Intel Cascade Cipher : ウィキペディア英語版 | Intel Cascade Cipher
In cryptography, the Intel Cascaded Cipher, is a relatively new, high bandwidth block cipher, used as an optional component of the Output Content Protection DRM scheme of the Microsoft Windows Vista operating system. The cipher is based on Advanced Encryption Standard (AES) operating in counter mode, used for generating keys, and a 3-round version of Serpent for encrypting actual content. The Cascaded Cipher has not been subject to an open peer review process. A license for using the Cascaded Cipher is required from Intel Corporation. ==Description== The Cascaded Cipher specifications are not currently available on the Intel web site or in academic journals. A description of the structure of the cipher appears in a US patent application. In this case, the patent application only describes the inventive steps as claimed by its inventors, and is not a specification of the cipher as it is intended to be used to protect content in Windows Vista. There are two embodiments of the cipher described in the US patent application.
