Asimetrik \u015eifrelemenin Evrimi ve \u0130lk Referanslar\u0131<\/h2>\n

Asimetrik \u015fifreleme kavram\u0131, 20. y\u00fczy\u0131l\u0131n sonlar\u0131nda, simetrik \u015fifreleme \u015femalar\u0131nda kal\u0131c\u0131 bir sorun olan anahtar da\u011f\u0131t\u0131m sorununa \u00e7\u0131\u011f\u0131r a\u00e7an bir \u00e7\u00f6z\u00fcm olarak ortaya \u00e7\u0131kt\u0131.<\/p>\n

A\u00e7\u0131k anahtar \u015fifreleme fikri ilk kez 1976'da Whitfield Diffie ve Martin Hellman'\u0131n "Kriptografide Yeni Y\u00f6nler" ba\u015fl\u0131kl\u0131 makalesiyle kamuoyuna tan\u0131t\u0131ld\u0131. Makale, \u015fifreleme ve \u015fifre \u00e7\u00f6zme anahtarlar\u0131n\u0131n farkl\u0131 oldu\u011fu bir \u015fifreleme sisteminin olas\u0131l\u0131\u011f\u0131n\u0131 \u00f6ne s\u00fcrd\u00fc ve dijital imza kavram\u0131n\u0131 tan\u0131tt\u0131.<\/p>\n

Ancak bu kavramlar\u0131n ilk pratik uygulamas\u0131 Ronald Rivest, Adi Shamir ve Leonard Adleman taraf\u0131ndan ger\u00e7ekle\u015ftirildi. 1977'de en eski ve en yayg\u0131n olarak tan\u0131nan asimetrik \u015fifreleme algoritmas\u0131 olan RSA (Rivest-Shamir-Adleman) algoritmas\u0131n\u0131 geli\u015ftirdiler.<\/p>\n

Asimetrik \u015eifrelemeye Derin Bak\u0131\u015f<\/h2>\n

Asimetrik \u015fifreleme iki t\u00fcr anahtar kullan\u0131r: \u015fifreleme i\u00e7in herkesin bildi\u011fi genel anahtar ve \u015fifre \u00e7\u00f6zme i\u00e7in yaln\u0131zca al\u0131c\u0131n\u0131n bildi\u011fi \u00f6zel anahtar. Hem \u015fifreleme hem de \u015fifre \u00e7\u00f6zme i\u00e7in tek bir anahtar\u0131n kullan\u0131ld\u0131\u011f\u0131 simetrik \u015fifrelemenin aksine asimetrik \u015fifreleme, bu i\u015flevleri ayr\u0131\u015ft\u0131rarak daha sa\u011flam bir g\u00fcvenlik yap\u0131s\u0131 sa\u011flar.<\/p>\n
