摘要: 介绍分组密码统一描述模型建立的背景和现实可行性,通过对现有大量分组密码算法结构的研究,对算法各个部分的功能进行归纳,提取分组密码算法的多个通用组件,给出从2种不同角度建立的分组密码统一描述模型——模型的组件关系形式和分组密码流程形式,并对各个通用组件进行了定义和功能说明,应用该模型描述Camellia算法。

Abstract: This paper introduces the background and feasibility of building the unified description model for block cipher. Studying on structure of many block ciphers and inducing the function of every part of it, it concludes many universal components of block ciphers. It presents the unified description model for block cipher in the form of relationship between components and the flow of block cipher, and supplies the definition and function instruction of all components, and applies the model on the camellia.

Key words: block cipher, unified describing model, structure of Feistel, S box
