Feistel cipherとは 意味・読み方・使い方

To provide a cipher computing circuit in which a measure is realized for a DPA scheme being conducted after the completion of the operations of a cipher computing circuit that packages Feistel type cipher algorithm.例文帳に追加

Ｆｅｉｓｔｅｌ型暗号アルゴリズムを実装した暗号演算回路の演算終了の後に行われるＤＰＡ法の対策を実現した暗号演算回路の提供。 - 特許庁

To provide a Feistel common-key block cipher processing configuration for reducing cost and memory storage data.例文帳に追加

低コストかつメモリ記憶データの削減を可能としたＦｅｉｓｔｅｌ型共通鍵ブロック暗号処理構成を実現する。 - 特許庁

The cipher computing circuit, on which the Feistel type cipher algorithm is packaged, is provided with a function computing section 24 in which the nonlinear function F is computed and a means which supplies random number data, that are not related to the cipher computing result, to the section 24 after ciphered data are outputted.例文帳に追加

Ｆｅｉｓｔｅｌ型暗号アルゴリズムを実装した暗号演算回路は、非線形関数Ｆを演算する関数演算部２４と、暗号化データの出力の後に、関数演算部２４へ暗号演算結果とは無関係の乱数データを供給する手段とを備える。 - 特許庁
