An improved key expansion algorithm based on a 2D discrete hyper chaotic map with memristor
Key expansion plays an important role in symmetric block cipher. To generate desired number of round keys that satisfy irreversibility, parallelism and independence, we first constructed a 2D memristor-based d...

Bit-level image encryption algorithm based on random-time S-Box substitution
To solve the shortcomings of traditional cryptography such as 3DES, AES and SM4 in encrypting multimedia information, we proposed a bit-level image encryption algorithm based on chaos and S-Box. First, we cons...

Design an irreversible key expansion algorithm based on 4D memristor chaotic system
The cryptanalysis results of AES show that its key expansion algorithm exists some weaknesses, such as the most round-constant are linear, and any round key can be derived from its previous or next round key, ...

Critical state behaviors of a coarse granular soil under generalized stress conditions
Critical state line (CSL) is the central concept in soil mechanics. A series of true triaxial compression tests under the constant- $${...
