In this paper, we revisit meet-in-the-middle attacks on AES in the single-key model and improve on Dunkelman, Keller and Shamir attacks of Asiacrypt 2010. We present the best attack on 7 rounds of AES-128 where data/time/memory complexities are below 2. Moreover, we are able to extend the number of rounds to reach attacks on 8 rounds for both AES-192 and AES-256. This gives the best attacks on ...

The Advanced Encryption Standard (AES) is the Federal Information Processing Standard for symmetric encryption. It is widely believed to be secure and efficient, and is therefore broadly accepted as the standard for both government and industry applications. If fact, almost any new protocol requiring symmetric encryption supports AES, and many existing systems that were originally designed with...

Acute Encephalitis Syndrome (AES) is a major public health problem in Bihar claiming thousands of lives every year in Bihar. Initially, the disease outbreak was focused in Muzaffarpur district of Bihar but recent trend shows that disease outbreak has spread its foci in many other districts as well. AES cases were recorded from district reporting units comprising Govt Medical College & Hospitals...

INTRODUCTION Cutaneous adverse events (AEs) have been observed in clinical studies of daclizumab high-yield process (HYP) in relapsing-remitting multiple sclerosis (RRMS). Here, we report cutaneous AEs observed in the randomized, double-blind, active-comparator DECIDE study (ClinicalTrials.gov identifier, NCT01064401). METHODS DECIDE was a randomized, double-blind, active-controlled phase 3 s...

BACKGROUND Some blood donation-related adverse events (AEs) can negatively impact the blood donor return rate (BDRR) and decrease donor retention. STUDY DESIGN AND METHODS One-thousand randomly selected whole-blood donors were interviewed 3 weeks after a 525-mL index whole-blood donation for seven AEs. The number of return visits and duration of follow-up were recorded for each of the 1000 do...

OBJECTIVES To describe the level, preventability and categories of adverse events (AEs) identified by medical record review using the Global Trigger Tool (GTT). To estimate when the AE occurred in the course of the hospital stay and to compare voluntary AE reporting with medical record reviewing. DESIGN Two-stage retrospective record review. SETTING 650-bed university hospital. PARTICIPAN...

OBJECTIVE The adverse events (AEs) with botulinum toxin type-A (BoNTA), used for indications other than spasticity, are widely reported in the literature. However, the site, dose, and frequency of injections are different for spasticity when compared to the treatment for other conditions and hence the AEs may be different as well. The objective of this study was to summarize the AEs reported in...

The identification and grading of adverse events (AEs) during the conduct of clinical trials is a labor-intensive and error-prone process. This paper describes and evaluates a software tool developed by City of Hope to automate complex algorithms to assess laboratory results and identify and grade AEs. We compared AEs identified by the automated system with those previously assessed manually, t...

In this paper, we examine algebraic attacks on the Advanced Encryption Standard (AES, also known as Rijndael). We begin with a brief review of the history of AES, followed by a description of the AES algorithm. We then discuss the problem of solving systems of multivariate quadratic equations over arbitrary fields (the MQ problem), as well as some recent general methods for solving it, namely r...

Differential Fault Analysis against AES has been actively studied these years. Based on similar assumptions of the fault injection, different DFA attacks against AES have been proposed. However, it is difficult to understand how different attack results are obtained for the same fault injection. It is also difficult to understand the relationship between similar assumptions of fault injection a...
