翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Self-Protecting Digital Content ： ウィキペディア英語版 Self-Protecting Digital Content Self Protecting Digital Content (SPDC), is a copy protection (Digital Rights Management) architecture which allows restriction of access to, and copying of, the next generation of optical discs and streaming/downloadable content. == Overview == Designed by Cryptography Research, Inc. of San Francisco, SPDC executes code from the encrypted content on the DVD player, enabling the content providers to change DRM systems in case an existing system is compromised. It adds functionality to make the system "dynamic", as opposed to "static" systems in which the system and keys for encryption and decryption do not change, thus enabling one compromised key to decode all content released using that encryption system. "Dynamic" systems attempt to make future content released immune to existing methods of circumvention. ==Playback method== If a method of playback used in previously released content is revealed to have a weakness, either by review or because it has already been exploited, code embedded into content released in the future will change the method, and any attackers will have to start over and attack it again. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Self-Protecting Digital Content」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
