In the present day, AES is one the most widely used and most secure Encryption Systems prevailing. So, naturally lots of research work is going on to mount a significant attack on AES. Many different forms of Linear and differential cryptanalysis have been performed on AES. Of late, an active area of research has been Algebraic Cryptanalysis of AES, where although fast progress is being made, t...

Recently a lot of attention is paid to the search for efficiently implementable MDS matrices for lightweight symmetric primitives. Most previous work concentrated on locally optimizing the multiplication with single matrix elements. Separate from this line of work, several heuristics were developed to find shortest linear straightline programs. Solving this problem actually corresponds to globa...

In October 2001, after a 3-year evaluation process, NIST announced its decision to propose the Belgian algorithm Rijndael for the AES. In this paper, we discuss some of the work that has been done on Rijndael since its selection as the AES. We also outline briefly the design of a related cipher, called Anubis, and compare both designs.

Alex Biryukov and Dmitry Khovratovich presented related-key attacks on AES and reduced-round versions of AES. The most impressive of these were presented at Asiacrypt 2009: related-key attacks against the full AES-256 and AES-192. We discuss the applicability of these attacks and related-key attacks in general. We model the access of the attacker to the key in the form of key access schemes. Re...

Japanese Encephalitis (JE) is a vector-borne disease of major importance in Asia. Recent increases in cases have spawned the development of more stringent JE surveillance. Due to the difficulty of making a clinical diagnosis, increased tracking of common symptoms associated with JE-generally classified as the umbrella term, acute encephalitis syndrome (AES) has been developed in many countries....

BACKGROUND The aim of the present study was to investigate the incidence of adverse events (AEs) during intra-hospital transport (IHT) of critically ill patients and evaluate the risk factors associated with these events. METHODS This prospective multicenter observational study was performed in 34 intensive care units in China during 20 consecutive days from 5 November to 25 November 2012. Al...

The Intel® Advanced Encryption Standard (AES) New Instructions (AES-NI) were designed to implement some of the complex and performance intensive steps of the AES encryption/decryption algorithm (cipher) using hardware acceleration. This paper presents the outcomes of a research project aimed at encryption/decryption analysis of the AES cipher in ECB, CBC, OFB, CFB, and CTR modes of operation on...
