混合式區塊加密法

Abstract

要設計一個新的區塊加密方法大致可分為兩種方式：一種是設計一個 新的運算方式與結構方法；另一種則是組合現存的區塊加密法。現有的區 塊加密方法組合方式是 product cipher 與 cascade cipher。我們在這 篇論文將提出一個新的區塊加密法組合方式—混和式區塊加密法，作為組 合區塊加密方法的另一種選擇。 To design a new block cipher, one way is to use some new mathematical operation and computing structures; another is to combine the existing block ciphers. The subsistent methods for combining block ciphers are product ciphers and cascade ciphers. In this paper, we propose a new method for combination of block ciphers, hybrid block ciphers, to be an alternative way of combining block ciphers.
