fel de gaur\u0103 neagr\u0103. Pentru a preveni reproducerea datelor trimise de client, informa\u021biile sunt verificate suplimentar pentru duplicate prin sume de control, p\u0103strate pentru ultimele c\u00e2teva mii de secven\u021be handshake (maximum 40 de mii, dimensiunea este configurat\u0103 la pornirea serverului \u0219i consum\u0103 20 de octe\u021bi de memorie pe secven\u021b\u0103). Pentru a bloca r\u0103spunsurile repetate de la server, \u00een toate secven\u021bele handshake ale serverului se aplic\u0103 coduri de autentificare HMAC cu etichete de 32 de bi\u021bi. <\/p>\n

\u00cen ceea ce prive\u0219te nivelul de ascundere a traficului, protocolul Shadowsocks, \u00een implementarea outline-ss-server, este similar cu transportul \u00eenglobat Obfs4 din re\u021beaua anonim\u0103 Tor. Protocolul a fost creat pentru a ocoli sistemul de cenzur\u0103 a traficului din China (\u201eMarele firewall chinezesc\u201d) \u0219i permite ascunderea eficient\u0103 a traficului redirec\u021bionat prin alt server (traficul devine greu de identificat datorit\u0103 ata\u0219\u0103rii unei \u0219ablon\u0103ri aleatorii \u0219i simul\u0103rii unui flux continuu). <\/p>\n

Protocolul utilizat pentru proximizarea cererilor este SOCKS5 \u2014 pe sistemul local se ruleaz\u0103 un proxy cu suport SOCKS5, care tunelizeaz\u0103 traficul c\u0103tre un server remote, de unde se efectueaz\u0103 efectiv cererile. Traficul dintre client \u0219i server este plasat \u00eentr-un tunel criptat (se suport\u0103 criptarea autenticat\u0103 AEAD_CHACHA20_POLY1305, AEAD_AES_128_GCM \u0219i AEAD_AES_256_GCM), ascunderea faptului de creare a acestuia fiind obiectivul principal al Shadowsocks. Se suport\u0103 organizarea tunelurilor TCP \u0219i UDP, precum \u0219i crearea de tuneluri arbitrare, nelimitate la SOCKS5, prin utilizarea pluginurilor, asem\u0103n\u0103toare cu transporturile \u00eenglobate din Tor.
