    Reversible data hiding scheme based on pixel-value differencing in dual images by Pyung-Han Kim, Kwan-Woo Ryu, Ki-Hyun Jung

    Published 2020-07-01
    “…In the proposed scheme, the cover image is divided into non-overlapping blocks and the maximum difference value is calculated to hide secret bits. On the sender side, the length of embeddable secret data is calculated by using the maximum difference value and the log function, and the decimal secret data are embedded into the two stego-images after applying the ceil function and floor function. …”

    Security evaluation for parameters of SIMON-like cipher based on neural network distinguisher by Zezhou HOU, Jiongjiong REN, Shaozhen CHEN

    Published 2023-04-01
    “…The neural distinguisher is a new tool widely used in crypto analysis of some ciphers.For SIMON-like block ciphers, there are multiple choices for their parameters, but the reasons for designer’s selection remain unexplained.Using neural distinguishers, the security of the parameters (a,b,c) of the SIMON-like with a block size of 32 bits was researched, and good choices of parameters were given.Firstly, using the idea of affine equivalence class proposed by Kölbl et al.in CRYPTO2015, these parameters can be divided into 509 classes.And 240 classes which satisfied gcd(a-b,2)=1 were mainly researched.Then a SAT/SMT model was built to help searching differential characteristics for each equivalent class.From these models, the optimal differential characteristics of SIMON-like was obtained.Using these input differences of optimal differential characteristics, the neural distinguishers were trained for the representative of each equivalence class, and the accuracy of the distinguishers was saved.It was found that 20 optimal parameters given by Kölbl et al.cannot make the neural distinguishers the lowest accuracy.On the contrary, there were 4 parameters, whose accuracy exceeds 80%.Furthermore, the 4 parameters were bad while facing neural distinguishers.Finally, comprehensively considering the choice of Kölbl et al.and the accuracy of different neural distinguishers, three good parameters, namely (6,11,1),(1,8,3), and(6,7,5) were given.…”
