Adverse events (AEs) occur in health care and may result in harm to patients especially in the field of surgery. Our objective was to analyze AEs in surgical patient care from a nationwide perspective and to analyze the frequency of AEs that may be preventable. In total 19,141 randomly selected admissions in 63 Swedish hospitals were reviewed each month during 2013 using a 2-stage record review...
AES is the best known and most widely used block cipher. Its three versions (AES128, AES-192, and AES-256) differ in their key sizes (128 bits, 192 bits and 256 bits) and in their number of rounds (10, 12, and 14, respectively). In the case of AES-128, there is no known attack which is faster than the 2 complexity of exhaustive search. However, AES-192 and AES-256 were recently shown to be brea...
The block cipher Rijndael has undergone more than ten years of extensive cryptanalysis since its submission as a candidate for the Advanced Encryption Standard (AES) in April 1998. To date, most of the publicly-known cryptanalytic results are based on reduced-round variants of the AES (respectively Rijndael) algorithm. Among the few exceptions that target the full AES are the Related-Key Crypta...
S-box is a unique nonlinear operation in Rijndael, one encryption algorithm chosen as AES, and it determines the performance of AES. In this paper, the weaknesses in complexity and security of AES S-box are analyzed. We propose to increase the complexity and security of AES S-box by modifying the affine transformation and adding an affine transformation. Performance analysis demonstrates that t...
Objectives: Using an exercise intervention to improve lumbopelvic control (LPC) can enhance the pain severity and disability of participants with non-specific low back pain (NSLBP). The present study aimed to compare dynamic neuromuscular stabilization (DNS) exercises and common aquatic exercises (AEs) in terms of improving the pain, disability, LPC, and spinal posture of patients with non-spec...
We propose and analyse a new countermeasure against Differential Power Analysis (DPA) for the AES encryption algorithm, based on permutation tables. As opposed to existing AES countermeasures, it does not use random masking. We prove that our new countermeasure is resistant against first-order DPA; we also show that it is quite efficient in practice.
In this paper, we show that all the coordinate functions of the advanced encryption standard (AES) round function are equivalent under an affine transformation of the input.We also show that such affine relations will always exist if the AES S-box is replaced by any bijective monomial over GF(28). © 2005 Elsevier B.V.

T he AES 29th Conference, Audio for Mobile and Handheld Devices, was held at the conference center (see photo inset) on the beautiful campus of Seoul National University located in the thriving metropolis (background photo) of Seoul, Korea on September 2–4 2006. The conference was a significant milestone for AES. It was the first AES conference held in Asia. It was also the first conference dev...
