Abstract

This paper focuses on similarity properties and extension of the classical slide property of block ciphers. Taking FESH, an award-winning block cipher of the National Cryptographic Algorithm Design Competition 2019, as an example, similarity properties of the encryption and key transformation are found, owing to the similar structures that the encryption and key transformation adopted, and the constants generation. Based on the similarity properties, extended slide properties can be constructed for FESH. Slide attacks of FESH are then proposed. The similarity properties and extended slide property are immune to the increasing of iterated rounds, i.e., it cannot be avoided by increasing the round number of FESH. Furthermore, extended slide property helps relaxing the strict requirements of the subkeys in slide attacks. Taking Feistel and SPN structures as examples, frameworks of slide attacks based on the extended slide properties are presented. Slide attack of FESH is exactly a concrete example of SPN structure.

区块密码 FESH 的相似性和滑动攻击

本文重点研究了块密码的相似性特性和经典滑动特性的扩展。以2019年全国密码算法设计大赛获奖的区块密码FESH为例，由于加密和密钥变换采用了相似的结构，以及常数的生成，发现了加密和密钥变换的相似性。根据相似性属性，可以为 FESH 构建扩展的滑动属性。然后提出了对 FESH 的滑动攻击。相似性属性和扩展滑动属性不受迭代轮数增加的影响，即不能通过增加 FESH 的轮数来避免。此外，扩展滑动属性有助于放宽滑动攻击中对子密钥的严格要求。本文以 Feistel 和 SPN 结构为例，介绍了基于扩展滑动特性的滑动攻击框架。FESH 的滑动攻击正是 SPN 结构的一个具体实例。
