One of the important features of the Grain family is that the throughput can be increased at the expense of additional hardware. Grain 128a is designed by Martin Ågren,〔 Martin Hell, Thomas Johansson and Willi Meier. == Description of the cipher == Grain 128a consists of two large parts: Pre-output function and MAC. The pre-output function has an internal state size of 256 bits, consisting of two registers of size 128 bit: NLFSR and LFSR. The MAC supports variable tag lengths w such that The cipher supports two modes of operation: with or without authentication, which is configured via the supplied $IV\_0$ such that if $IV\_0=1$ then authentication of the message is enabled, and if $IV\_0=0$ authentication of the message is disabled. 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「Grain 128a」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.
