Bu \u00f6zellik kabaca \u015f\u00f6yle i\u015fliyor: Mesajla\u015fan taraflar i\u00e7in birer \u00e7ift anahtar \u00fcretiliyor. G\u00f6nderilen mesajlar \u015fifreleniyor ve bu \u015fifre yaln\u0131zca al\u0131c\u0131n\u0131n elindeki anahtarla a\u00e7\u0131labiliyor.<\/p>\n
Daha net anla\u015f\u0131labilmesi i\u00e7in X ve Y adl\u0131 iki kullan\u0131c\u0131 hayal edelim. X ve Y mesajla\u015f\u0131rken WhatsApp gibi u\u00e7tan uca \u015fifrelemeli bir uygulama kullan\u0131yor olsun. Mesajlar\u0131 \u015fifreleyebilen ve \u015fifresini \u00e7\u00f6zebilen anahtarlar, iki kullan\u0131c\u0131n\u0131n da cihaz\u0131nda kay\u0131tl\u0131 kal\u0131r. Uygulama X’in telefonunda bir anahtar ve Y’nin telefonunda bir anahtar kaydeder. X’in telefonu mesaj\u0131 anahtarla \u015fifreler, ard\u0131ndan \u015fifrelenmi\u015f mesaj\u0131 Y’nin telefonuna iletir. Y’nin telefonu anahtar\u0131 otomatik olarak devreye sokar ve mesaj\u0131n \u015fifresini \u00e7\u00f6zer. B\u00f6ylece Y, mesaj\u0131n i\u00e7eri\u011fini g\u00f6rebilir.<\/p>\n
WhatsApp’ta t\u00fcm bu s\u00fcre\u00e7 otomatik i\u015fliyor. Yani kullan\u0131c\u0131n\u0131n mesajlar\u0131n\u0131 g\u00fcvenceye almak i\u00e7in herhangi bir ayar\u0131 etkinle\u015ftirmesine gerek kalm\u0131yor. B\u00f6ylece u\u00e7tan uca \u015fifreleme, WhatsApp\u2019\u0131n elinde herhangi bir mesaj veya g\u00f6r\u00fc\u015fme i\u00e7eri\u011fini tutmas\u0131na izin vermiyor.<\/p>\n
Bu da h\u00fck\u00fcmetlerin ve ba\u015fkalar\u0131n\u0131n, WhatsApp’tan belirli ki\u015filerin mesajlar\u0131n\u0131 talep etmesini ve almas\u0131n\u0131 imkans\u0131z hale getiriyor.<\/p>\n
\u00d6te yandan CIA ve di\u011fer istihbarat te\u015fkilatlar\u0131n\u0131n ya da hackerlar\u0131n telefonlara uzaktan eri\u015fim sa\u011flama amac\u0131yla casus yaz\u0131l\u0131m kullanmas\u0131n\u0131n u\u00e7tan uca \u015fifreleme protokol\u00fcyle bir ilgisi yok.<\/p>\n
Zira casus yaz\u0131l\u0131mlarla bireylerin cihazlar\u0131na bizzat eri\u015fim sa\u011flan\u0131yor ve faaliyetleri bu \u015fekilde g\u00f6r\u00fcnt\u00fcleniyor. Bu, otob\u00fcste yan\u0131n\u0131zda giden bir yolcunun WhatsApp mesajlar\u0131n\u0131 g\u00f6rebilmenize benzer bir s\u00fcre\u00e7. Dolay\u0131s\u0131yla u\u00e7tan uca \u015fifreleme bu konuda koruma sa\u011flayabilecek bir protokol de\u011fil.<\/p>\n

Ancak bu, teknik olarak olduk\u00e7a karma\u015f\u0131k, pahal\u0131 ve genellikle yaln\u0131zca y\u00fcksek \u00f6neme sahip hedefler i\u00e7in uygulanan bir y\u00f6ntem.<\/p>\n
