We design a practical and provably-secure block ciper over small domain and non-binary inputs,which also can be referred......

While most reversible data hiding in encrypted images (RDH-EI) are based on stream cipher, this paper aims to present an......

Automatic search of impossible differentials for block ciphers is useful for impossible differential cryptanalysis.This ......

As a combination of algebraic attacks and side channel attacks, the ASCA (Algebraic Side-Channel Attack) has become a ve......

Feistel schemes are important components of symmetric ciphers, which have been extensively studied in the classical sett......

We study further the method of concatenating the outputs of two functions for designing an APN or a differentially 4-uni......

Ｓ－盒是许多密码算法的唯一非线性部件，它的密码强度决定了整个密码算法的安全强度。但是对于大的Ｓ－盒的构造比较困难，而且软硬件实现也比......
