轻量级密码算法MIBS的零相关和积分分析

MIBS是适用于RFID和传感资源受限环境的轻量级分组算法。该文构造了一些关于MIBS的8轮零相关线性逼近，结合密钥扩展算法的特点和部分和技术，对13轮MIBS-80进行了多维零相关分析。该分析大体需要262.1个已知明文和274.9次加密。此外，利用零相关线性逼近和积分区分器之间的内在联系，推导出8轮的积分区分器，并且对11轮的MIBS-80进行了积分攻击，大体需要260个选择明文和259.8次加密。

Integral and Zero-correlation Linear Cryptanalysis of Lightweight Block Cipher MIBS

MIBS is a light weight block cipher for constrained resources environments such as RFID tags and sensor networks. This paper investigates the construction of zero-correlation linear approximations of 8-round MIBS and presents an attack on 13-round MIBS-80 by means of zero-correlation linear cryptanalysis with the properties of key schedule and partial-sum technique, which needs 262.1 known plaintexts and 274.9 encryptions. Furthermore, an 8-round integral distinguisher is deduced from the zero-correlation linear approximations using the relations between them, and as an application, integral attack on 11-round MIBS-80 is conducted with 260 chosen plaintexts and 259.8 encryptions.
