Abstract
Nakledilen dijital verilerin kaydedilmesi için bir yöntem olup, bu yöntemde, nakledilen dijital bilgiler CW, bir kayit sifreleme anahtari E(NE) kullanilarak sifrelenmekte ve sonuçtaki sifrelenmis ECM mesaji kayit destek ortaminda depolanmaktadir. Bundan baska, kayit sifreleme anahtarinin E(NE) bir esdegeri sifrelenmis ECM mesaji ile birlikte destek ortaminda depolanan bir EMM mesajini olusturmak üzere bir RT(A) kayit tasima anahtari ile sifrelenmektedir. Bir düzenlemede, kayit tasima anahtari bir merkezi yetkilendirme birimi tarafindan üretilmekte ve yönetilmektedir. Seçenek olarak, kayit tasima anahtari, örnegin, anahtarin kayit cihazinda üretilmesi ve bir halinin korunmak üzere dekodere iletilmesi ile, kullanicinin dekoder ve kayit cihazi konfigürasyonu içinde üretilebilmekte ve yönetilebilmektedir.
