Intel Cascade Cipher
In cryptography, the Intel Cascaded Cipher is a 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.
