Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Allogeneic hematopoietic stem cell transplantation (alloHSCT) is an essential therapy for several malignant and nonmalignant diseases, but relapse and graft loss remain the principal threats to its success. Routine monitoring of chimerism and minimal residual disease (MRD) enables early detection of imminent recurrence and guides ...

A New Image Encryption Algorithm Based on Single S-Box and Dynamic Encryption Step
IEEE Access, 2021 Chaotic-based S-box image encryption schemes promise to be a practical solution for securing digital images. However, the high-dimensional continuous chaotic has increased the algorithm’s complexity.

Identifying Patterns of Hospitalizations Among Childhood Cancer Survivors: A Population‐Based Study
Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Childhood cancer survivors (CCSs) experience more hospitalizations than the general population. We aimed to identify distinct hospitalization patterns among Queensland CCSs and the associated characteristics. Methods Cases (aged ≤14 years) diagnosed between 1995 and 2019 while residents of Queensland were identified through the ...

Side-Channel Analysis of Chaos-Based Substitution Box Structures
IEEE Access, 2019 There is a theoretically strong relationship between chaos and cryptology. In practice, one of the most successful applications of this relationship is chaos-based s-box structures.

A Novel Optimization Method for Constructing Cryptographically Strong Dynamic S-Boxes
IEEE Access, 2020 The resistance of S-box-based cryptosystems to linear cryptanalysis is often determined by the nonlinearity (NL) and the linear approximation probability (LAP) of the underlying S-box.

Perfect nonlinear S-boxes [PDF]
, 2007 A perfect nonlinear S-box is a substitution transformation with evenly distributed directional derivatives. Since the method of differential cryptanalysis presented by E. Biham and A. Shamir makes use of nonbalanced directional derivatives, the perfect nonlinear S-boxes are immune to this attack.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Pediatric refractory immune thrombocytopenia (rITP) is generally characterized by persistent thrombocytopenia and failure to achieve a sustained response to multiple standard therapies. We report a 4‐year‐old female with congenital tufting enteropathy, post‐intestinal transplant patient on immunosuppressants, who developed severe rITP ...

A depth-16 circuit for the AES S-box [PDF]
, 2011 New techniques for reducing the depth of circuits for cryptographic applications are described and applied to the AES S-box. These techniques also keep the number of gates quite small. The result, when applied to the AES S-box, is a circuit with depth 16

A new cryptosystem based on an enhanced Vigenere cipher incorporating large SBoxes [PDF]
E3S Web of ConferencesThe present paper explains the development of an innovative cryptographic system designed to encrypt color images at the pixel level. This technique relies on a significant enhancement of the conventional Vigenere method, incorporating the implementation
