Abstract. Biclique cryptanalysis was proposed by Bogdanov et al. in Asiacrypt 2011 as a new tool for cryptanalysis of block ciphers. A major hurdle in carrying out biclique cryptanalysis is that it has a very high query complexity (of the order of 2 for AES-128, 2 for AES-192 and 2 for AES-256). This naturally puts a big question mark over the practical feasibility of implementing biclique atta...
Advanced Encryption Standard (AES) block cipher system is widely used in cryptographic applications. The main core of AES block cipher is the substitution table or SBox. This S-box is used to provide confusion capability for AES. The aim of this paper is to design dynamic S-box which depends on the secret key. The parameters of the new created SBOXes have characteristics equal to those in the o...
BACKGROUND The national incidence of adverse events (AEs) in Swedish orthopedic care has never been described. A new national database has made it possible to describe incidence, nature, preventability and consequences of AEs in Swedish orthopedic care. METHODS We used national data from a structured two-stage record review with a Swedish modification of the Global Trigger Tool. The sample wa...
OBJECTIVES To examine the causes of adverse events (AEs) and potential prevention strategies to minimise the occurrence of AEs in hospitalised patients. METHODS For the 744 AEs identified in the patient record review study in 21 Dutch hospitals, trained reviewers were asked to select all causal factors that contributed to the AE. The results were analysed together with data on preventability ...
Rotating Sbox Masking (RSM) scheme is a lightweight and highly efficient first-order masking scheme proposed to protect cryptographic implementations like AES from side channel attacks. It is a Low Entropy Masking Scheme (LEMS) and has attracted special attention from academia and industry with its low overhead and high performance. The two public targets of DPA Contest v4 are both RSM-masked A...
We show that the so-called super S-box representation of AES – that provides a simplified view of two consecutive AES rounds – can be further simplified. In the untwisted representation of AES presented here, two consecutive AES rounds are viewed as the composition of a non-linear transformation S and an affine transformation R that respectively operate on the four 32-bit columns and on the fou...

BACKGROUND Adverse events (AEs) are patient injuries caused by medical care. Previous studies have reported increased mortality rates and prolonged hospital length of stay in patients having an AE. However, these studies have not adequately accounted for potential biases which might influence these associations. We performed this study to measure the independent influence of intensive care unit...
